2013 EHV-1 Tracker Map

Equine herpesvirus-1 (EHV-1) is a highly contagious disease that affects horses and camelids and is commonly referred to as rhinopneumonitis or “rhino” in its respiratory form. EHV-1 is passed horse to horse via aerosol transmission (when affected animals sneeze or cough) and contact with nasal secretions.

The virus can cause epidemic abortion in mares, the birth of nonviable foals, or a sporadic neurologic form of the disease called equine herpesvirus myeloencephalopathy (EHM). The Horse’s official 2013 EHV-1 Tracker offers the most up-to-date and accurate information about reported EHV-1 cases throughout the United States and Canada.
