On Aug. 11, a horse exhibiting neurologic signs was transported to the Marion duPont Scott Equine Medical Center in Leesburg, Va., from Culpeper, Va. The horse was immediately isolated from the hospital population without coming into contact with any other patients. The next day, the Virginia Department of Agriculture and Consumer Services’ Animal Health Lab in Warrenton confirmed a diagnosis of equine herpesvirus-1. The horse remains isolated while undergoing supportive care.
Then on Aug. 14, a second horse from the same farm in Culpeper County developed a fever and neurologic symptoms and was euthanized. VDACS’ Animal Health Lab confirmed a diagnosis of EHV-1. A third horse on the quarantined farm developed a fever and tested positive for the neuropath genic strain of EHV-1. The third horse has no other symptoms at this time.
The original farm is under quarantine until Sept. 6.
The Marion duPont Scott Equine Medical Center employed strict biosecurity measures and disinfection upon arrival and will continue to do so during the entirety of the horse’s hospitalization. The Marion duPont Scott Equine Medical Center is operating normally.
