The incubation period of tick-borne encephalitis in humans. The main symptoms of diseases transmitted through a tick bite Tick how long the bite lasts

V summer period there is a high chance of getting a tick bite. This topic must be treated with extreme scrupulousness. To date, tick bites in humans are quite common. This combination of circumstances can lead to serious consequences and even a threat to life. Going on a picnic in the forest, you must follow some rules of conduct there. If a tick is found, submit it for examination. These and many other questions will be discussed below.

ICD-10 code

A84 Tick-borne viral encephalitis

A69.2 Lyme disease

Incubation period after a tick bite in humans

Infection occurs directly through the bite of an arthropod. It is the tick that is the carrier of many dangerous diseases for humans. There were cases when infection occurred through the gastrointestinal tract. No, you don't need to eat the tick. But cases of tick ingestion, thus, in the body were recorded, but only in animals. It is enough for a person to simply consume the milk of an animal that is infected. The incubation period in humans after a tick bite can last up to 30 days. In some cases, it is delayed for 2 months.

Most often, the first symptoms begin to manifest themselves 7-24 days after the bite. There were cases when a sharp deterioration in the condition was observed after 2 months. Therefore, health needs to be monitored. The incubation period is completely dependent on the blood-brain barrier. The weaker it is, the faster the disease will manifest itself, if any. You need to pay attention to all strange symptoms, including an ordinary headache. This will allow you to quickly identify the disease and eliminate it.

Symptoms of a tick bite in humans

If the bite was made by an infected tick, then the person has a risk of getting serious diseases. One of them is tick-borne encephalitis. With rapid development, it leads to damage to the nervous system and can lead to inflammation of the brain. Disability and death are not ruled out. The main symptoms after a tick bite begin to pester a person after a week.

Symptoms after a bite are very similar to the onset of an acute respiratory disease. A person feels a general malaise, body temperature rises, body aches appear. All this may indicate the presence of an infection in the body. A slightly different symptomatology is observed in the disease with borreliosis. The whole danger lies in the fact that there may not be any signs until six months. Then the bite site begins to turn red and all the above symptoms appear.

Vomiting, migraine, chills can act as auxiliary symptoms. The human condition is rapidly deteriorating. On the fourth day after the onset of the manifestation of the disease, sluggish paralysis may develop. Sometimes it affects the larynx and pharynx, because of this it becomes difficult for a person to swallow. There were cases when the reaction was so strong that there were disturbances in the work of the respiratory system and heart. Epileptic seizures are possible.

What does a tick bite look like on a human?

Attachment of the tick to the human body occurs through an organ - the hypostome. It is an unpaired outgrowth capable of performing the functions of the sense organs. With the help of his tick is attached and sucks the blood. Most often, a tick bite in humans is observed in places with delicate skin, and looks like a red spot, with a dark dot in the middle. It is necessary to look for it on the abdomen, lower back, groin, armpits, on the chest and in the ears.

Allergic reactions may occur at the suction site. After all, flare saliva and microtrauma negatively affect human skin. Suction is painless, so a person does not feel it. The bite site is reddened, and has a round shape.

The bite of a tick, a carrier of the disease borreliosis, looks more pronounced. It is characterized by the appearance of a specific patchy erythema. The speck is able to change size and reach up to 10-20 cm in diameter. In some cases, all 60 cm were recorded. The spot has a rounded shape, sometimes it takes the form of an irregular oval. Over time, an elevated outer border begins to form, it acquires a bright red hue. In the center of the spot, the skin becomes bluish or white. The stain is somewhat reminiscent of a bagel. A crust and scar gradually form. After a couple of weeks, the scar disappears on its own.

Signs of an encephalitic tick bite in humans

It must be understood that a small tick bite can lead to serious problems with health. Thus, encephalitis can cause limb paralysis and lead to lethal outcome. There is no need to panic ahead of time. You should be able to distinguish the symptoms and, if they appear, immediately consult a doctor. The likelihood of a favorable outcome is high if signs of a bite were found in a person encephalitis tick at an early stage.

The first thing is chills. A person thinks that he has an ARVI or flu. Therefore, he begins treatment according to his own standard scheme, but it does not help. An increase in temperature is added to the chill, sometimes its indicator is 40 degrees. At the next stage, a headache and nausea appear, sometimes all this is supplemented by vomiting. The person is still sure it's the flu. Severe headaches are replaced by body aches. Breathing gradually begins to be difficult, a person is not able to move normally. His face and skin are rapidly reddening. This indicates that the virus has begun its harmful activity. After that, irreversible processes begin in the body. Paralysis or death is possible.

Diseases after a tick bite in humans

A tick bite is safe, but only if the tick was not a carrier of any disease. The whole danger lies in the fact that most diseases manifest themselves over time. A person forgets about bites and continues to live as before. Meanwhile, the disease begins to actively progress, all this is accompanied by certain symptoms. Therefore, it is worth noting that after a tick bite, a person may develop the following diseases: tick-borne encephalitis, borreliosis, tick-borne acarodermatitis and dermatobiasis. The first two diseases are of particular danger.

Ehrlichiosis in humans from a tick bite

This is a dangerous infection that can enter the body after a tick bite. It can be cured with effective treatment. If it is not started, the person will die. Ehrlichiosis is caused by bacteria that are transmitted by a tick bite into the body. The likelihood of getting such a disease increases if a person is often in areas where ticks are spread. It is worth noting that a person can develop ehrlichiosis from a tick bite. However, not all ticks are carriers of the disease.

Borreliosis in humans from a tick bite

Lyme disease is caused by spirochetes of the genus Borrelia. The phenomenon is common on all continents, so avoiding infection is not so easy. A person who has Lyme disease is not dangerous to others. Bacteria, along with saliva, enter the skin of a person, after a few days they begin to actively multiply. The danger lies in the fact that from a tick bite a person can develop borreliosis, with further damage to the heart, joints and brain. Bacteria can live in the human body for years and gradually lead to a chronic form of the disease.

The incubation period is 30 days. On average, symptoms begin to manifest themselves after 2 weeks. In almost 70% of cases, this is reddening of the skin, the so-called erythema. The red spot can change its size and change. Ultimately, the bite site becomes covered with a crust, the skin may remain pale or become cyanotic. A red hill appears around the site of the lesion, all this visually resembles a donut. After a couple of weeks everything disappears. But the danger has not passed, after a month and a half, damage to the nervous system and heart may occur.

Tick-borne encephalitis from a tick bite

Tick-borne encephalitis is a natural focal infection that in most cases affects the human nervous system. This can lead to disability and even death. Infection occurs from a tick bite, which can provoke tick-borne encephalitis. People who like to spend a lot of time in nature are subject to such influence. They need to take extra care and constantly inspect their body for the presence of a tick.

The first signs after a bite can manifest themselves after a week. Sometimes it takes a whole month. First of all, chills begin, accompanied by an increase in body temperature and a feverish state. A person sweats intensely, he is plagued by a severe headache and body aches. If the symptoms do not manifest themselves for a long time, even slight muscle weakness can serve as a cause for panic.

It is necessary to seek help with a sharp increase in body temperature, strong head pain, sleep disturbance. Often the disease can cause hallucinations and convulsions. All these symptoms should be a reason to go to the hospital.

The consequences of a tick bite in humans

A tick bite can cause a number of diseases. Naturally, if you do not pay attention to this, serious consequences are possible. So, most often from a tick bite, a person can develop irreparable consequences. They arise due to untimely treatment of encephalitis, borreliosis, acarodermatitis and dermatobiosis.

