Vesicular Stomatitis Alert

Vesicular Stomatitis Alert 4/27/2020

Vesicular Stomatitis Virus (VSV) causes blister-like lesions in the mouth and on the lips, nostrils, hooves, and teats of horses, cattle, swine, and occasionally sheep and goats. VSV causes weight loss, lameness, and in dairy cows, decreased milk production. VSV has recently been confirmed in Arizona, New Mexico, and Texas:

  • New Mexico index case April 13
  • Arizona index case April 22
  • Texas index case April 23

The outbreaks of VSV may impact imports into the State of Alaska. Canada is not allowing importation or transit of any VSV-susceptible species from the affected states (AZ, NM or TX). Accredited Veterinarians issuing animal movement papers need to verify that animals have not been in one of those 3 states within the past 21 days.

For more information on VSV, and an overview of active and historical outbreaks, visit the USDA APHIS VSV website.
