The six stables currently quarantined for equine herpesvirus-1 (EHV-1) in Delaware could be released later this week, according to a statement released by State Veterinarian Sara Busch, DVM. The hold orders on these farms could be lifted Feb. 7.

One horse died Jan. 17 after displaying neurologic signs. This horse was confirmed positive for EHV-1 via polymerase chain reaction (PCR) tests on nasal swab samples. Delaware officials performed a trace-back and identified nine animals exposed to the affected horse. The affected horse’s home barn and five additional facilities are under Delaware Department of Agriculture quarantine orders.

All of these farms are within Kent County. The affected horse lived in the Felton/Frederica area. Two of the quarantined barns are in Clayton. The others are in Dover, Hartley, and Camden.

Temperatures of quarantined horses are being monitored twice daily. Any horse with a temperature greater than 102°F or displaying neurologic signs must be isolated and reported to the State Veterinarian’s office.

As of Jan. 29 there were no new or suspect cases of EHV-1 in Delaware, according to Busch.

Equine herpesvirus-1 is a form of herpesvirus that can cause fevers and neurologic signs that range from incoordination and weakness in the hind limbs to paralysis. Precautions are necessary because EHV-1 is highly contagious and can spread through the air. It can also be passed on shared tack and barn equipment, as well as human hands and clothing, making tight biosecurity essential to stop it from spreading.
