Overview

Tick-borne meningoencephalitis or, more commonly referred to as, Tick-borne encephalitis, is a tick-borne viral infection of the central nervous system affecting humans as well as most other mammals. The virus can infect the brain (encephalitis), the membrane that surrounds the brain and spinal cord (meningitis) or both (meningoencephalitis). It is transmitted by the bite of infected deer ticks or (rarely) through the non-pasteurized milk of infected cows. Sexual transmission has been documented in mice with vertical transmission to progeny. Sexual transmission with humans has never been documented. Tick-borne encephalitis is incurable once it manifests, but the virus can be inactivated and prevented by vaccination. [1]

Prevention

Tick-borne encephalitis prevention strategies are based on avoiding potential, infected, tick bites. Avoiding tick bites may be accomplished through limited exposure to endemic areas. However if it is impossible or impractical to avoid these areas, several preventative strategies may be implemented. These strategies are indicated under the Prevention title below. Other prevention strategies include a proper removal of the tick. This process is also outlined below under the title, the best way to remove a tick.
