Since its last Situation Report on Oct. 23, 29 previously VSV-infected or suspect premises have been released from quarantine:

In 2019, seven states have been confirmed with a total of 1,138 VSV-infected or suspect premises: Colorado (690), Kansas (1), Nebraska (26), New Mexico (76), Oklahoma (1), Texas (172), Utah (24), and Wyoming (148).
In those states, 1,087 previously infected or suspect premises have been released from quarantine. All quarantined premises have been released in Oklahoma (since Aug. 7), New Mexico (since Sept. 5), and Texas (since Oct. 31). Quarantines for VSV extend for at least 14 days from the onset of lesions in the last affected animal on the premises.
Vesicular stomatitis virus can cause blisters and sores in the mouth and on the tongue, muzzle, teats, or hooves of horses, cattle, swine, sheep, goats, llamas, and a number of other animals. Lesions usually heal in two or three weeks.
Because of the virus’ contagious nature and its resemblance to other diseases such as foot-and-mouth disease, animal health officials urge livestock owners and caretakers to report these symptoms to their veterinarian immediately. Most animals recover with supportive care by a veterinarian.
“Vesicular stomatitis has been conﬁrmed only in the Western Hemisphere,” APHIS said on its website. “It is known to be an endemic disease in the warmer regions of North, Central, and South America, and outbreaks of the disease in other temperate geographic parts of the hemisphere occur sporadically. The Southwestern and Western United States have experienced a number of vesicular stomatitis outbreaks, (and) the most recent and largest VS outbreak occurred in 2015. Outbreaks usually occur during the warmer months, often along waterways.”
Some states and other countries might restrict movement of, or impose additional requirements for, susceptible animals from states having known VS cases. Before moving livestock, contact the state of destination for its requirements.
