Missouri Overtakes Kansas in VSV Activity

Two more counties in southwest Missouri have their first confirmed case of vesicular stomatitis, a virus that causes discomfort and eating difficulties for horses and other hooven animals. USDA’s Animal and Plant Health Inspection Service indicates that 16 locations in eight counties have confirmed or suspected cases of VSV. That includes the first confirmed positive cases in Camden and Douglas counties, each at horse premises. One additional confirmed positive was reported in McDonald County. 14 locations were released from quarantine as of last weekend, including the only active case in Saint Clair County. Eight counties in the state have active, confirmed cases, while the Missouri Department of Agriculture is investigating suspected cases in Howell, Polk and Wright counties.

Kansas, where the first case of the current outbreak occurred two months ago, has seen its number of active quarantines decline to 15 locations. Seven premises in eastern Oklahoma and four in Northwest Arkansas also remain in quarantine.

Vesicular stomatitis causes blister-like lesions to appear in and around the mouth, nose, and coronary band. Crusting scabs can also appear on a horse’s muzzle, lips and ears. Excessive salivation, fever, and a reluctance to eat are also symptoms. Anyone suspecting VSV in their populations should separate affected animals and call their veterinarian.
