EHV-1: Multi-Site Outbreak

At a 2007 seminar on equine herpesvirus, Maureen Long, DVM, PhD, Dipl. ACVIM, associate professor in the department of infectious diseases and pathology at the University of Florida, discussed her experiences with a multi-site outbreak of neurologic equine herpesvirus in Florida.

“The state treated this as if it were a response to a hurricane, setting up a state incident command post,” Long said. “Thirteen infected horses shut down the industry,” she said. “There were seven horses with neurologic signs, and six horses died.
