Lewiston Roundup closes facilities amid horse virus outbreak

The Lewiston Roundup has closed its equine facilities for 21 days in response to a warning from the Idaho State Department of Agriculture regarding an outbreak of Equine Herpesvirus Type 1 (EHV-1). No confirmed cases exist in Idaho, but officials are urging caution due to the virus's highly contagious nature. This closure impacts planned barrel races and restricts livestock movement on the grounds. Horse owners who attended recent equine events in Texas, Oklahoma, or Louisiana are advised to contact the Idaho State Veterinarian and quarantine their horses for 21 days. The Lewiston Roundup stated that this decision is made to protect the health and safety of all horses on-site.

EHV-1 can lead to severe health issues, including respiratory disease, abortions in pregnant mares, and neurological disorders. The Idaho State Department of Agriculture warns that the virus spreads easily through direct contact and contaminated equipment. Regular temperature checks are recommended for horses at risk of exposure, with immediate isolation for any showing fever.
