Tick-borne encephalitis (TBE) is a viral infection spread by the bite of an infected tick. Eating or drinking raw (unpasteurised) milk or dairy products from infected animals (cows, goats and sheep) is also a risk. Ticks carrying TBE are found in forests, grasslands, moors and wooded areas (including urban parks) in many parts of Asia and Europe. Most people infected with TBE do not become seriously ill, but TBE can cause a severe, potentially life-threatening central nervous system illness. TBE vaccine is a private travel vaccine in the United Kingdom (UK) and is recommended for those visiting TBE affected areas, if their activities and/or job put them at increased risk or they will be living in a TBE endemic region.
