Field evaluation of commercial Immunoglobulin M antibody capture ELISA diagnostic tests for the detection of Japanese encephalitis virus infection among encephalitis patients in Nepal

Both commercial kits had good predictive values when single serum samples from encephalitis cases were tested in a national laboratory. Either kit can be used in similar JE-endemic settings where co-transmission of dengue virus, a flavivirus which has strong cross-reactivity with JE, is limited. These results can inform decisions by countries and the World Health Organization laboratory networks on national-level use of these kits for JE surveillance.
