Equine Influenza in Arizona is a monitored disease. This means at the Department of Agriculture we take reports of outbreaks to understand the spread of this disease and pockets throughout the state, yet as an agency do not quarantine the facility. This does not mean that a farm owner or manager cannot impose a self quarantine on the facility so new animals are not infected.
What causes equine influenza?
Equine influenza A2 virus (EIV) causes flu in horses. In the literature you may see the A2 EIV is also called subtype H3N8 (which, to scientists, relates it to the H3 flu viruses in other animals).
How does my horse get the disease?
Horses often get the flu much like humans do from other humans by coming in contact with an infected horse or from nasal secretions from an infected horse. This often happens during times of stress such as at shows or other events where groups horses commingle. These horses then may bring it home to and spread it through the facility. Young horses (ages 1 to 5) with limited natural immunity, unvaccinated horses, and those that come into frequent contact with large numbers of horses have the highest infection risk.
What can I do to protect my horse?
It is recommended that you work with your veterinarian to determine the risk of your horse due to activities and tailor a vaccination program to protect your equine friend.
