Equine Mosquito-Borne Diseases: Eastern Equine Encephalitis and West Nile Virus
West Nile Virus (WNV) Eastern Equine Encephalitis (EEE) are viruses that can cause fatal neurologic disease in horses. The viruses are carried in the bird population and spread by mosquitoes. The mosquito bites an infected bird and then bites a horse transmitting the virus through the saliva. Occurrence is seasonal and coincides with the increased presence of mosquitoes in mid-August to late October. If suspected, these diseases must be reported immediately to the Canadian Food Inspection Agency under the Health of Animals Regulations. These viruses often produce neurological signs in the horse that are undistinguishable from rabies. Cases of equine EEE and WNV have been confirmed in 2012 in eastern and south-eastern United States, but no confirmed cases have been identified in Canada in 2012.
