What Equine and Cattle Owners Need to Know:

VSV is a viral disease that primarily affects horses and cattle.
In the past decade, the Southwestern and Western United States have experienced a number of VSV outbreaks. Outbreaks usually occur during the warmer months, often along waterways.
VSV normally has an incubation period of 2-8 days before the infected animal develops blisters that swell and burst, leaving painful sores. The virus can be transmitted through direct contact with infected animals or by blood-feeding insects.
If VSV is confirmed, infected animals are quarantined for 14 days after clinical signs of lesions are observed. This short-term quarantine helps prevent the movement of animals and the spread of the disease to other premises, fairs or markets.

What Veterinarians Need to Know:

If you suspect your client’s animal has VSV, contact your TAHC Region Office for paperwork, procedures, and important sample submission information.
Several states are imposing enhanced entry requirements on Texas livestock due to the VSV cases. For information, contact the state of destination.

Strategies for Preventing VSV
Even with the best defensive measures, VSV could infect a herd. However, these tips may help protect livestock:

Control biting flies
Keep equine animals stalled or under a roof at night to reduce exposure to flies
Keep stalls clean
Feed and water stock from their individual buckets
Don’t visit a ranch that’s under quarantine for VSV. Wait until the animals have healed
