Vesicular Stomatitis Virus (VSV): What You Need to Know

Reports  have begun circulating about the Vesicular Stomatitis Virus (VSV) that has been spreading through Colorado and Texas this summer. The last confirmed case of of VSV was in 2009. This year, according to the Animal and Plant Health Inspection Services (APHIS), 241 cases have been confirmed. One-hundred and eighty-six of these cases are in Colorado and the other 55 in Texas. Most recently two premises have been quarantined in Bastrop County, Texas. Although most animals will recover within two-three weeks of receiving treatment, it is a good idea to know what to look for and how to prevent this virus from spreading further.

VSV is most likely transmitted by black and sand flies, so adequate insect control is a must. Once the animal has been exposed, a fever will present itself within 24-48 hours. A normal temperature for adult horses is between 99 and 101 degrees F. Along with fever, lesions can be found in the mouth and along the coronary bands. This can lead to lameness, excessive salivation and a lack of appetite.

If you suspect VSV in any of your horses, an experienced equine vet should be called immediately to administer appropriate treatment. The infected animal should also be quarantined from other horses. Cattle and swine should also be kept at a distance since VSV is contagious to these species as well.

Although VSV is not highly contagious to humans, it is recommended to wear gloves while handling sick animals. If infected saliva enters a human’s saliva, eyes, nose or open wound, it is possible to contract the disease. If you are concerned you may have come in contact with infected saliva, contact your health physician right away.

The spread of this virus may affect some show rings and rodeos, so always check with your area to be sure all your scheduled events are still planned. As usual, use caution with water and grooming supplies, and keep your horse protected from flies.

If you have any further questions regarding the Vesicular Stomatits Virus, contact your veterinarian.
