Western equine encepahilitis virus (WEEV), CO921356 was isolated in Vero cells from a pool of Culex tarsalis (C. tarsalis) mosquitoes collected in Larimer City, Colorado, USA on July 30, 1992. The complete genome sequence of WEEV, CO921356 has been determined (GenBank: KJ554979).

WEEV is a mosquito-borne alphavirus that causes potentially fatal infections in horses and humans. Survivors of western equine encephailitis (WEE) often suffer permanent neurological sequelae. WEEV circulates enzootically among passerine birds and is transmitted primarily by C. tarsalis, with mammals participating in a secondary cycle. Humans and horses do not appear to be amplifying hosts.

WEEV is the descendent of an ancient recombination event between Sindbis virus-like and eastern equine encephalitis virus-like progenitors. There were widespread outbreaks of WEE in western North America in the 1930s through 1950s, but the incidence of the disease has decreased dramatically in recent decades. This reduction in disease incidence has been accompanied by a decline in the frequency of virus detection in mosquito surveillance programs.

Each vial contains approximately 1 mL of cell lysate and supernatant from Aedes albopictus mosquito larval epithelial cells (clone C6/36; ATCC ® CRL-1660™) infected with WEEV, CO921356.
