Equine Infectious Anemia

 
What is equine infectious anemia?
Equine infectious anemia (EIA) is a contagious blood-borne virus that affects horses and other equines.  There is no vaccine or treatment for this disease.
 
What are the signs of infection?
The symptoms displayed by infected animals may include fever, anemia, jaundice, depression, edema, and chronic weight loss.
 
How is EIA transmitted?
Transmission is typically through large biting insects, such as horseflies, but can also be through contact with equipment or surfaces contaminated with blood from an infected animal.
 
What can I do to prevent EIA in my animals?
Annually test your animals, especially when they have been in contact with equines of unknown EIA status, and avoid exposure to animals known or suspected to be infected with EIA.
 
What are the testing requirements for EIA?
There is no testing requirement for animals living in the state of Idaho that travel within state borders.  Most, if not all, states require EIA testing on equine imports.  Animals entering Idaho from another state must have had a negative EIA test within 12 months prior to movement into Idaho.  Some in-state equestrian events/exhibitions may require all animals to provide proof of negative EIA testing, regardless of the state of origin.
 
What will testing cost me?
Contact your veterinarian for their EIA testing rates.
 
What do I do if I have positive animals?
Animal Industries must be notified of positive animals within 24 hours of test results.  The disposition of these animals will be determined at the time of notification.
 
Equine Infectious Anemia is a reportable disease in Idaho.
