Vesicular Stomatitis Virus Confirmed in Boulder, Broomfield County – Colorado Hometown Weekly

Confirmed cases of vesicular stomatitis virus (VSV) have spread to Boulder, Broomfield and Larimer County, Colorado Department of Agriculture officials said Friday. The Equine virus was first diagnosed in Weld County in early July.

According to a statement by the Colorado Department of Agriculture, all confirmed cases have so far been in horses and have been found in Adams, Boulder, Broomfield, La Plata, Larimer and the County of Sweden.

VSV is a viral disease that mainly affects horses and cattle and sometimes pigs, sheep, goats, llamas and alpacas.

A horse infected with vesicular stomatitis has great erosion in the lip. [19659005] In Boulder County, there are 11 cases in quarantine, one in Broomfield County and 18 in Larimer County. In total, 50 cases have been confirmed in the state. Two of them have recovered and been released from quarantine.

The first case was reported on July 3 in Weld County by a field veterinarian with the Colorado Department of Agriculture State Veterinary Office. As of July 8, three states have confirmed VSV-positive cases, including Texas and New Mexico.

The statement said that the transfer process is not fully understood, but includes insect vectors such as black flies, sand flies and biting midges. Incubation time ranges from two to eight days and clinical signs include bladder-like damage to the skin, erosions and sloughing of the skin of the muzzle, tongue, ears, teats and coronary bands.

Officials often say excessive salivation is the first sign of disease, along with a reluctance to eat or drink, and lameness and weight loss can follow.

"People may be infected when dealing with affected animals, but this is a rare event," the statement said. "In order to avoid exposure to humans, people should use personal protective measures when handling the animals concerned."

According to the statement, there is no USDA-approved vaccine for VSV.

Officials say that veterinarians and cattle owners should contact the Member State of destination when moving cattle interstate to ensure that all import requirements are met.
