Tick-borne Encephalitis Virus (TBEV)

Tick-borne encephalitis virus (TBEV) is a positive-sense, single-stranded RNA virus belonging to the genus *Flavivirus*. It is the causative agent of tick-borne encephalitis (TBE), a viral infectious disease that primarily affects the central nervous system and can lead to meningitis, encephalitis, or meningoencephalitis. Transmission occurs primarily through tick bites and, less commonly, through consumption of unpasteurized dairy products. Key proteins include the envelope protein (E) which mediates cell entry and induces protective immunity, capsid protein (C) which forms the nucleocapsid, and non-structural proteins (NS3, NS5) involved in replication. There is no specific antiviral treatment; management focuses on supportive care. Vaccination is available for prevention.
