Five additional horses that are linked to the HITS Show in Ocala have tested positive for EHV-1 wild type. One is located at Redfield Farm in Ocala, four are located at Miles Away Farm in Loxahatchee, Florida. One horse not believed to be linked with any of the HITS-associated quarantined premises has also been positive for EHV-1. This horse is located at Tequestrian Farm in Wellington, Florida.
