CDFA Equine Herpes Virus found in San Diego County March 2013
March 19, 2013: A Warmblood stallion in San Diego County displaying mild neurologic signs has been confirmed positive for the non-neuropathogenic strain of Equine Herpesvirus -1 (EHV-1). This strain of virus is responsible for the more common respiratory EHV-1 cases. A small percentage of non-neuropathogenic EHV-1 infected horses can display neurologic signs and are classified as equine herpes myeloencephalopathy cases which are a reportable condition in California. The positive horse has been quarantined and is under veterinary care. CDFA is working to contact exposed horse owners and recommend isolation, twice daily temperature monitoring and implementation of proper biosecurity.
Recommendations for Participants at Equine Events
CDFA Animal Health Officials are continually monitoring for Equine Herpes Virus-1 cases. CDFA has no reports of EHV-1 cases in the state at this time. CDFA has no recommendations for the cancellation of any equine event. CDFA reminds horse owners traveling with horses to participate in an equine event, that there is always disease risk when horses of unknown health status are commingled for a show or competition. CDFA strongly recommends that horse owners practice proper biosecurity when attending an equine event. Compliance with basic biosecurity practices is an important factor in reducing risk of exposure to all contagious equine diseases. Basic biosecurity measures to follow to decrease potential disease spread at equine events include:
· Limit horse-to-horse contact.
· Limit horse-to-human-to-horse contact.
· Avoid use of communal water sources.
· Avoid sharing of equipment unless thoroughly cleaned and disinfected between uses.
· Monitor your horse for clinical signs of disease and report any temperature over 102°F to a veterinarian.
