[Incognito]

On August 23, 2011, a 15 year old Oldenburg mare from Sonoma County was confirmed positive for the neuropathogenic strain of Equine Herpes Virus-1. The mare is isolated, quarantined and undergoing treatment at a veterinary referral hospital. The premises of origin is under veterinary observation and the potentially exposed horses temperatures are being monitored twice daily. Epidemiologic investigation conducted by CDFA reveals minimal disease risk based on lack of animal movement on and off the affected premises. The investigation has determined the positive horse has no direct link to the May 2011 outbreak of EHV-1 in cutting horses which resulted in 22 positive confirmed equine cases in California. CDFA staff will continue to monitor the situation to ensure disease control.
