Tick-borne encephalitis (TBE) is an infection spread by tick bites. Ticks that spread it are found in parts of Europe and Asia, and some parts of the UK.
Ticks live in forests and grassy areas. You're more at risk of being bitten if you do activities such as hiking and camping.
Not all ticks spread TBE. Even if you're bitten, the risk of getting seriously ill is low.
