TBE is a viral infection usually transmitted through the bite of an infected tick that exists in parts of central, eastern and northern Europe across Russia to parts of eastern Asia predominantly at altitudes lower than 1,500m
Tick-borne encephalitis (TBE) is a viral infection usually transmitted through the bite of an infected tick. The disease occurs in parts of central, northern and Eastern Europe, Siberia and parts of Asia. Ticks are found on forest fringes within adjacent grassland, forest glades, riverside meadows and marshland, forest plantations with brushwood and shrubbery. Ticks can also be found in parks and gardens.
Travellers to areas where TBE occurs may be at risk when walking, camping or working in woodland. In Europe, spring and summer are generally higher risk, but seasons vary according to location. Since 2011, six confirmed cases of TBE have been reported in the UK. All had history of travel to the TBE endemic areas of Europe.
Typically, the disease occurs in two stages: a mild flu-like illness and a potentially serious infection of the central nervous system (brain and spinal cord). TBE is rarely fatal in Europe: however in Asia it can be fatal in up to 20 percent of cases. Long-term neurological complications are common.
