On December 31, 2016 a horse in barn #36 spiked a fever with clinical signs of mild hind leg deficits and nystagmus. The horse was placed in quarantined isolation and the barn was quarantined. Blood and nasal samples sent to the LA Animal Disease Diagnostic Lab tested PCR positive today for EHV-1 non-neuropathogenic or wild type strain. The confirmed EHV-1 wild strain case and barn #36 have been placed under quarantine for 2 weeks. The confirmed EHV-1 neuropathogenic case from barn #14 is under continued quarantine isolation and is asymptomatic at this time. Barn #14 is under continued quarantine with no new febrile cases. All horses under quarantine are having their temperatures monitored twice daily and enhanced biosecurity measures remain in place.
