Cases of Equine Infectious Anemia in Alberta
As of December 6th, 2021, 87 cases of EIA have been detected on 15 premises, located in 10 different counties or municipalities (Athabasca, Big Lakes, Bonnyville, Foothills, Grande Prairie, Lac Ste. Anne, Opportunity, Parkland, Smoky Lake, and Sturgeon). The Office of the Chief Provincial Veterinarian is electing to notify all owners of horses registered in Alberta’s PID system by email to increase horse owner awareness.
For more current information, new cases are generally available on the Canadian Animal Health Surveillance Systems (CAHSS) equine disease dashboard within 2 to 3 weeks of detection by CFIA. A link to the dashboard can be found at the CAHSS equine network page at https://cahss.ca/cahss-networks/equine

EIA, also known as “swamp fever,” is a viral disease of horses and other equids (i.e. donkeys, mules, and zebras) that causes recurrent episodes of fever, lethargy and destruction of red blood cells (anemia) and platelets (thrombocytopenia).
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.
With neither cure nor vaccine in existence, veterinarians and researchers must supervise the equine infectious anemia virus closely to avoid widespread disease
