- Abstract
West Nile virus (WNV) infection usually causes mild febrile illness, but in a small proportion of patients it can lead to encephalitis. Epidemiological studies of WNV indicate fast spread of infection worldwide and in Europe, but there have been no comprehensive studies of WNV infection among encephalitis patients in Poland. Here we present the results of WN V RNA and anti-WN V testing in serum and cerebrospinal fluid (CSF) samples in 80 patients with the clinical diagnosis of viral encephalitis. WN V RNA was not detected in any of the analyzed samples. Anti-WN V IgG and IgM were not present in CSF in any of the investigated patients, but anti-WN V IgM were unexpectedly detected in serum of 14 subjects. The latter represented false positive results are probably related to cross reactivity of antibodies. Although there was no evidence of WNV infection in any of our patients, epidemiological situation in the neighbouring countries warrants vigilance and appropriate measures, including introduction of specific diagnostic tools into clinical practice, seem necessary.
