Notes: A horse with neurological signs was reported by a private veterinary practitioner in Marion County, on March 1, 2021. The horse subsequently tested positive for the Equine Herpes Virus (EHV-1), neurotrophic strain. As of March 3, 2021, the affected horse continues to be treated in a separate isolation facility. No additional EHV-1 cases have been detected. The Division of Animal Industry placed the premises under quarantine and immediately began a disease investigation. Additional movement requirements or restrictions have not been imposed by Florida or any other states at this time. We are advising horse owners and trainers to contact the venue of destination for any additional requirements prior to travel. However, in light of the recent EHV-1 outbreak in Europe, we are encouraging all facilities to isolate horses importing into Florida from the affected regions in Europe and enact strict biosecurity measures to include monitoring the horse’s health and taking temperatures twice per day for at least 14 days. We are asking all those in the equine community to practice prudent biosecurity on their farm and to report any suspected cases of EHV-1. For reporting, call (850) 410-0900 Monday through Friday 8:00 a.m. – 5:00 p.m. and 1-800-342-5869 after hours and weekends or email [email protected]. The Florida Department of Agriculture and Consumer Services will continue to work with the affected premises management, owners, and veterinarians to ensure proper safeguards are taken to prevent further spread of the disease.
