We used ELISA and PCR for laboratory verification of West Nile fever (MUC 4.2.3009-12). We analyzed serum and whole blood samples which had been sent to West Nile fever reference monitoring centre in 2018–2019. A total of 270 blood samples obtained from patients with presumed viral encephalitis of unknown etiology, acute respiratory viral infection, acute respiratory viral infection, meningitis, acute gastroenteritis were analyzed. Antibodies against WNV were detected in 193 (71,4 %) blood samples, while 146 samples were found to be capable of developing an immune response with viral RNA not being detected in them. Both WNV antibodies and viral RNA were detected in 47 (17,4 %) samples tested. WNV RNA was detected in only 14 (5,1 %) cases. Thus, laboratory confirmation of WNF was obtained in 76,6 % of cases (207 out of 270).
