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.

Equine influenza virus, or EIV, is an extremely contagious respiratory disease or flu affecting horses, mules, and donkeys. EIV is characterized by fever, apathy, and lack of appetite, and causes respiratory symptoms such as coughing and nasal discharge. However, some horses infected with EIV have no observable signs of the virus. Left untreated, the virus can lead to secondary infections and pneumonia. In most cases, influenza is not fatal, however, horses with impaired immune function may be more susceptible to negative outcomes.

Neonatal maladjustment syndrome (NMS) - also referred to as dummy foal syndrome - is a condition that causes neurological symptoms in foals. This condition prevents the foal from performing normal behaviours, such as recognizing and feeding from the mare, standing and walking. Affected foals may appear lethargic, depressed, or display more serious clinical signs. NMS can be caused by oxygen and nutrient deprivation in the foal before birth. It may also be caused by a failure of placental hormones to drop following birth.
