An infectious disease characterized by central nervous system (CNS) involvement caused by the TBE virus (TBEV) and transmitted to humans principally by the bite of ticks from the <i>Ixodes</i> genus. The symptomatology is often biphasic, with the initial phase being associated with a nonspecific febrile illness and the second phase with meningitis, meningoencephalitis or meningoencephalomyelitis.
