In its July 13 Situation Report, the USDA’s Animal and Plant Health Inspection Service (APHIS) confirmed Missouri’s first equine case of vesicular stomatitis virus (VSV) in 2020. Two horses on a Newton County premises have met the case definition for a newly infected state with VSV, Indiana serotype. An additional horse on the same premises has met subsequent case definition.

The three horses are among nine on the premises. Clinical signs, which began July 7 and 8, include ear lesions in two horses and oral lesions in one. No other susceptible species reside on the premises.

Missouri is the seventh state in the U.S. with VSV outbreaks in 2020. Other affected states include Arizona, Kansas, Nebraska, New Mexico, Oklahoma, and Texas
