The Lower Salt River has been closed to equine activity due to an outbreak of Vesicular Stomatitis Virus (VSV). The Arizona Department of Agriculture announced the closure as a precautionary measure to prevent further spread of the disease. VSV is known for its high infectivity, with symptoms appearing 3-9 days after infection.
The virus typically circulates between livestock and insect vectors in southern Mexico and occasionally reaches the United States. Black flies, sand flies, and biting midges are recognized as vectors for VSV transmission. Once infected, animals can spread the virus through direct contact with nasal secretions and saliva or through contaminated objects like feeders and water buckets.
Isolation of affected animals is recommended until lesions heal. In rare cases, VSV can cause flu-like symptoms in humans, such as fever and muscle aches, with recovery usually occurring within a week. It is advised that those handling infected livestock wear gloves and practice good hygiene.
All suspected cases must be reported immediately to either the Arizona Department of Agriculture or the USDA using their provided contact information.