• Encephalitis can lead to serious consequences. Often it affects the central nervous system and heart. A person may develop difficulty breathing, eventually paralysis appears. If treatment is not started on time, the victim may remain disabled or die.
• Borreliosis. The danger of defeat lies in the fact that the disease can be "silent" for six months. During this period, irreparable changes can occur in the body. So, borreliosis manifests itself in the form of erythema. Redness may appear at the site of the bite, progress over time and eventually disappear. The most terrible thing begins later, a month later, serious disorders of the central nervous system and heart develop. Lethal outcome is not excluded.
• Acarodermatitis. There are no consequences after such a defeat. A person can be pestered by local allergic reactions, but all this passes with time. The disease does not affect internal organs and systems.
• Dermatobiasis. The disease is especially dangerous for children. If the eggs from the abdomen of the tick begin to hatch in the body, a fatal outcome is possible. The child's body is not able to cope with this problem, even with high-quality treatment.

Complications after a tick bite in humans

After a tick bite, various complications can develop. First of all, the central nervous system suffers. Perhaps the development of epilepsy, headaches, paralysis. The cardiovascular system is also affected. It is not excluded the appearance of arrhythmia, constant jumps in blood pressure. The lungs also suffer, pneumonia can develop, and as a result of this, pulmonary bleeding. The kidneys and liver are affected negatively. In this case, after a tick bite, a person develops complications, in the form of nephritis and digestive disorders.

Encephalitis is of particular concern. V best case everything will end with chronic weakness. The body itself is able to resume after a couple of months. In severe cases, the process can take up to six months. In the worst case, a person will develop defects that will interfere with his normal life. Persistent changes in the body lead to epilepsy and disability.

Temperature when bitten by a tick in humans

A sharp increase in body temperature a few hours after the bite indicates that the body responded to such an invasion with an allergic reaction. This happens due to the saliva of a sterile or infected tick getting under the skin. Therefore, when a tick bites, a person needs to constantly record the temperature, moreover, it is necessary to monitor the victim for 10 days. Body temperature must be constantly measured. Fever can manifest itself 2-10 days after the bite. This symptom indicates the beginning of infectious pathogenesis.

With tick-borne encephalitis, the temperature may rise 2-4 days after the bite. It lasts for two days and then normalizes on its own. Repeated increase is fixed on the 10th day. with borreliosis, body temperature does not change so often. With ehrlichiosis, fever appears on the 14th day. Moreover, it can be increased for 20 days. Therefore, temperature indicators must be monitored without fail.

Redness after a bite

This symptom is characteristic of Lyme disease. The place where the tick is sucked is redder and resembles a ring. This can happen 3-10 days after the defeat. In some cases, there is a skin rash. Over time, the redness after the bite changes size and becomes much larger. For borreliosis, the appearance of erythema is characteristic. It is accompanied by severe fever, headache, and fatigue. Motor restlessness, muscle and joint pains are not excluded. Often there is swelling of the tonsils.

Over the next 3-4 weeks, the rash begins to gradually disappear and the stain may disappear completely. A person, as a rule, does not pay attention to all this. The danger still remains. So, after a month and a half, severe complications from the central nervous system may appear. Therefore, redness and, in general, tick bites must be monitored without fail!

Lump at the site of a tick bite

Often the human body responds negatively to the introduction of a tick into it. So, the bite site begins to turn red, in some cases a seal appears. What is causing all this and is there any danger in it. It should be understood that an ordinary allergic reaction can cause a bump at the site of a tick bite. It occurs due to the piercing of the skin with a proboscis and the ingress of saliva into them. Moreover, it is not necessary that the saliva be infected, even in a sterile form, it can provoke an allergic reaction. Itching, redness and slight induration are normal reactions of the body. But, it's not worth it to relax.

If the tick was submitted for examination, and it confirmed the absence of dangerous bacteria in it, there is no reason to worry. When a bump appears after a while, and the tick has not been checked, there is a reason to worry. You need to go to the hospital immediately. This may indicate an infection. Diseases caused by ticks have been described above.

A bump may occur due to improper removal of the tick. In some cases, the body of the tick is safely removed, but its proboscis remains in the skin. Therefore, the removal process must be monitored carefully. If a bump appears and additional symptoms in the form of fever and headache, you should immediately go to the hospital.

Diarrhea after a tick bite

Intestinal upset is not so common, but it can be one of the signs of a serious damage to the body. Each person is individual and even the bite of an uninfected tick can lead to a number of negative reactions. The site of the lesion may turn red, with time itching and a rash appear. The intestines are also able to react negatively after a tick bite, causing diarrhea.

This symptom is twofold. In one case, it may indicate the weakness of the body, in the other - to talk about its infection. Therefore, if negative symptoms appear, including intestinal upset, you should go to the hospital. Even if the person became better after a while. Many diseases carried by ticks begin to manifest themselves 2 weeks after the bite. During this period, the infection can develop in the body and lead to irreversible processes.

Consolidation after a bite

Compaction after a bite may indicate an infection has entered the body. If this symptom appears along with redness, itching and a rash, you should immediately consult a doctor. This can be both improper removal of the tick, and the development of a serious disease. Often, after a bite, a seal forms, its development provokes an allergic reaction. Perhaps this is the most harmless thing that can happen.

Piercing the skin with its proboscis, the tick begins to stick. This process can cause itching, redness, and even rawness. Often, after removal, a seal appears. True, this symptom is not so harmless. It is likely that an infection has begun to develop in the human body. It could be encephalitis or borreliosis. You should immediately seek help from the hospital.

Often people incorrectly remove the tick itself. This causes its proboscis to remain in the skin. In this regard, the inflammatory process begins, there is a strong irritation and compaction. To cope with this problem, doctors will help.

Treatment after a tick bite in humans

The first step is to remove the tick. You can do this both on your own and by contacting the hospital. A live tick must be preserved and taken for examination. If it was killed during removal, it is worth placing it in a container with ice. In any case, the tick must be submitted for examination! After all, bites can cause a number of dangerous diseases. It is important that after a tick bite a person is correctly diagnosed with a disease and an effective treatment is prescribed.

The bite is treated with antibiotics. True, they are not always used to eliminate the causative agent of infection. To eliminate encephalitis, antibiotics are not used.

• Tick-borne encephalitis. First of all, a person needs to provide bed rest. It is desirable that it be at least a week. In the first three days, the victim should take human immunoglobulin. It is recommended to resort to the help of such means as: Prednisolone, Ribonuclease. Blood substitutes are also suitable, these are Reopoliglyukin, Poliglukin and Hemodez. If meningitis is observed, an increased dose of B vitamins and ascorbic acid is recommended. In case of respiratory failure, intensive ventilation of the lungs is used.
• The treatment regimen for borreliosis is somewhat different. The first step is to hospitalize the patient. At the stage of manifestation of erythema, he should use Tetracycline. Bacteriostatics play a special role in the treatment. It can be Lincomycin and Levomycetin. If a neurological syndrome is observed, then it is stopped by intravenous injections of bactericidal antibiotics. It can be Azlocillin and Piperacillin. The water balance is restored by means of blood substitutes such as Reopoliglyukin and Poliglukin

Where to go for symptoms of a tick bite in humans?

When bitten by a tick, you need to follow a special algorithm. The first step is to remove the tick. After that, it is handed over to a special accredited laboratory. This will allow him to identify the presence of infectious agents. The study is performed by PCR, directly in the body of the tick. A person needs to donate blood to detect antibodies. After all, bites can cause serious consequences. The victim is recommended to undergo a course of treatment based on the results of laboratory tests. When symptoms of a flare bite appear in a person, you need to know where to go.

