Just got wind of Sonoma confirming 5 EHV-1 cases yesterday with at least 1 death. Had a horse that was going to travel there this week but we pulled out. Does anyone have information or updates on this outbreak???
The most helpful information I found was on the CDFA site (pro tip - just Google CDFA EHV) - https://www.cdfa.ca.gov/ahfss/animal_health/equine_herpes_virus.html
Blenheim set out an email before there was even info on the CDFA site stating no horses to go to Oaks from Sonoma and all horses at Oaks this week to have temperatures monitored twice a day with a log posted outside each stall. From link in email - https://4k9tr.r.a.d.sendibm1.com/mk/mr/LwB9gRLMT2ia8uKlH31gr1TVUxIwpUC4481dhQDjtXe3v3_Q2rfBXA8rfOVrbWZIja4LXuSfTMNenafXC7d-oocUH-oQb9z48zuMqFkwwQXMvIY
And there was something on Plaid Horse. That is the only place I saw the death mentioned, though it did not sound good for one of the horses mentioned on the CDFA site. https://www.theplaidhorse.com/2021/07/25/ehv-1-outbreak-at-sonoma-horsepark/
An email was sent out this morning to USEF members. Here is an excerpt:
The U.S. Equestrian Federation has been in contact with competition organizers and the California Department of Food and Agriculture Animal Health Branch regarding a case of equine herpesvirus myeloencephalopathy (EHM) confirmed positive secondary to equine herpesvirus-1 (EHV-1). The horse, a six-year-old Warmblood mare displaying neurological signs beginning July 23 was confirmed positive July 24 for EHM secondary to EHV-1 and has been euthanized. She attended a show at Sonoma Horse Park in Petaluma, Calif., from 7/19-7/24 but did not compete.
Anyone know what barn the 19 exposed horses are being kept at?
I heard through the grapevine that the home barn was stabled in Rancho Murieta where Let’s Show and Sac International holds their shows. Apparently they are also having a dressage show there this week too? It looks like the exposed horses have been moved to Davis though.
I think the dressage show was moved as a result of EHV cases.
CDFA lists the total number of cases in this incident as one confirmed with equine herpesvirus myeloencephalopathy (EHM, which means EHV-1 positive with neurologic signs); one new confirmed case of EHV-1 (fever and/or edema only) that has subsequently retested negative; and one confirmed case that was euthanized. All other affected horses are under veterinary care.
