Tick-borne Encephalitis

Tick-borne encephalitis (TBE) virus has three subtypes: European, Siberian and Far Eastern. Infection can be fatal with the risk depending on the type of TBE. Travellers who spend time in regions where TBE is endemic – mainly forested areas of central and eastern Europe, Russia, northern China, and Mongolia – may be at risk. The highest risk is during the warmer months from April to November, especially when hiking or camping in areas below 1500m. Ticks climb onto grass and other vegetation then latch onto animals and humans as they pass by. TBE virus is transmitted to humans through the bite of infected tick of the Ixodes species. Ticks may breed around homes and in local parks too. Humans are often unaware that they have been bitten.