Where can you take a tick and how to check it. It is necessary to find a hospital that does such research. The address of laboratories and phone numbers can be found on the Internet. Just visit the Ukrpotrebnadzor website. In fact, ticks should be taken in every hospital that has a laboratory. Most importantly, the study is completely free! This information is recommended to be corrected. The results are provided on the day the tick is taken or the next day.

How to treat a tick bite in humans?

If a tick is found on the body, it must be removed immediately. An experienced specialist can help with this. In the hospital, the tick is immediately submitted for examination, because a tick bite in a person can provoke the development of serious diseases, so you need to know how to treat the affected area. In an outpatient setting, a person is recommended to use immunoglobulins. The most commonly prescribed remedy is Rimantadine. It is taken for 3 days, one tablet in the morning and in the evening.

At home, the tick is removed with oil. It is necessary to drop a lot of it on the head of the tick. Alcohol is also used for these purposes. After 15 minutes, you can start removing. In most cases, the tick crawls out on its own. It is much easier to remove it this way, just use tweezers and pull out the tick in a circular motion. The bite site is recommended to be treated with hydrogen peroxide. Further advice can be obtained from the hospital. Usually, the site of the lesion is not treated with anything else.

Tablets from a tick bite in humans

If there is a risk of a person developing encephalitis or the diagnosis has been confirmed, start taking human immunoglobulin. It can be Prednisolone and Ribonuclease. Blood substitutes are actively used, such as Reopoliglyukin, Poliglukin. All these tablets from a tick bite do not give infection, spread throughout the human body and lead to serious lesions in the body.

• Prednisolone. The dosing regimen is individual. Usually the remedy is applied once a day. It is actively used to eliminate the effects of a tick bite. It is not recommended to take the drug in the presence of fungal infections and intolerance. Perhaps the development of hypokalemia, flatulence, sleep disturbance and negative nitrogen balance.
• Ribonuclease. For the treatment of tick-borne encephalitis, the drug is administered intramuscularly 6 times a day. The dose may be adjusted. It is not worth using the remedy for respiratory failure, bleeding and tuberculosis. Perhaps the development of allergic reactions.
• Reopoliglyukin and Poliglukin. Means are administered intravenously, at a rate of 60 drops per minute. The maximum quantity is 2.5 liters. They can not be used for skull injuries and diabetes. May lead to the development of allergic reactions. Rarely causes arterial hypotension.
• With borreliosis, several other drugs are used. Reopoliglyukin and Poliglukin are also used as hematopoietic medicines. In the initial stages of erythema, Tetracycline is used, as well as bacteriostatics: Levomycetin and Lincomycin. Azlocillin and Piperacillin are used as bactericidal antibiotics.
• Tetracycline. The tool can be used both in the form of tablets and ointments. The ointment is applied to the affected area every 6 hours. As for tablets, they are used 250-500 mg with the same frequency. Do not use the product for children under the age of eight, as well as for pregnant women. It is not excluded the development of diarrhea, constipation, allergic reactions.
• Levomycetin and Lincomycin. When taken orally, the dose is up to 500 mg. In this amount, funds are used up to 4 times a day. The duration of treatment is usually 10 days. It is impossible to use drugs for violations of the functionality of the liver and kidneys. A similar requirement is put forward for children and pregnant women. Development is possible: leukopenia, depression and skin rash.
• Azlocillin. The agent is administered intravenously. The maximum dosage is 8 grams. That is, 2 grams 4 times a day. It should not be taken by people with allergic reactions. Able to provoke nausea, vomiting, anaphylactic shock.
• Piperacillin. The drug is administered intravenously over 30 minutes. The daily dose is 100-200 mg. The medication is administered up to 4 times a day. You can not take it with hypersensitivity, pregnancy and lactation. It can lead to headache, skin hyperemia and dysbacteriosis.

Prevention of tick bite in humans

Prevention is entirely based on a few basic rules. The first thing to do is get vaccinated. This will avoid serious consequences in the future. If a person is already infected, it is not advisable to carry it out. The second criterion for prevention is specific immunotherapy. It is a therapeutic measure in which immunoglobulin is introduced into the human body. Prevention of a tick bite should be more carefully carried out in people whose activities are directly related to working in nature.

It is important to dress properly when hiking in the forest or in nature. Special clothing will prevent the tick from getting under it. You can use special deterrents. It can be both sprays and creams that are applied to the skin. All this will avoid a bite and further infection. Compliance with simple rules and checking the body after returning from nature will protect a person and prevent possible serious consequences.

Forecast

The further course depends on how quickly the person reacted to the defeat. If he ignored the symptoms and did not go to the doctor, the prognosis is extremely unfavorable. The fact is that tick bites can manifest themselves only after a while. This is the main danger. The first symptoms may appear within a week and fade away after a few days. Then she flares up new force, but already entails serious damage to the central nervous system and brain. This can lead to the development of epilepsy, paralysis, disability and even death. Naturally, the prognosis in this case is unfavorable.

If a person noticed a tick in time, removed it and submitted it for examination, the probability of a good outcome is high. After all, even if the tick is infected, according to the results of the examination, a person will be prescribed high-quality treatment. This will prevent all serious consequences. The favorable prognosis depends entirely on the person himself.

Death from a tick bite in humans Death after a tick bite can occur for a number of reasons. In most cases, this is due to infection with serious diseases such as encephalitis and borreliosis. Many people ignore their symptoms and do not rush to see a doctor. Meanwhile, the disease begins to actively progress. Of particular danger is encephalitis, from such a tick bite in people death can occur.

The disease can manifest itself at the initial stage, and then fade away. After that, it returns with renewed vigor and leads to serious damage to the central nervous system and brain. Often this causes death. Borreliosis also carries a danger. It can manifest itself six months after infection. And everything happens instantly. Animals can die instantly. Finally, dermatobiasis. This disease causes death in children. The body of adults is more adapted to this infection.

General information about ticks

Ticks are seasonal. The first cases of attacks are registered in early spring when the air temperature becomes above 0 0 C, and the latter - in the fall. The peak of bites is observed from April to July.

Bloodsuckers do not like the bright sun and wind, so they lie in wait for their prey in damp, not too shady places, in dense grass and bushes. Most often found in ravines, on the edges of forests, along the edges of paths or in parks.

Tick ​​attack and bite

The tick gnaws through the skin with the help of a hypostome (oral apparatus) dotted along the edges with outgrowths facing backwards. This structure of the organ helps the bloodsucker to be firmly held in the tissues of the host.

With borreliosis, a tick bite looks like focal erythema up to 20–50 cm in diameter. The form of inflammation is most often correct, with an outer border of bright red color. After a day, the center of erythema turns pale and acquires a bluish tint, a crust appears and soon the bite site is scarred. After 10-14 days, there is no trace of the lesion.

Signs of a tick bite

• there is weakness, a desire to lie down;
• chills and fever occur, possibly fever;
• photophobia appears.

Attention. In people in this group, symptoms may be supplemented reduced pressure, increased heart rate, itching, headache and enlargement of nearby lymph nodes.

V rare cases there is difficulty breathing and hallucinations.

Temperature after a bite as a symptom of the disease

Each infection caused by the bite of a bloodsucker has its own characteristics:

1. With tick-borne encephalitis, a relapsing-type fever appears. The first rise in temperature is recorded 2-3 days after the bite. After two days everything is back to normal. In some cases, there is a repeated increase in temperature for 9-10 days.
2. Borreliosis is characterized by a fever in the middle of the disease, which is accompanied by other symptoms of infection.
3. With monocytic ehrlichiosis, the temperature rises 10-14 days after the tick bite and lasts about 3 weeks.

Almost all diseases transmitted by bloodsuckers are accompanied by fever.

