Clinical Signs: Fever, Neurological Signs, Recumbency; Confirmation Date: 6/16/2020; Horse Status: Euthanized; Vaccination Status: Vaccinated;
Notes:The infected horse had been treated in isolation at the clinic for a few days before acutely showing neurologic signs. The horse was subsequently euthanized. The clinic practiced approved biosecurity protocol at all times during the horse’s stay. No other horses at the clinic were exposed and the clinic remains open to patients. The horse originated from a private farm in Fauquier County. The farm and the neighboring farm, that shares a fence line, have both been placed under quarantine. All exposed horses on the farms are being monitored twice daily for fever (temperature over 101.5 0 F) and other clinical signs. None of the horses on either property are showing signs of illness. No trail riding is conducted through either property that could have exposed other horses. No additional Virginia horses have been exposed as none of the horses from either property had contact with other horses in the two weeks leading up to the illness in the index horse.
