Two horses at the University of Findlay have tested positive for equine herpes virus, though they are not showing symptoms, according to the Ohio Department of Agriculture.

Those horses have been isolated and the English Equestrian Farm is under quarantine, according to a UF press release. The quarantine will last at least four weeks.

Classes are continuing as usual.

Equine herpes can be spread through the air or contaminated clothing and equipment the ODA said.

The virus can affect horses in three ways: rhinopneumonitis (a respiratory disease of mostly young horses), abortions in pregnant mares, and the neurologic disease EHV-1 myeloencephalopathy, which can be fatal to horses.

All horses at the farm had been vaccinated against the virus.

To prevent the spread of the virus, strict regulations and biosecurity measures have been implemented, UF said. This protocol includes using proper disinfection and sanitizing practices and monitoring every horses temperature. Additional horses who have exhibited fevers at the English Farm have been tested, and to date, we have not received another positive test result.

The virus is not a threat to humans, the ODA said.

The Western Equestrian Farm is not under quarantine.
