The horses were located in Moravia (Cayuga County), Avon (Livingston County), Altmar (Oswego County), Rensselaer Falls (St. Lawrence County) and Macedon (Wayne County). Three horses are alive and two were euthanized.

New Jersey Neurologic Herpesvirus

The New Jersey Department of Agriculture confirmed equine eerpesvirus myeloencephalitis (EHM) in Warren County, New Jersey. The 25-year-old Quarter Horse was euthanized on November 2, 2017. There are other horses on the premises that were exposed to the affected horse as well as other horses at a New Jersey horse show that were potentially exposed. 

Biosecurity measures are in effect at the home premises and will be in place for the duration of the 21-day quarantine. Additionally, all the horses on the quarantined premises will have temperatures checked twice daily in order to confirm the virus is not spreading. 

Currently, one of the exposed horses at the home premises has demonstrated an increase in temperature. 

Tracebacks are currently being performed for all potentially exposed horses.