Rules of conduct for a tick bite

So, what to do if bitten by a tick? First of all, it is necessary to remove the bloodsucker as soon as possible. This should be done slowly and carefully so as not to damage it and not provoke infection. In this case, do not use gasoline, nail polish and other chemical substances. Vegetable oil or fat will not help either. It is better to use effective and proven methods.

Removing a tick with a thread

The method is simple, but requires a lot of dexterity and patience. It will be useful when extracting large individuals. For the procedure to be successful, it is recommended to perform the following steps:

Removing a tick with a thread

The removed bloodsucker must be placed in a glass container with a tight lid and delivered to the laboratory for research.

Removing a tick with tweezers

Attention. The tweezers during the removal of the bloodsucker must be kept strictly parallel or perpendicular to the skin.

Tick ​​twisters

Tick ​​twisters are very effective

Other ways to remove a tick

1. Wrap your fingers in a handkerchief or gauze to make it easier to hold the tick.
2. Grab it at the very border with the skin and pull it out with smooth twisting movements.
3. Disinfect the wound or rinse with water.

If for some reason the tick cannot be saved for analysis, it should be destroyed by pouring boiling water or burning it on fire.

Attention. If you can not remove the bloodsucker yourself, you must contact the nearest emergency room.

Medical workers will provide first aid in case of a tick bite: they will professionally remove it and send it for research, disinfect the wound and tell you how to behave further. The doctor will definitely inform you what symptoms you should pay attention to in the next month.

What to do after removing a tick?

In people who are prone to allergies, a tick bite can cause a strong body response. Often swelling of the face develops, difficulty breathing and muscle pain appear. In this case it is necessary:

• give the victim an antihistamine: Suprastin, Claritin, Zirtek;
• provide access fresh air, unbutton clothes;
• call an ambulance.

All other diagnostic and therapeutic measures are carried out only in a hospital setting.

Researching ticks for diseases is recommended as soon as possible.

If the tick could not be kept alive, it is recommended to donate blood for the detection of immunoglobulins to infections for early diagnosis of the disease. The analysis is carried out quickly, the result is usually ready in 5-6 hours. If there was a vaccination, when donating blood, you must indicate its date. The presence of vaccine antibodies can be confusing for healthcare professionals.

Diseases caused by tick bites

Encephalitis and borreliosis are the most common diseases caused by tick bites.

For Russia, the most significant diseases from a tick bite are tick-borne encephalitis, Lyme borreliosis and zoonotic infections. Let's consider them in a little more detail.

Attention. The virus is transmitted through the bite of a tick. Often, the transmission of the pathogen is recorded by the alimentary route - through infected cow or goat milk that has not been boiled.

The asymptomatic course of the disease is very common and can reach 85–90% in some foci. Prolonged bloodsucking significantly increases the risk of pronounced forms of pathology. The virus is well tolerated low temperatures, but quickly dies when heated to 80 ° C.

Infection with tick-borne encephalitis is seasonal. The first peak of the disease occurs in May-June, the second is recorded in August - early September.

During a bite, the pathogen immediately enters the human blood through the salivary glands of the tick, where it is in the highest concentration. After a few hours, the virus enters the central nervous system of the victim, and after 2 days it can be detected in the brain tissues. The incubation period of encephalitis with a tick bite is 14-21 days, with infection through milk - no more than a week.

Symptoms of tick-borne encephalitis

Most victims have an asymptomatic form of infection, and only 5% have a pronounced form. Tick-borne encephalitis most often begins suddenly with the following symptoms:

• elevated to 39-40 ° C body temperature;
• Strong headache;
• sleep disturbance;
• nausea leading to vomiting;
• diarrhea;
• redness of the skin of the face and upper body;
• weakness, decreased performance.

Such symptoms are characteristic of a febrile form of the disease, which disappears after 5 days. There is no CNS involvement in this case.

Symptoms of tick-borne encephalitis - this is how a person who becomes ill after a tick bite looks like

Meningeal and meningoencephalitic forms of pathology are much more severe. The patient complains of lethargy, apathy and drowsiness. There are hallucinations, delirium, impaired consciousness, convulsions like epileptic seizures. The meningoencephalitic form can be fatal, which is a rarity in recent years.

Periodic muscle twitching indicates damage to the peripheral nerves. A polyradiculoneuritic form of encephalitis develops, in which the general sensitivity is impaired. In the polioencephalomyelitis form of the disease, paresis of the arms and legs is observed.

Lyme disease (Lyme borreliosis)

Distributed in the northern regions of Russia. The causative agent enters the human blood when bitten by ixodid ticks and can persist in the body for years. The first symptoms of the disease include:

• headache;
• temperature rise to 38-39 ° C;
• fatigue, weakness and apathy.

1–3 weeks after a tick bite, a seal and annular erythema appear at the suction site, which can reach 20–50 cm in diameter.

Circular erythema - the main symptom of borreliosis

Attention. Despite the fact that a few weeks after the bite, the red spot disappears without a trace, it is necessary to conduct an analysis for the presence of the causative agent of Lyme borreliosis, since the disease has serious complications and can be transmitted from pregnant to child.

Often, the CNS, heart, muscles and ligaments, joints and organs of vision are involved in the pathological process. Late diagnosis and untimely therapy can lead to chronic borreliosis, which often ends in disability.

erlichiosis

The disease is also carried by ixodid ticks. Deer are considered the main reservoir of erlichias, dogs and horses act as an intermediate reservoir.

Ehrlichiosis can be asymptomatic or clinically pronounced, even fatal. Common signs of the disease include:

• fever
• increased sweating;
• weakness, drowsiness;
• nausea up to vomiting;
• rigor.

In the acute phase of ehrlichiosis, anemia, a decrease in the level of platelets and leukocytes in the blood, is observed.

relapsing tick fever

The infection is usually registered in the south of Russia, in Armenia, Uzbekistan, Tajikistan, Georgia and Kyrgyzstan. The disease always occurs suddenly and begins with a bubble at the site of a tick bite. Then other symptoms are added to the skin manifestations:

• fever;
• increased body temperature;
• aches in the joints;
• nausea and vomiting;
• headache.

Gradually, the bubble becomes bright red, a pronounced rash appears on the patient's body, the liver enlarges, the skin and whites of the eyes turn yellow.

Rash with tick-borne typhus

The disease is undulating. The acute phase usually lasts from 3 to 5 days, then the victim's condition returns to normal, the temperature drops. A few days later, everything repeats again. There can be many such episodes. Each subsequent proceeds with less severity.

Coxiellosis

It is one of the most common zoonotic infections in the world. The carrier of the disease can be both farm animals and wild ones. One of the distributors of the pathogen is a tick, most often ixodid. He is able to keep rickettsia in the body for a long time and pass them on to offspring. The first symptoms appear 5-30 days after the tick bite:

• increased sweating;
• elevated temperature;
• dry, exhausting cough;
• loss of appetite;
• redness of the face and upper body;
• migraines, weakness and drowsiness.

Often, Q fever is accompanied by pneumonia, back pain, and muscle pain. The temperature in the first days of the disease can change several times during the day. Such a disease is treated only in a hospital, therapy lends itself well and recovery occurs quickly. Complications are rare, the outcome of the disease is most often favorable. A person who has been ill with coxiellosis develops strong immunity.

Treatment of victims of a tick bite

If a tick has bitten and, according to the results of the tests, an infection is detected, the patient is given immunotherapy based on the doctor's prescriptions. Further treatment depends on the type of pathogen that has entered the body.

