California State Veterinarian Annette Jones, DVM, released a letter on March 3, 2022, urging organizers and owners to postpone equine events and nonessential transportation of horses. The recommendation comes in response to the current equine herpesvirus myeloencephalopathy (EHM) cases in the state.
In the letter, Jones wrote, “To reduce disease spread, the California State Veterinarian recommends that all hunter/jumper events (the most affected group) be postponed for the next 28 days, all equine events be postponed for the next 14 days, and all nonessential horse movements postponed for at least 14 days.”
The state has reported recent cases related to the outbreak in Orange, Riverside, and San Mateo counties.
