Equine Infectious Anemia

Equine infectious anaemia (EIA) is an infectious and potentially fatal viral disease affecting the immune system of members of the Equidae family, including horses, donkeys and mules. Most EIA-infected horses show no clinical signs of disease; however, they remain carriers of the virus for life and can be a source of infection for susceptible animals. In Canada, EIA is listed as a reportable disease under the Health of Animals Regulations. Accordingly, when EIA is suspected, it must be reported to the Canadian Food Inspection Agency (CFIA).