Therapy of patients with tick-borne encephalitis

There are currently no specific treatments for tick-borne encephalitis. If signs of damage to the central nervous system appear, the victim must be hospitalized for medical care. The treatment regimen includes:

1. Bed rest during the whole fever and a week after it ends.
2. In the first days of the disease, the introduction of immunoglobulin is indicated. To achieve the best result, it is necessary to apply the remedy as soon as possible, preferably in the first three days after a tick bite.
3. In general cases, the patient is prescribed corticosteroid drugs, blood substitutes.
4. With meningitis, increased doses of vitamins B and C are administered.
5. In case of deterioration of respiratory functions, the victim is shown artificial ventilation of the lungs.

During the recovery period, the patient is prescribed nootropics, tranquilizers and testosterone simulators.

As an addition to the main treatment, antibiotics may be prescribed for the victim of a bite. Antimicrobials are used to suppress pathogenic microflora that can cause various complications.

Therapy of patients with borreliosis

Treatment for Lyme borreliosis involves taking antibiotics. They are used to suppress spirochetes - the causative agents of the disease. The most commonly used drugs are penicillins and cephalosporins. To stop erythema, antimicrobial agents of the tetracycline group are prescribed.

Antibiotics are used to treat borreliosis

With the appearance of neurological disorders, the victim is hospitalized. In the hospital, complex therapy is carried out, including:

• blood substitutes;
• corticosteroids;
• testosterone mimics;
• nootropics to improve cerebral circulation;
• vitamin complexes.

The outcome of borreliosis depends on the timely detection of a tick bite, the correct diagnosis and early initiation of therapy. Illiterate treatment often leads to the chronic phase of Lyme disease, which is stopped with great difficulty and can result in disability or death of the victim.

Attention. For the treatment of infections of a protozoal nature, drugs are used that exclude further growth and development of protozoa.

Complications after a tick bite

Summarizing all of the above, we can draw a very disappointing conclusion about the consequences of a tick bite. As can be seen, infections affect the most important systems body:

• lungs - with the development of symptoms of pneumonia and pulmonary bleeding;
• liver - there is a violation of digestion, problems with stools (diarrhea);
• CNS - with frequent headaches, hallucinations, paresis and paralysis;
• cardiovascular system - arrhythmia appears, blood pressure jumps;
• joints - arthritis and arthralgia are formed.

The consequences of a tick bite can develop in two ways. With a favorable outcome, loss of working capacity, weakness and lethargy continue for 2–3 months, then all body functions return to normal.

With an illness of moderate severity, recovery lasts up to six months or longer. A serious form of the disease requires a rehabilitation period of up to 2-3 years, provided that the disease proceeded without paralysis and paresis.

With an unfavorable outcome, there is a persistent and prolonged (or permanent) decrease in the quality of life of the victim of a tick bite. Manifested by impaired motor function. The clinical picture worsens significantly under the influence of nervous and physical overwork, pregnancy, regular alcohol intake.

Persistent disorders in the form of epileptic manifestations and spontaneous convulsions lead to the incapacity of the patient.

Disability as a result of a tick bite

As you know, there are 3 groups of disability. The degree of damage to the body after a tick bite is determined by a special medical commission:

1. Disability group III - mild paresis of the arms and legs, rare epileptic seizures, the inability to perform highly qualified work that requires accuracy and attention.
2. Disability of the II group - bright paresis of the limbs, partial paresis of the muscles, severe epilepsy with a change in the psyche, asthenic syndrome, loss of the ability to self-service.
3. Disability group I - acquired dementia, severe impairment of motor function, persistent and complete epilepsy, widespread muscle paresis, loss of self-control and inability to move independently.

In particular severe cases with inadequate treatment of infections caused by a tick bite or a complete lack of therapy, a fatal outcome is possible.

Prevention of tick bites

The main and main measure for the prevention of diseases transmitted by bloodsuckers is vaccination. The event significantly reduces the risk of infection after tick bites. Vaccination is necessary for people living in epidemiologically dangerous areas or people whose work is related to forestry.

Vaccination is the main measure to prevent diseases caused by tick bites.

Advice. Despite the limited risk group, it is better for everyone to be vaccinated. After all, it is not known where you are “lucky” to meet a tick.

Primary vaccination is allowed from early age. Adults can use domestic and imported drugs, children - only imported ones. You should not buy the vaccine yourself and bring it to the vaccination office. Still won't drive it. The drug requires very strict storage rules, compliance with a certain temperature and light regime, which is impossible to do at home. Therefore, it makes no sense to purchase an expensive drug and store it in the refrigerator.

There are two vaccination options:

1. Preventive vaccination. Helps protect against a tick bite for a year, and after additional vaccination - at least 3 years. Revaccinations are carried out every three years.
2. Emergency vaccination. Allows you to protect yourself from tick bites for a short time. For example, such a procedure will be necessary for an urgent trip to regions with high tick activity. While in epidemiologically dangerous areas, it is recommended to take jodantipyrin.

The introduction of the vaccine is carried out only after a detailed survey, visual inspection and temperature measurement. Persons with inflammatory diseases are not vaccinated until complete recovery.

How to protect yourself from a tick bite?

Going to an unfavorable zone, you should choose clothes of light colors:

• a shirt or jacket with cuffs and a tight collar, trousers tucked into boots;
• anti-encephalitis suit;
• a tight hood with drawstrings that protects the ears and neck from ticks;
• clothing should preferably be treated with insecticidal agents.

The best way not to "meet" a tick is to strictly follow all preventive measures.

To repel ticks, special insecticides based on DEET, however, repellents are not effective enough and require application every 2 hours. They can be processed open areas bodies and clothes.

More effective acaricides. Preparations are used for contact destruction of ticks. They can only be processed with outerwear worn over underwear.

Attention. Often on sale there are acaricides for application to the skin. However, they should be used very carefully. Possible severe allergic reaction and poisoning.

Tick-borne encephalitis insurance

V Lately widespread coverage of expenses associated with possible disease encephalitis after a "meeting" with a tick. Such a measure is often used as an addition to vaccination or as an independent measure.

Insurance for the costs associated with the treatment of a tick bite will not hurt anyone

Insurance will help pay for the expensive treatment of tick-borne encephalitis and other infections carried by bloodsuckers.

Attention. The article is for reference only. Competent diagnosis and treatment of diseases is possible only under the supervision of a specialist.

With the onset of warming, there is a high probability of finding a tick bite on the body. In summer, this problem becomes especially relevant and occurs more and more often. A bite can bring a lot of harm to health, and can become a serious threat to human life, so the problem should be taken seriously.

How to protect yourself from a tick bite? What to do if bitten by a tick? Let's look into these issues in detail.

Forest tick: how to recognize the threat

The consequences of such a bite are extremely severe (in case of infection and refusal of treatment):

• Paralyzes the body.
• There are problems with breathing.
• Decreased brain activity.
• Fatal outcome.

If a person has suffered from a sterile tick, then the complications may not be so dangerous:

• It rots the affected area.
• An allergic reaction occurs.
• Edema appears, Quincke's edema is possible.

It is impossible to independently determine whether an infectious tick has stuck or not. Their appearance and color does not depend on whether they are infected or not. If bitten by an infected tick, timely treatment can save the victim's life.

How long does it take for a tick bite to show symptoms?

The first symptoms appear after 2-3 hours in the form of. A week or later, the symptoms described above may appear.

How is a tick bite different from other insect bites?

How to find out which insect has bitten and left characteristic marks on the skin? There will be one spot, there will not be the same in the neighborhood, the redness will increase every hour, an allergic reaction may occur. Bedbugs, for example, bite in several places at once, fleas too. The bite of a mosquito and a midge is much smaller than a tick.

Can a tick bite without sucking?

Can a tick bite through clothes and pantyhose?

