Tick-borne Encephalitis is a viral infection that is transmitted by ticks. It is also called Frühsommer meningoenzephalitis (FSME).
Infection takes place immediately after the bite of a larva (0.5-1 mm), nymph (1-1.5 mm) or adult tick (3-10 mm). In other words, quick removal of ticks will not prevent infection.
In rare cases, infection can take place via ingestion of unpasteurised milk(products).
Disease symptoms (fever, fatigue, headache) can occur 3 to 28 days after the infection.
The disease usually causes mild symptoms. Sometimes neurological symptoms can occur, which can result in permanent disability or even death. A variant of the disease with a higher mortality rate is found in the former USSR, particularly in Siberia.
There is no specific treatment. A person who has had this disease becomes immune to it.
