Equine Herpesvirus Infection: Symptoms, Treatment & Prevention
Equine herpesvirus (EHV), or rhinopneumonitis, is a contagious infection that is endemic to horses worldwide. EHV may cause mild to severe symptoms that usually involve the upper respiratory tract. In rare cases, it may cause neurological symptoms, abortion or death. Horses can experience latent infections of EHV where the virus lives dormant without causing symptoms. There are nine known types of herpes viruses in horses, of which EHV-1 and EHV-4 are the most common. EHV-1 usually results in more severe symptoms but EHV-4 is more common.
