Technical Abstract: West Nile virus (WNV) is a mosquito-borne member of the Flaviviridae family (genus Flavivirus) transmitted among bird populations by mosquitoes and incidentally infecting mammals. First recognized in the United States in 1999, WNV has spread across the United States in subsequent years. Numerous cases of WNV-induced non-suppurative encephalomyelitis have been documented in horses since 1999. Here we report on 4 cases of non-suppurative encephalomyelitis in reindeer (Rangifer tarandus) resulting from WNV infection. Clinical signs and lesions were similar to those described in horses; however, these represent the first known cases of clinical WNV infection in Cervidae.
