In a follow-up to a recent report concerning Equine Herpesvirus-1 (EHV-1) in horses in Los Angeles County, three additional horses were confirmed positive for the non-neuropathogenic strain of EHV-1 on the Los Angeles County index premises Friday.
A Equine Disease Communication Center (EDCC) alert notes two of the three affected horses display neurologic signs and the third horse is febrile and all three are in isolation. Two of these newly confirmed equine cases attended the Las Vegas horse show last week. At this time, no additional EHV-1 cases have been confirmed in horses that exhibited at the Las Vegas horse show on October 27 – 29, 2016.
Exposed horses on the Los Angeles index premises continue to have their temperatures monitored twice daily and enhanced biosecurity measures remain in place. CDFA Animal Health Branch veterinarians continue to monitor the quarantine and situation on-site and will provide additional updates as they become available.
