July 18, 2023 (San Diego) – “Vesicular Stomatitis Virus (VSV), a viral disease that affects hooved mammals, has been confirmed in southern white rhinos living at the San Diego Zoo Safari Park,” Darla  Davis, Senior Public Relations Representative for the San Diego Zoo Wildlife Alliance, confirmed today in an  email to ECM.

The International Rhino Foundation estimates there are fewer than 16,000 white rhinos left in the world, due to poaching losses. All but two of these survivors are southern white rhinos; the population has decreased by almost 12% in the past four years.

May 28, 2023 (San Diego’s East County) – The U.S. Department of Agriculture and the U.S. Equestrian Foundation (USEF) will hold a webinar on May 31 at 1 p.m. Pacific Standard Time on Vesicular Stomatis Virus (VSV), a contagious livestock disease that has spread to at least six different communities in San Diego County. Registration is required for the webinar, which will be held on Zoom. Register here.

Dr. Angela Pelzel McCluskey, USDA equine epidemiologist, will provide an overview of Vesicular Stomatitis and the current situation report also providing perspective based on her firsthand experience managing numerous VS outbreaks in her previous roles. Dr. Katie Flynn,USEF Equine Health and Biosecurity veterinarian, will cover prevention measures for horses and their premises, as well as the biosecurity requirements being implemented at those USEF events with horses competing from VS Affected States.

As of Friday, the U.S. Department of Agriculture reports that 23 properties are quarantined due to VSV, including 18 sites in San Diego County—seven more than in the last report five days earlier.  All but one case in the outbreak have occurred in equine species such as horses, but there is one suspected case  in a “backyard beef steer” at a local property with three cattle. The remaining cases are in Riverside County. 

The USDA has not responded to our media inquiry for specific locations impacted in our region, but the Ramona  Sentinel reports that the first six confirmed cases since the outbreak began May 17 were in Ramona, Lakeside, Campo, Jamul, Del Sur, and Descanso, according to local veterinarians. San Diego and Riverside counties are the only places in the nation with current cases.

QUARANTINES IMPOSED AS VSV LIVESTOCK DISEASE SPREADS ACROSS REGION

Disease can affect all hooved livestock and can also spread to humans

By Miriam Raftery

May 22, 2023 (San Diego) – Fifteen properties in San Diego County are under quarantine by the U.S. Department of Agriculture, after six cases of Vesicular Stomatitis Virus (VSV) have been confirmed in San Diego County and testing is underway on another nine suspected local cases, according to the USDA website on the disease. There are also two confirmed cases and two suspected cases in Riverside County, where four properties are quarantined.  These are the only areas in the U.S. with current cases of VSV.

 The first local case in this outbreak occurred May 17 in Ramona, according to the San Diego Union-Tribune. While all of the local cases so far are in horses, the disease can also afflict donkeys, cattle, pigs, sheep, goats, llamas, alpacas or other hooved livestock.

The quarantines will  last at least 14 days after the last known case.  However blisters on mouths and hooves can take up to two months to resolve.The quarantines mean no transporting animals to or from the impacted properties will be allowed until a veterinarian has cleared animals for travel.  Some states and livestock events such as horse shows may prohibit animals from the impacted areas from participating even if there is no known exposure, so check with show organizers before traveling to any livestock even
