CDFA – Lastest West Nile Virus Activity in California – 2016

The first case of equine West Nile Virus has been confirmed for 2016. A thoroughbred mare met case definition with neurologic signs and a positive IgM Capture ELISA test for West Nile Virus. The positive horse is located in San Diego County. The unvaccinated five-year-old mare is alive and recovering slowly.

The CDFA continually monitors and investigates equine neurologic cases for the presence of West Nile Virus in California. As a reminder, timely and accurate reporting of equine West Nile Virus cases by veterinarians is a valuable component of arbovirus disease surveillance and helps to direct mosquito control efforts designed to prevent West Nile Virus infection in both horses and humans.
