Important information for horse owners
Hi all – please encourage 4-H horse project youth, leaders, and parents to vaccinate 4-H project horses (ALL horses, actually) for West Nile Virus. Previously vaccinated horses need an annual booster in early spring to optimize protection for the coming mosquito season. Naïve horses need a series of two vaccines and will not achieve adequate protection until a week after the second injection, so time is of the essence.
WNV would be a great topic for educational posters! Comparing WA and US stats is enlightening—we often lead the country in the number of equine casesL. Here is where 2017 updates will be located: http://www.doh.wa.gov/DataandStatisticalReports/DiseasesandChronicConditions/WestNileVirus.
A WSU pub on WNV is at http://cru.cahe.wsu.edu/CEPublications/FS201E/FS201E.pdf.

It’s that time of year – when mosquitoes are out and the potential for West Nile Virus infections are here. Because Washington state lost a number of horses to this disease last year and it is preventable, we need to get the word out.
The Continuing Veterinary Medical Education Program and the Department of Veterinary Clinical Sciences is providing a FREE program to the public about West Nile Virus in Horses.
Dr. Jenifer Gold, faculty member in CVM, recorded ”West Nile Virus – It Hasn’t Gone Away!”
This presentation is for owners and veterinarians to understand what West Nile Virus is, the history of the disease and its spread across the United States. Discussion of the clinical signs includes videos. Treatment protocols will be reviewed and the importance of prevention are discussed.
Free public presentation can be viewed at (public link – no login required): https://apps.vetmed.wsu.edu/CVME/Content/Courses/public/WestNileVirus/owner.html
Veterinarians interested in receiving 1 CE credit, can register and pay a $50 course fee. To view the On-Demand Program on Equine West Nile Virus visit: https://apps.vetmed.wsu.edu/CVME/Event/Details/35
Thank you for getting the word out to your horse owners and veterinarians!

July 26, 2016 (LAST YEAR)
The Washington State Department of Agriculture (WSDA) is reporting that a two-year-old Andalusian mixed breed mare in Grandview is the first horse in Washington to contract West Nile virus this year. The horse was not vaccinated for the disease and is showing neurologic signs of the illness including stumbling and difficulties eating.
Washington had 36 confirmed cases of horses with West Nile virus last year, leading the nation with nearly 17% of confirmed equine cases. And this year, mosquitoes testing positive for West Nile virus have been trapped in Adams, Benton, Grant, Franklin and Yakima counties.
“It’s never too late to vaccinate your horse for West Nile virus,” said WSDA field veterinarian Dr. Thomas Gilliom. “We’ve had cooler days but when hot summer days return the risks of mosquito bites will increase.”
Spring is the best time to vaccinate horses against West Nile virus or obtain an annual booster shot. However, horses may still benefit from first-time vaccinations or an annual booster shot.
Besides vaccination, horse owners can take action to limit horse exposure to mosquitoes. For example, reduce or eliminate sources of stagnant or standing water, stable horses during peak mosquito periods (at dawn and dusk), use equine-approved mosquito repellants, place fans inside barns or stalls to maintain air movement, and avoid using incandescent bulbs inside stables at night.
Veterinarians who learn of potential West Nile virus cases in horses or other animals should contact the State Veterinarian’s Office at (360) 902-1878.
Visit the websites of the state Department of Agriculture, Department of Health, or the U.S. Department of Agriculture for more information.
