About Equine Coronavirus

Equine coronavirus (ECoV) is a highly infectious pathogen that impacts the enteric, or intestinal, system of horses, causing fever, lethargy, anorexia, and in more severe cases, colitis and endotoxemia.

Historically thought to only occur in foals, ECoV has been increasingly reported in adult horses. It is transmitted between horses through exposure to contaminated fecal material, and it is most commonly diagnosed in the winter. 

ECoV has a short incubation period between 48 and 72 hours. Clinical signs generally last for up to one week, but horses can shed the virus in their feces for up to 21 days.
