FIRST CASE OF EQUINE WEST NILE VIRUS IN CALIFORNIA IN 2007
CDFA
Release #07-019
Horse owners urged to maintain vaccinations
SACRAMENTO February 21, 2007 The first case of equine West Nile Virus in 2007 has been reported in California. A horse in Sonoma County has been diagnosed with the disease. The detection serves as a reminder to horse owners to make sure their animals are vaccinated. Last year, 58 horses in the state were known to have contracted the disease, with 24 deaths. In the great majority of those cases the horses were either not vaccinated or vaccinated improperly.

"Outbreaks of West Nile virus are expected to continue this year," said California State Veterinarian Dr. Richard Breitmeyer. "Horse owners should contact their veterinarians as soon as possible to ensure current vaccination status, so that horses will have maximum protection against the disease."

Signs of West Nile virus include stumbling, staggering, wobbling, weakness, muscle twitching and inability to stand. Horses contract the disease from carrier mosquitoes and are not contagious to other horses or people. Not every horse exposed to the virus will die.

CDFA is collaborating with state, federal and local agencies to detect and respond to the disease in California. CDFA is distributing a video public service announcement about West Nile virus and has taken a public education program directly to the equine community over the last several years, including tips on mosquito control.
