Viral Infections
Tick-borne encephalitis [en-sef-e-li-tis] (TBE) is a Flavivirus that has spread from central to north-west Europe. It is closely related to Russian spring-summer encephalitis (RSSE) and Louping-ill. The virus can be transmitted both transovarially (from the female tick through the egg to the next generation) and transstadially (through each stage of the tick’s life cycle). Infection may also occur following the consumption of raw milk from goats, sheep or cows. Transmission from an infected mother to her foetus can also occur.
