The Tahyna virus occurs only in Europe and non-European areas of the former USSR . The infection was also detected in Germany (Upper Rhine Graben), Austria , Italy and France through detection of the specific antibodies . An acute Tahyna virus infection shows only very unspecific symptoms, flu-like and with one to two day fever , respiratory infection , rarely meningitis , rheumatic complaints, myalgia and possibly encephalitis .
Tahyna virus disease is usually undiagnosed as it often turns out to be what is known as the mundane summer flu. One reason for the lack of epidemiological data in Europe is, in addition to the difficulty in verifying the virus diagnosis, the fact that CNS involvement (meningitis, encephalitis), as with TBE, only occurs after a symptom-free interval and then does not occur with the "survived" virus disease beforehand Is associated.
