EHM Advisory 2018-09-14 2018-09-14 EHM Advisory 2018-09-14 A Confirmed Case of Equine Herpes Myeloencephalopathy in Simcoe County The Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA) has been notified of a confirmed case of equine herpes myeloencephalopathy (EHM), caused by equine herpes virus 1 (EHV-1), in Simcoe County. The horse developed acute and severe neurological signs and was euthanized. Another horse that shared the paddock with the infected horse also developed neurological signs but is recovering. The farm owner has voluntarily placed the premises under a self-imposed quarantine to reduce the risk of viral spread. EHV-1 infection in horses can cause respiratory disease, abortion, neonatal foal death, and/or neurological disease. EHV-1 is not a federally reportable disease but is immediately notifiable by laboratories under the reporting regulation of the provincial Animal Health Act. Attending veterinarians suspicious of EHM should contact OMAFRA at Agricultural Information Contact Centre: 1-877-424-1300. Because infected horses may show no clinical signs, but still shed the virus, the temperature of suspect animals should be monitored twice daily for 14 - 21 days and any abnormalities discussed with a veterinarian. Neurological signs, if they develop, may include loss of balance, hind-limb weakness, recumbency, difficulty urinating, decreased tail tone and depression. It is important that a veterinarian assess suspect cases of EHM since it can be difficult to distinguish this from other serious neurological diseases this time of year, such as West Nile virus infection, Eastern equine encephalitis and rabies. EHV-1 is easily spread by nose-to-nose or close contact with an infectious horse, by sharing contaminated equipment including bits, buckets, and towels or by the clothing, hands or equipment of people who have recently had contact with an infectious horse. This highlights the need for routine biosecurity measures including hand hygiene and basic cleaning and disinfection practices, to be in place at all times to prevent a disease outbreak. Special attention should be given to cleaning and disinfecting trailers. Current EHV-1 vaccines may reduce viral shedding but are not protective against the neurological form of the disease. Implementing routine biosecurity practices is the best way to minimize viral spread. The best method of disease control is disease prevention.

Report of WNV cases in Saskatchewan

Eastern Equine Encephalitis Aug. 8, 2018 Haldimand County, ON Confirmed

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. Labaratory diagnostic testing confirmed infection with EEE virus. Private veterinarians have confirmed that three more horses have demonstrated acute onset of neurological disease within a 5 km radius of these two horses and two have been euthanized.
