Vesicular stomatitis virus (VSV) has been confirmed in horses in Grant County, NM. A viral disease primarily affecting horses, cattle and swine, VSV causes blister lesions in the mouth and on the dental pad, tongue, lips, nostrils, hooves and teats. The blisters burst, leaving raw tissue so painful infected animals generally refuse to eat and drink and show signs of lameness.

Two of six horses had clinical VSV signs, but none of the 110 cattle showed symptoms. All susceptible animals are being held on the premises. To learn more, visit or call APHIS Emergency Management Staff at 301/734-8073.