Why do ticks drink blood and how much do they need?

Ticks drink blood in order to get enough and leave offspring. Females will not be able to lay eggs in a hungry state, she definitely needs blood. How long can a tick draw blood? From several minutes to several hours, and females, as a rule, stay on the body of the victim longer. It should be noted that most of the time the tick is on the skin of a person or animal in search of a place for suction, so if the tick has not yet stuck, it should be brushed off as soon as possible (no need to press it on yourself like a mosquito, you can bring an infection under the skin) . On average, an adult sucks blood for 1-2 hours, after which it disappears.

How much blood can a tick drink at one time?

Hungry individuals ixodid tick weigh from 2 to 15 mg, and sated from 200 to 1200 mg, which is many times their own weight. In one bite, a tick can pump out up to 1000 mg of human blood. The size of a hungry tick does not exceed 4 mm, and a full one can reach 3 cm, becoming similar in size to a corn seed.

The photo compares two ticks - a recently sucked and drunk blood.

Does a tick die after being bitten?

Some people seriously think that a tick dies after it bites a person, but this is not at all the case. Apparently it is confused with a wasp or a bee, which dies after being stung. A tick, on the contrary, only benefits from a bite, this is its nutrition, which contributes to further development and reproduction. A hungry tick will not be able to leave offspring, so biting people and animals is a vital necessity for him.

How dangerous is a tick bite for a person?

A tick can serve as a carrier of a rather extensive list of diseases, so after pulling out a tick, it is better to save it for tests to determine infections (encephalitis, borreliosis, called Lyme disease), this is done in the laboratory at the infectious diseases hospital. It is worth noting that the presence of viruses in an insect does not guarantee that the bite victim will also get sick. It is necessary to examine the insect for peace of mind if the result is negative, and for timely treatment - if an infection is confirmed.

Most often transmitted and pose a huge threat to human life - and. Scientists have proven that the chance of getting infected from a tick is unlikely, since 90% of ticks, according to studies, are not infected. Although minimal, but the chance exists.

Is it possible to get infected from a tick if it crawled through the body?

If the tick just crawled over the surface of the skin, it is impossible to get infected from it. The first stage of infection begins precisely from the moment the tick sucks and injects an anesthetic substance under the skin. So if a tick crawls over you, brush it off as soon as possible and, if possible, with fire.

Bitten by a tick - what to do: first aid

If a tick is crawling on you, shake it off immediately, and if it has already stuck, then remove it as soon as possible and store it in a jar with moistened cotton wool or blades of grass to deliver it alive to the laboratory for the study and diagnosis of infections.

Treat the wound with an antiseptic. If signs of allergy are observed - severe redness and swelling of the bite site, immediately give the victim an antiallergic agent. You can purchase drugs "Zirteks", "Suprastin", "Prednisolone": the dosage regimen of drugs is individual. The action of one tablet is enough for a whole day. These antihistamines are actively used to eliminate the allergic effects of a bite. Taking the pill is not recommended for individual intolerance to the components. Perhaps the development of hypokalemia, sleep disturbances, flatulence and negative nitrogen balance.

If the encephalitis virus has entered the human body, the drug "Ribonuclease" is prescribed for treatment. The drug is administered 6 times a day intramuscularly, in a hospital. The dose is prescribed by the attending physician. The use of Ribonuclease is not recommended for respiratory failure, tuberculosis and bleeding. There is a risk of developing allergic conditions.

How to pull out a tick?

1. Movements in a circle counterclockwise, as if unscrewing a screw, pull it out of the skin with tweezers. Be careful not to break off the head of the tick.
2. If you had to extract the bloodsucker in nature, and there were no tweezers nearby, it will help ordinary thread. With its help, the proboscis is tied near the very surface of the skin and pulled out with light jerks.
3. After removal, you need to make sure that the tick is intact, put it in an airtight container and deliver it to the sanitary and epidemiological station for analysis as soon as possible.
4. Lubricate the surface near the bite with any antiseptic.

People often advise treating the affected area with oil, kerosene, gasoline and other liquids so that the tick crawls out on its own. This action is erroneous - the tick will try to dive even deeper under the skin. But if the insect then crawls out, its body will not be able to be examined in the laboratory.

What to do if the head of the tick remains under the skin?

The head of the tick may remain under the skin in case of careless, excessively sharp removal. It looks like a small splinter, so some are negligent about removing it, saying “the tick is dead, it no longer sucks out blood, it will fall off by itself” or simply do not notice. But it is not recommended to do so. Left under the skin, the proboscis of the tick will provoke inflammation and suppuration of the wound. Therefore, do not leave the head or proboscis of the tick under the skin, waiting for them to fall off on their own.

Take a sharp needle disinfected in alcohol and pick the remaining proboscis and remove it. After a bite, a small wound will remain on the skin, which will heal quickly if the tick was not contagious. Treat the bite site with peroxide, then brilliant green or iodine. If, use Fenistil gel or a similar remedy that relieves itching. Try not to scratch the inflamed area so that the healing process goes faster.

To prevent the head of the tick from remaining under the skin, cling to it as close as possible to the suction point.

What disease can be contracted from a tick bite?

After a tick bite, a person develops various ailments - from ordinary irritation to severe or fatal illness:

Modern drugs can completely cure infections that are transmitted by a tick, provided that it is detected in a timely manner and treatment is started immediately.

Signs of infection with tick-borne encephalitis

According to doctors, the symptoms of this encephalitis are detected after 10-14 days from the moment the victim was bitten by a tick. What to do? There is no need to panic, often elevated body temperature and muscle pain can be a manifestation of a protective psychological response of the body after fright and worries.

The onset of the disease goes through certain stages:

1. Causeless and short chills, fever up to 40 degrees. According to the clinical signs of the formation of encephalitis, this period is more like infection with the flu.
2. After some time, the patient may experience symptoms: nausea and vomiting, bouts of severe headache. At this stage, all symptoms indicate a gastrointestinal disorder.
3. A few days later, the patient suddenly develops symptoms of arthritis or arthrosis. Pain in the head passes, they are replaced by aches of the whole body. The patient's movements are very difficult, there are problems with breathing. The skin on the face and body turns red and becomes swollen, purulent abscesses appear at the site of the bite.
4. Further, the symptoms only worsen, because the infection enters the patient's circulatory system and begins its destructive work. Delay can lead to death!

If a tick is found on the body, it should be removed immediately. This procedure can be carried out independently or go to the hospital. Health workers can easily pull it out and run a series of tests. Only in laboratory conditions can you accurately determine whether this tick is dangerous. If treatment is necessary, it is necessary to unconditionally follow the recommendations and prescriptions of the attending physician so that the effectiveness of the treatment is maximum.

Treatment of tick-borne encephalitis

Mid-spring is the beginning of the peak season for the activation of ticks, from the attack of which no one is immune, therefore it is important to know the signs of a tick bite in a person in order to carry out emergency prevention or preventive treatment. Everything you need to know about the signs of a bite, the consequences, methods of treatment and prevention - in our article.

• taiga Ixodes Persulcatus;
• European forest Ixodes Ricinus.

The absence of eyes is compensated by a highly developed sense of smell and touch, the increased sensitivity of these organs enables the animal to respond with lightning speed to the proximity of the victim. During feeding, the back of the body of females stretches, allowing them to absorb a volume of blood many times greater than the body weight of a hungry individual. Males are less bloodthirsty: males stick for a short time, making up for the deficiency of nutrients.

