Ticks are found everywhere, not only in the forest. They can also live in parks and even in cities. In Estonia, 4−5 species of ticks have been identified, the most common of these being Ixodes persulcatus tick, or the taiga tick, and Ixodes ricinus, known as the sheep tick or castor bean tick. The tick season usually starts in April and lasts till October.

The most dangerous among these is tickborne viral encephalitis. A wide-spread and well-known tickborne infection is the Lyme disease (borrealis). Ticks may also be vectors for some other, less-spread diseases, such as Ehrlichiosis, Tularemia and Babesiosis.

The primary rule of removing a tick from your body is to be careful. Do not squeeze the tick, because you may secrete the ticks saliva into the bitten area and with this, the pathogen as well. Tweezers should be used to grip the neck of the tick and to pull it out in a sudden twisting motion. If the head of the tick remains in the skin, leave it there, the body will push it out on its own.

Symptoms can last up to 8 days and can be quite mild – some fever, headache, fatigue, muscle pain, nausea, and loss of appetite. If you have not been vaccinated, then you need to monitor yourself for at least a week. Getting a blood analysis is recommended two to three weeks after you have been bitten by a tick.

Approximately one-third of patients develop severe symptoms after the first phase of the illness where the virus causes meningitis (attacks the thin lining that surrounds the brain and the spinal cord) and / or encephalitis (swelling of the brain). Second phase symptoms include stiff neck, fever, headache, nausea, sensitivity to light, confusion, disorientation, drowsiness, behavioural changes, seizures and paralysis. Some patients may experience long-term complications such as memory loss, speech and language problems, mood disorders, epilepsy, fatigue, and motor skill difficulties.
