Equine coronavirus is an RNA virus that causes gastrointestinal disease in horses. Although it is also a type of coronavirus, Equine Coronavirus is NOT the same as COVID-19.

Incubation: The incubation period is the time from exposure to the virus to when a horse shows clinical signs of infection. The incubation period for Equine Coronavirus is two to four days.

Transmission: Transmission occurs when a horse ingests an infected horse’s feces or otherwise comes into contact with contaminated surfaces.

Shedding Period: The shedding period for Equine Coronavirus is unknown.

Clinical Signs: Signs include fever, colic, diarrhea, and a low white blood cell count. In rare cases, dehydration, neurologic signs, recumbency, and death may also occur.

Diagnostic Testing: Diagnosis can occur when clinical signs are presented or if PCR testing is used to detect Equine Coronavirus in feces.
Treatment: Supportive care is the primary treatment, however, severe cases may need IV fluids.

Prevention: There is no vaccine available for Equine Coronavirus. Keeping areas cleaned and disinfected is the best way to prevent the disease and spread. It is important to remember to clean first and remove all organic material before disinfecting.

Prognosis: The infection rate can be as high as 85% for horses exposed to Equine Coronavirus, but most horses will never show signs. Mortality is low but can occur in more severe cases.