Tick ​​attacks: features

If a tick has bitten, the characteristic symptoms in a person appear only after a certain time. How serious the consequences of an attack by a blood-sucking relative of insects can be is determined by a number of key points:

The reaction to a tick bite depends on the combination of the above conditions. The consequences of an arthropod attack are diseases of natural foci, including infection:

• encephalitis;
• borreliosis - neurological syndrome of Lyme disease;
• typhus, relapsing fever;
• hemorrhagic fever;
• Q-fever;
• tularemia;
• monocytic erchiliosis.

The attack of the female and male is equally dangerous. The attack of the male is short-term plus painless, so the wound is difficult to notice immediately. Cases of infection with encephalitis, when the victims deny the possibility of contact - good example male attacks.

Ticks in humans suck blood, plunging the head into the skin, pre-cutting the layers of the dermis, injecting an anesthetic along the way, fixing themselves inside by means of a hypostome - a special outgrowth resembling an anchor.

• abdomen
• neck/nape/ears;
• waist / back;
• chest;
• armpits;
• groin.

The result of a tick attack is a microtrauma of the skin. Tick ​​bite, symptoms are manifested by the development inflammatory process due to the action of the components of the saliva of the animal. The most "harmless" consequences are local allergic reactions, accompanied by redness of the suction area. When the effect of the anesthetic wears off, the skin begins to itch.

After an attack by a carrier of borreliosis, the bite site acquires a pronounced reddish tint, caused by intense expansion of the capillaries. After a while, an additional bright red border appears around the round or oval spot, the area inside turns blue or white.

A swelling after a tick bite or the formation of a bump-shaped seal is due to two reasons:

• allergic to the composition secreted by the salivary glands. Signs of a tick bite in an allergic person are determined by the degree of aggressiveness of the allergens secreted by the saliva of the animal plus the individual immune response;
• improper removal of the arthropod - part of the proboscis remains inside. The immune system recognizes a foreign protein compound, including a defense mechanism, the body reacts with swelling of the affected area, an abscess may occur.

Even when you are sure that the attacked tick is 100% a carrier of pathogens, the first signs appear only after a certain period of time.

Symptoms of an arthropod lesion

Outwardly, the first signs of a tick bite appear:

• headache;
• chills, fever;
• the development of tachycardia, lowering blood pressure;
• vomiting;
• deterioration in general well-being, apathy;
• swelling of the affected area;
• muscle weakness, numbness of the limbs;
• difficult breathing;
• decrease/loss of appetite;
• photophobia - painful perception of bright light by the eyes.

Rare cases of allergic reactions are accompanied by Quincke's edema, temporary paralysis.

The latent period of borreliosis, ehrlichiosis, encephalitis, anaplasmosis is a month. The swelling after a tick bite can last for a long time. The absence of temperature is a favorable sign. The beginning of the inflammatory process and the formation of an abscess becomes a reason to see a doctor. Self-manipulations - cauterization, heating, the use of ointments, are fraught with complications, consultation of a specialist is necessary.

Encephalitis: alarming symptoms

There are no characteristic signs of a tick bite in humans, confirming one hundred percent infection with the disease. Only laboratory staff will be able to confirm or deny the fact of infection of the bloodsucker. An attack by an infected arthropod implies the gradual multiplication of pathogens, given the absence of pronounced manifestations of the disease. The primary signs of an encephalitic tick bite in humans will appear after 8-10 days. The presence of immunodeficiencies, chronic diseases can accelerate the development of symptoms of the disease, so the state of health worsens after 3-4 days.

The onset of any form of pathology manifests itself similarly to the flu:

• febrile state accompanied high temperature up to 39.9°;
• body aches - muscle / joint pain;
• decrease in the vitality of the body;
• headache.

Active reproduction of pathogenic bacteria provokes fever, the duration of the period is 6-10 days. Possible various options development of events. A mild degree of the course of the disease implies recovery, rapid recovery of the body, and the production of antibodies that prevent re-infection. A rare occurrence is a change in the febrile form of the chronic course of the disease.

After the fever stage, a short remission may also occur, then the viral attack resumes, accompanied by similar fever symptoms. Overcoming the virus of the blood-brain barrier causes damage to the cells of the nervous system. A similar stage of encephalitis is characterized by the appearance of symptoms of meningitis. Virus attacks alternately disrupt the functioning of internal organs.

For different lesions, certain signs are characteristic:

1. The meningoencephalitic form is characterized by the appearance of hallucinations, pronounced mental changes, paralysis, paresis, and epileptic seizures.
2. The poliomyelitis form is distinguished by a number of signs characteristic of poliomyelitis, which causes a loss of the ability of the muscles of the neck and arms to move (paralysis).
3. The polyradiculoneurotic form is accompanied by damage to the peripheral nerves, loss of sensation in the muscles of the legs, and the development of a severe pain syndrome affecting the inguinal region.

An unfavorable outcome implies a significant reduction in the patient's quality of life. The result can be a violation of the functions of the musculoskeletal system. Progressive symptoms cause epilepsy of varying severity, hyperkinesis, pronounced mental disorders, severe asthenia - a person becomes disabled.

First aid

It is forbidden to pull the bloodsucker, use gasoline, kerosene, oil, vinegar, flooding the affected area with chemicals. Such manipulations are fraught with the death of the animal, relaxation of the oral apparatus, the ingress of the full volume of dangerous microbes into the blood, and an increased risk of developing diseases.

The wound will need to be treated with an antiseptic composition, minimizing the intensity of manifestation characteristic features defeat. Edema appeared, breathing became difficult - it is advisable to make an intramuscular injection of Prednisolone.

The ideal option is to examine a living individual through microscopy, finding out whether the victim was attacked by a sterile or infected individual. The damaged body is also covered with ice, delivering to the laboratory specialists. Employees of Rospotrebnadzor are engaged in research, address lists contain relevant sites.

Prevention and treatment of infections caused by blood-sucking arachnids

Symptoms and treatment of encephalitis exclude antibiotic therapy, meaning:

• compulsory hospitalization;
• bed rest, including a period of fever plus the entire following week, after the disappearance of acute influenza symptoms;
• the appointment of prednisolone, ribonuclease, rheopolyglucin, polyglucin, hemodez;
• the manifestation of signs of meningitis is eliminated by increased dosages of preparations containing vitamin B, ascorbic acid;
• breathing difficulties are facilitated by the use of IVL methods - intensive ventilation of the lungs;
• restorative therapeutic measures include courses of anabolic steroids, nootropics, and tranquilizers.

Treatment of Lyme borreliosis requires the mandatory use of antibiotics to help stop the negative effects of infection, quickly reducing the activity of spirochetes - the main causative agents of the disease. When the infection provoked a violation of the functions of the nervous system, the patient requires mandatory hospitalization.

Basic principles of drug therapy

1. To prevent the initial signs - the formation of a characteristic reddish spot, tetracycline drugs are called - antimicrobial agents that can effectively treat infections of various origins. The use of bacteriostatic agents helps to minimize the complications of late stages.
2. The development of the neurological syndrome of tick-borne borreliosis is stopped by courses of intravenous injections of antibiotics of the penicillin group, cephalosporins.
3. The disturbed water balance is restored by the use of saline, vitamins, prednisolone, agents that stabilize the circulation of the brain blood, and the use of anabolic steroids.

You need to know the following facts:

• Vaccination against encephalitis is guaranteed to protect against the disease.
• After 10 days, a blood test is carried out using PCR methods. Polymerase chain reaction reveals microorganisms that provoke the development of encephalitis, Lyme borreliosis.
• Two weeks later, a study is performed to determine the presence of antibodies that prevent infection with encephalitis.
• A month later, the presence of Lyme borreliosis antibodies can be detected.

