On September 10, 2015, the National Veterinary Services Laboratories in Ames Iowa confirmed a finding of vesicular stomatitis virus (VSV) infection in three horses from a premises in Scotts Bluff County, Nebraska. This is the first VSV finding in Nebraska this year.
Since the beginning of this summer’s outbreak, 420 VSV-affected premises have been identified and quarantined in eight states (Arizona, Colorado, Nebraska, New Mexico, South Dakota, Texas, Utah, and Wyoming). Currently, according to USDA’s Animal and Plant Health Inspection Service (APHIS), there are 103 affected premises remaining under quarantine in 6 states (Colorado, Nebraska, New Mexico, South Dakota, Utah, and Wyoming).
Last summer, a total of 435 VS-positive premises were confirmed in four U.S. states including Arizona Colorado, Nebraska and Texas.
The virus is spread primarily by insect vectors, and thus tends to disappear during the winter in temperate climates and break out during the summer, particularly in areas where wet conditions encourage insect populations.
