The Welsh Cross from Santa Barbara County departed Permanent Barn 2 on March 10th from the competition. The gelding began displaying neurologic signs 10 days later.
This strain is responsible for the more common respiratory EHV-1 cases. A small percentage of non-neuropathogenic infected horses can display neurologic signs. Those are classified as equine herpes myeloencephalopathy cases which are a reportable condition in California.
We recently told you about a warmblood stallion that is also affected with the virus in the county. California Department of Food and Agriculture’s epidemiologic investigation indicates the stallion departed from HITS Tent 29 on March 15th.
Both horses are quarantined and are under veterinary care.
If your horse could have been exposed, veterinarians recommend that it should be isolated and its temperature monitored twice daily for 14 days post potential exposure date.
A third horse in California died earlier this month at Santa Anita from EHV-1. There have been no other reported cases at the track.
