Northwest Horse Owners Warned About Outbreak In Texas, Oklahoma

The Northwest rodeo community and horse owners are being warned of an outbreak of Equine Herpes Virus, better known as EHV, as well as Equine Herpes Myeloencephalopathy, EHM.  The horses associated with this out break participated in barrel racing and rodeo-type events down in Texas and Oklahoma.

Several cases of EHM have been confirmed in both Texas and Oklahoma, with numerous reports of additional cases and equine deaths pending investigation.  At this point, there have been no confirmed cases of EHV/EHM in Washington, Oregon or Idaho.

The three Northwest state departments of Ag says they are working with their counterparts down south to receive trace information.  This outbreak serves as a reminder of the potential disease risks associated with large equine events and stresses the importance of timely reporting of diseases and ensuring that movement requirements are followed, including veterinary inspection and health certificates prior to travel.

EHV Is Highly Contagious, But Can't Infect Humans

EHV is spread from horse to horse through contact with nasal discharge or spread as aerosol droplets.  Infected horses may not show clinical signs of the virus but may still act as carriers.   Horses can also contract the virus by coming into contact with contaminated surfaces such as stalls, water, feed, tack, and transport vehicles.  People can spread the virus from horse to horse by contaminated hands and clothing.  It is important for owners to watch for signs and symptoms and practice biosecurity measures.  Good biosecurity practices include extensive cleaning and disinfection of surfaces and equipment that come in contact with affected horses, and individuals who treat or come into contact with infected horses need to follow appropriate disinfection protocols when handling multiple horses.

EHV, while highly contagious to horses, but cannot infect humans.  In the event that your horse is showing symptoms, contact your local veterinarian.
