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.

Equine Infectious Anaemia Nov. 2, 2018 Bonnyville Alberta Ongoing

An Equine Infectious Anemia (EIA)-affected premises has been identified in the province of Alberta. Please note that the following information is in addition to what the Canadian Food Inspection Agency (CFIA) already communicates to stakeholders which includes:

• notification to the relevant provincial veterinary service of any newly affected premises

• monthly federally reportable disease updates on the CFIA website (10th of each month), which includes the number of affected premises as well as individual animal cases

• communications with the owners or persons directly involved in the case, as outlined in the current EIA program policy

On November 2, 2018, a positive EIA result was confirmed by the CFIA’s national reference laboratory for a horse on a premises in the municipal district of Bonnyville, Alberta. The horse had been sampled by an accredited veterinarian to comply with U.S. import conditions. No clinical signs of disease were noted at the time of sampling. A CFIA investigation is underway and as per program policy, a quarantine has been placed on the infected animal and its on-premises contact animals.

Equine Herpes Virus-1 Jan. 24, 2019 Haldimand County, Ontario Horses have been euthanized

On January 18, 2019 the Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA) was notified of two cases of equine herpes viral abortion caused by equine herpesvirus-1 (EHV-1) at a farm in Haldimand County. The two mares aborted during their 9th and 10th month of pregnancy. One week prior to the abortions, two horses on the same farm suddenly developed neurological signs consistent with the neurological form of EHV-1 infection, also known as equine herpes myeloencephalopathy (EHM).

These horses were euthanized and no further diagnostic testing was performed. The farm owner has voluntarily placed the premises under quarantine to reduce the risk of disease transmission. In Ontario EHV-1 infection is immediately notifiable by laboratories to OMAFRA under the Animal Health Act. Attending veterinarians concerned about cases of equine herpesvirus-1 infection may contact an OMAFRA veterinarian through the Agricultural Information Contact Centre at 1-877-424-1300.
