California officials report a Quarter Horse gelding tested positive for the non-neuropathogenic strain of the equine herpes virus (EHV-1).
The barrel racer, originating from San Luis Obispo County, displayed symptoms including mild hind limb ataxia. The 7-year-old is being cared for by veterinarians in Santa Barbara. An epidemiological investigation has been initiated, and owners with potentially exposed horses will be contacted, according to the state.
EHV-1 may lie dormant for long periods of time and then re-activate during a period of stress, which can result in clinical disease.
· Limit horse-to-horse contact.
· Limit horse-to-human-to-horse contact.
· Avoid the 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.
Last week, a Virginia horse was euthanized due to neurologic EHV-1.
