Virus affecting cattle, horses reported in Weld more than any other US county
Humans in direct contact with infected animals could contract virus
A virus that causes blister-like sores on the mouths or feet of infected animals has been confirmed on eight premises in Weld County since June — more than any other county in the U.S.
The virus, vesicular stomatitis, can infect horses, donkeys, mules, cattle, swine and even humans who come in direct contact with infected animals. The virus is usually most severe to horses, according to the Center for Food Security and Public Health.
Since June, the virus has been confirmed in 13 counties, including Weld and Larimer. Three premises in Weld have been marked as suspect for the virus, according to a report from the U.S. Department of Agriculture.
The blisters caused by the virus swell and break, leaving infected animals with raw tissue that can make it too painful to eat or drink. Blisters around the hooves can also present mobility issues. A severe drop in milk production is often seen among dairy cows.
Insects, particularly sand flies and black flies, can transmit the virus to animals. Once infected, animals can spread the virus through direct contact and contaminated objects. People can get the virus through direct contact with infected animals.
Human symptoms are flu-like, including fever, muscle aches, headache and weakness. In rare cases, humans can get oral blisters similar to cold sores.
Those who suspect their animals may be infected should contact a veterinarian immediately. Humans who may be infected should contact their physicians and tell them they have been in contact with animals infected with the virus.
