AAEP Publishes Rotavirus Guidelines

Mar 21, 2019

The American Association of Equine Practitioners (AAEP) has published on its website comprehensive guidelines for the identification, management and prevention of rotavirus, a leading cause of diarrhea in foals up to six months of age at horse breeding centers worldwide. 

Published as a PDF file, the Rotavirus Guidelines document conveniently summarizes the disease’s clinical signs, risk factors, diagnostic methods, control measures, biosecurity issues and other management protocols. 

The guidelines were created at the request of the AAEP’s Infectious Disease Committee by Roberta Dwyer, DVM, MS, DACVPM, equine extension veterinarian and professor at the University of Kentucky; and Ashley Whitehead, DVM, BSc, DVSc, DACVIM, senior instructor in equine clinical sciences at the University of Calgary. Drafted guidelines were then reviewed and approved by the committee and the AAEP’s board of directors.

“Foal diarrhea remains a disease of enormous significance to the horse industry,” said Dr. Dwyer. “Rotavirus is one of the most common pathogens in major breeding areas worldwide. Early recognition, diagnosis, treatment and biosecurity in cases of foal diarrhea are key to minimizing disease impacts to breeding farms.”

The American Association of Equine Practitioners, headquartered in Lexington, Ky., was founded in 1954 as a non-profit organization dedicated to the health and welfare of the horse. Currently, AAEP reaches more than 5 million horse owners through its over 9,000 members worldwide and is actively involved in ethics issues, practice management, research and continuing education in the equine veterinary profession and horse industry.
