California officials confirm a new case of the equine herpes virus (EHV-1) at Burbank’s Los Angeles Equestrian Center.

Workers moved the infected horse to isolation Friday after if began running a fever. A second febrile horse tested negative for EHV-1.

The California Department of Food and Agriculture reports it is waiting on test results for a third quarantined horse after it started running a fever Sunday.

California officials released three barns – D, E, and F – from quarantine since they have not had a confirmed case of EHV-1.

The outbreak has affected 14 horses and precipitated the cancellation of the Pasadena Tournament of Roses 2016 Equifest. The event, scheduled for December 30, was to happen at LAEC. Organizers said all Equifest ticket purchasers will receive refunds.

EHV-1 can cause respiratory disease, abortion in mares, neonatal foal death, and neurological disease.

EHV-1 is highly contagious. It has an incubation period of 2 to 10 days. Respiratory shedding of the virus generally occurs for 7 to 10 days but may persist longer in infected horses.

Direct, horse-to-horse contact is a common route of transmission, but indirect transmission is also possible. It occurs when infectious materials are carried between infected and non-infected horses by people or inanimate objects such as buckets, tack, or trailers.

The source of infectious droplets is most often respiratory secretions.

Veterinarians recommend utilizing basic bio-security measures to help prevent the spread of the virus.
