West Nile is a virus carried by mosquitoes that feed on an infected bird. The mosquito can then infect people, horses and many types of birds. Scientists do not believe the virus is spread from person to person or from animal to person.Although the virus does not affect most humans and horses, Washington State Department of Agriculture considers this to be a serious threat to the state. Agency staff and are working with local, state and federal agencies to minimize the threat.
Equine encephalitis is a reportable disease.

Protecting horses and other equines
The virus affects horses, mules, donkeys and other equines much more often than other animals. Most horses infected with the virus; do not become ill and show no symptoms at all; about one-third of horses that become ill; die. Those that do become ill, show signs such as: loss of appetite, loss of coordination, confusion, fever, stiffness, muscle tremors, and weakness.
You should talk to your veterinarian about the West Nile Virus vaccine. The vaccine requires two doses three to six weeks apart, and immunity may not be achieved until up to six weeks after the second dose. An annual booster should be given a few weeks to a month prior to the start of the mosquito season in your area.
To minimize the threat of West Nile virus, control mosquito populations and prevent exposure to mosquitoes.
