Assessment of the potential effect of the implementation of serological testing tick-borne encephalitis on the detection of this disease on areas considered as non-endemic in Poland - preliminary report.

1. Detection of the presence of antibodies against TBE in samples of patients with meningitis reported as other neuroinfections indicates the etiology of TBE. 2. The number of TBE cases may be undiagnosed, and thus underestimated due to the failure to perform serological tests for TBE in areas considered non-endemic. 3. The diagnosis and reporting of neuroinfections caused by the TBE virus is essential for a proper risk assessment and in promoting prophylaxis in the form of vaccinations. 4. Preliminary results of the research indicate the need for their continuation in all voivodeships.
