With the arrival of spring, many are beginning to go to nature. The main problem, which will face — mites, which can be in last year's grass and bush, and open natural areas. What you need to do and what steps to take if you still tick bites you? These are questions we asked a leading dermatologist clinics "MedCenterService", PhD — Vorotnikova Irina V..
Irina V., explain what the tick-borne encephalitis?
Tick-borne encephalitis — a viral disease of man, characterized by fever, intoxication and frequent lesion of the central nervous system.
Who is encephalitis?
Human infection may occur at crushing and rubbing stuck tick, by eating infected raw goat and cow milk. Infection can also occur without a visit to the forest — mite can be brought out of the forest with branches, for pet hair. If the infection is transmitted through the milk (some experts even allocate a route of infection and disease in the form of a single infection), the virus first enters into all the internal organs, causing the first wave of fever, then, when the virus reaches its final destination, central nervous system — the second wave of fever. Upon infection, the bite is developing another form of the disease, characterized by only one wave of fever, caused by the penetration of the virus in the brain and spinal cord and inflammation in these organs (actually encephalitis).
Tell me, what are the symptoms of tick-borne etsefalita know?
After being bitten by an infected tick, tick-borne encephalitis virus multiplies in the site of the bite. In the bite no change. After the virus enters the blood and lymph nodes and begins to multiply in the cells lining blood vessels. When there is a mass replication of the virus, symptoms that are similar to the symptoms of grippa.U most cases, the symptoms of tick-borne encephalitis occur in the second week after the tick bite. However, the incubation period can last from 2 to 21 days. But note, the infection may be asymptomatic. In such cases, encephalitis can only be determined by analyzes. The state of health does not change, the person feels healthy. In the blood, there are antibodies to the virus of tick-borne encephalitis, which suggests that he was exposed to the virus. Several distinct forms of tick-borne encephalitis
- poliomieliticheskuyu (менингоэнцефаломиелитеческая).
All forms begin acutely with chills, fever up to 38-40? body aches. Prodromal period or not it is short and lasts for 1-2 days appears malaise.
As you can tell whether there has been infected with tick-borne encephalitis?
Tick-borne encephalitis can be suspected on the basis of: the epidemic data (visit the forest, a tick bite), clinical data (high fever, meningeal syndrome, focal symptoms). Tick-borne encephalitis necessarily require laboratory confirmation. All patients with tick-borne encephalitis it is necessary to examine tick Lyme disease, because possible co-infection with both infections. To do this, use the following tests:
- IgM to the tick-borne encephalitis — a positive result means that a person recently infected with tick-borne encephalitis virus.
- IgG antibodies to tick-borne encephalitis — G antibodies appear later than M. Persist in the blood for life after suffering a tick-borne encephalitis. Responsible for immunity. Development of IgG is the major purpose of a vaccine against tick-borne encephalitis. The presence of antibodies in blood, and G and M, indicates ongoing infection. If you are determined only by IG — it is later date or the result of disease or vaccination.
- Antibodies to the pathogen borreliosis.
- Antibodies to Borrell.
- PCR on blood borne encephalitis — detects the presence of the virus in the blood.
Upon detection of tick it is necessary to remove (drop on the parasite oil or alcohol, wait 20 minutes, then take a lower tabs thread into a loop, slightly tighten and smooth rocking motion slowly pull the tick up, as it is possible to try to make a pair of tweezers). Remote mite better placed in a jar and drop off to the hospital, where it is possible to determine this was a tick is infected or not. Mites, due to their physiological characteristics, after sucking the skin does not immediately begin to feed on blood, so when their rapid detection and removal decreases the risk of being infected. If you can not remove the tick, it is necessary to urgently appeal to the medical center, where its carefully remove and recommend preventive treatment. Within 30 days after the bite should be seen by a doctor.
Irina V., what advice can you give to people who will spend a lot of time outdoors?
The basic rule is, of course, for the clothes. Properly dressed, you will be able to periodically remove ticks from clothing. It is better to avoid dark colored clothing, as ticks harder to see on a dark background. Need to fill in outerwear pants and shorts — in socks if no hood, you definitely need a hat. Preferably every 15 minutes to inspect the clothes, looking at the head and body, especially the waist up, ticks often attach themselves there.
