On February 27, 2018, the Virginia Department of Agriculture and Consumer Services (VDACS) placed the Hazelwild Farm in Fredericksburg under quarantine for equine herpesvirus myeloencephalopathy (EHM).
Utilizing separate biosecurity protocols, the farm immediately isolated a barn housing boarding horses from another barn that houses school horses. Since the quarantine began, four horses in the school barn have developed fevers and tested positive for equine herpesvirus type 1 (EHV-1), but no horses developed neurologic signs.
None of the boarding horses have tested positive for EHV-1.
On March 20, 2018, VDACS released the boarder barn from quarantine.
The barn housing school horses will remain under quarantine for 21 days after the last clinical case.
A second, unrelated farm in Powhatan was also placed under quarantine for EHM on February 27. The remaining horses at that farm showed no further signs of illness and that farm was released from quarantine on March 21.
