How is equine influenza spread?
Equine influenza is spread primarily through direct contact with infected animals or through the air. Horses that cough or sneeze produce respiratory droplets that contain the virus, which can then be inhaled by other susceptible animals. The virus can also survive on surfaces such as door knobs, fences, and equipment for several hours. Therefore, indirect transmission is also possible through contact with contaminated objects.
What are the clinical signs of equine influenza?
The incubation period for equine influenza is typically 1 to 3 days. Common clinical signs of equine influenza include:
* Cough
