The Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA) was notified of two confirmed cases of Eastern Equine Encephalitis (EEE) in Haldimand County, ON.
Both horses, from separate farms, were unvaccinated for EEE and had no history of travel. They were euthanized following the sudden onset and progression of neurological signs. Laboratory diagnostic testing confirmed infection with EEE virus.
Private veterinarians have confirmed that three more horses have demonstrated acute onset of neurological disease within a five kilometre radius of these two horses and two have been euthanized.
