The Massachusetts Farm Bureau has been advised that there is a single confirmed case of equine enteric corona virus in a horse that recently attended a show at the Eastern States Exposition. The affected horse was on the Big E grounds during the Quarter Horse show that ended on July 22, 2018.
There are rumors of additional horses that attended the same show with similar clinical signs that have not been confirmed. Clinical signs include fever, anorexia, lethargy, and change in normal feces (not necessarily diarrhea). The virus is transmitted by the fecal/oral route.
There have been additional equine events held at the Big E venue since July 22, 2018. Due to the manner of transmission, horses that attended the Quarter Horse show as well as more recent events on the grounds must be considered potentially exposed. Management at the Big E has been notified and is instituting additional cleaning and disinfection protocols.
As a precaution all horses returning from any shows should be isolated from other horses at the home farm. Take care of the home population first and the show string last. Separate equipment including brushes, manure forks, and muck buckets should be used. Twice daily temperature checks on the show horses are recommended. Any temperature above 102 degrees or more than one degree above a horse’s normal temperature should be evaluated by a veterinarian.
Since most diseases present with an increase in temperature as a first sign, temperature elevation can be considered an early warning system for many infectious and contagious diseases