The choice of antigenic material for vaccination, shown to any person who is a resident of a disadvantaged region, who has a profession that requires frequent stay in a forest area, includes several types of vaccines produced by Russia, Switzerland, Germany.

Vaccination with human immunoglobulin payable service. Free administration of gamma globulin is shown to individuals, according to the conditions of the encephalitis treatment program provided for by the voluntary medical insurance policy.

Russian-made vaccines

1. The use of a concentrated culturally purified inactivated dry vaccine is indicated for children who have reached the age of four. The developer is the M.P. Chumakov Institute.
2. The introduction of the drug Encevir, produced by the research and production association Microgen, is allowed from the age of 18 years.

Vaccines from the Austrian manufacturer BaxterVaccine AG

• the use of FSME-IMMUNE Injection is indicated for the age category 1-16 years;
• FSME-IMMUNE Junior is used similarly.

German preparations

• vaccine Encepur for children, allowed from the first years of life;
• use of Encepur adult, indicated from 12 years of age

Vaccinations are made by everyone interested, given the absence of contraindications. Primary vaccination can be given to children during the first year of life, preferably using imported drugs. Timely vaccination against tick-borne encephalitis is effective preventive measure, allowing to minimize the symptoms and consequences of a tick attack.

VIDEO: What to do if bitten by a tick

Everyone knows that ticks are encephalitic, but not everyone understands what this means. And the fact that they also carry other diseases is not known at all. We tell you the symptoms of which diseases can appear after a tick bite.

This article is intended for persons over 18 years of age.

Are you over 18 already?

Every year, as soon as the spring sun comes out, we gather a large company and go to nature to enjoy delicious shish kebab. And then the insects wake up, which are impatiently waiting for us there. We are used to mosquito bites, all the more it is enough to take a mosquito spray with you, but tick bites can lead to serious consequences.

The tick season usually begins in early April, but in recent years, the first bites have been reported by victims as early as March. It lasts until September-October, so even in summer we must not forget about these little pests. Why are ticks so dangerous, what diseases do they carry? Read on for more information about the symptoms that a person may experience after being bitten by a tick.

Tick ​​bite: symptoms in humans

V Europe experts know 15 diseases, and 7 of they are dangerous to people. These are Lyme disease (borreliosis), tick-borne encephalitis, ehrlichiosis, tick-borne relapsing fever, tularemia, babesiosis, spotted fever. The first 4 are the most common. These diseases appear after a tick bite, but the main danger in that some of they are asymptomatic.

Doctors never tire of reminding you that after a tick bite, you should immediately go to the hospital and take the tick for examination. Most people neglect this rule - they remove the tick and immediately forget about it. You can’t do this, and so that you are not among them, we will tell you what diseases these insects carry and what are the first symptoms of infection.

Borreliosis

In 1975, in the city of Lyme (Connecticut), many cases of rheumatoid arthritis in children and adults after contact with a tick were recorded. After the research, scientists were able to establish the cause of the disease - bacteria of the genus Borrelia.

The first signs of borreliosis appear later 7-14 days after a tick bite.Main symptoms:

• fever, chills;
• enlarged lymph nodes;
• nausea and vomiting;
• at the site of the bite - a bluish-red ring, its diameter gradually increases.

Bacteria affect literally all systems - nervous, circulatory, digestive, musculoskeletal. The disease penetrates all organs and tissues, and if at first the symptoms resemble ordinary poisoning, then by the 4th week they will develop into impaired speech and memory, facial paralysis, arrhythmia and dizziness.

Note that there is no vaccine for the prevention of borreliosis. The best prevention- protect yourself from being bitten.

erlichiosis

Bacteria of the genus Ehrlichia enter the human blood with tick saliva. The first signs appear after 7-20 days after the bite.The disease manifests itself in the following symptoms:

• increase in body temperature;
• pain in muscles and joints;
• general weakness;
• at the site of the bite - a watery vesicle (vesicle), which later turns into an ulcer and becomes covered with a crust.

Ehrlichiosis may be asymptomatic, especially in adults.

babesiosis

The Babesiidae bacteria that cause this disease infect red blood cells. Symptoms:

• dark color of urine;
• constipation and diarrhea (alternating);
• elevated temperature;
• general weakness;
• yellowness of the mucous membranes.

The disease can be asymptomatic, in which case it can be detected only after a blood test. It is also known how long after contact with a tick signs may appear: 7-15 days.

tick-borne relapsing fever

A very serious disease, the symptoms of which appear almost instantly:

• high temperature, up to 40C;
• headache and muscle pain;
• disorders of the nervous system.

Pay attention to how the bite looks: it turns into a small papule, and later a rash appears all over the body.

spotted fever

This disease manifests itself quite quickly - after 1-2 days after being bitten by an infected tick. Of the symptoms:

• elevated temperature;
• nosebleeds;
• nausea and vomiting;
• disturbances, temporary loss of consciousness.

After a few more days, hemorrhages can be seen on the mucous membrane, rashes appear on the skin, replaced by reddish nodules.

Tularemia

It's another one dangerous disease, which is transmitted through the bite of a tick. Of the first symptoms that can be found at home:

• swollen lymph nodes;
• lethargy and weakness;
• intoxication.

Treatment of the above diseases should begin immediately. Diseases can develop into a chronic form and even lead to death or disability. Moreover, after one bite, you can pick up several diseases from a tick at once!

After returning from the street, be sure to inspect the entire body for bites. Most often, a tick can be found on the head or on the leg - it is these areas of the skin that remain less protected.

As you can see, we talked about all the diseases, but we kept silent about one. Tick-borne encephalitis is a very serious disease and, unfortunately, the most common, so we will talk about it in more detail.

Symptoms of an encephalitic tick bite in humans

To begin with, we note that the word "encephalitic" does not refer to a tick belonging to a particular species: it means that it is infected with the encephalitis virus. What is this disease?

Viral encephalitis is an acute inflammation of the brain, accompanied by damage to the spinal cord, peripheral nerves. If treatment is not started in time, the disease begins to progress: a person’s speech and memory fail, intellectual abilities decrease, personality degradation / change occurs, paralysis and death are possible.

By appearance it is impossible to determine whether an insect is infected or not, which is why doctors ask you to bring ticks that you have suffered from for analysis in order to eliminate the risks of the disease.

Remember: after a tick bite, you need to urgently see a doctor. There are risks of contracting encephalitis if you do not feel well in the first few days, namely:

• you have elevated body temperature up to 39-40 C, chills;
• the bite site is reddened and very painful;
• you find it difficult to look at the light;
• a rash appeared on the body;
• have nausea and vomiting;
• you experience headache and weakness, aching muscles and joints.

With viral encephalitis, symptoms may subside within a few days, so it is easy to confuse it with the common cold. But after some time they repeat, and there can be about 10 such waves.

Symptoms may appear after 2 days, or after 3 weeks. Sometimes the disease is asymptomatic, and this encephalitis is even more dangerous, because the more the disease progresses, the more difficult it is to cure.

Summarizing all of the above, we can draw a specific conclusion: after a tick bite, you should immediately consult a doctor to eliminate the risks of diseases. When you remove a tick, try to do it as carefully as possible so that it remains alive. Then put it in a small jar - and run to the laboratory! You will also need to donate blood there.

But it is best to avoid tick bites. When going outdoors, wear closed shoes and long sleeves. Cover your neck, armpits, head, and tuck your pants into your socks. Girls must braid their hair and hide it under a hat or scarf. Don't forget about special means from insects.

Remember that ticks mostly live in bushes and dead wood, so do not climb there unless necessary. As soon as you get home, inspect all your belongings, shake them thoroughly. Only in this way will you protect yourself from the dangerous diseases that these insects carry!
