Officials at the California Department of Food and Agriculture (CDFA) have released a Ventura County boarding facility from quarantine for equine herpesvirus-1 (EHV-1, non-neuropathic strain) as a result of no additional cases being reported among the 32 horses exposed there.

The index case, a 13-year-old Quarter Horse mare, which began showing clinical signs around Nov. 23, remains under quarantine at a veterinary hospital, and will be released from quarantine following its second negative test in seven days.

EHV 101

Herpesvirus is highly contagious among horses and can cause a variety of ailments in equids, including rhinopneumonitis (a respiratory disease usually found in young horses), abortion in broodmares, and equine herpesvirus myeloencephalitis (EHM, the neurologic form).

In many horses, the first or only sign of EHV-1 infection is fever, which can go undetected. In addition to fever, other common signs of EHV-1 infection in young horses include cough, decreased appetite, depression, and a nasal discharge. Pregnant mares typically show no signs of infection before they abort, and abortions usually occur late in gestation (around eight months) but can be earlier. Abortions can occur anywhere from two weeks to several months following infection with EHV-1
