The aim of the study was to analyze of tick-borne encephalitis (TBE) in the Warmia-Masuria province on the basis of serological testing of 878 patients with symptoms of neurological infections, diagnosed in 2006-2010 in the Voivodeship Sanitary-Epidemiological Station in Olsztyn. Specific IgM and IgG antibodies against the TBE virus were detected in serum and cerebrospinal fluid samples by ELISA method. Percentage of persons with serologically confirmed TBE was 15.5%. This confirms contact with TBE virus and its role as the suspected cause of neurological infections in patients in the Warmia-Masuria province.
