An equine infectious anemia (EIA) affected premises has been identified in the Yukon territory.
Please note the following information is in addition to what the Canadian Food Inspection Agency (CFIA) already communicates to stakeholders which includes:
notification to the relevant provincial veterinary service of any newly affected premises
monthly federally reportable disease updates on the CFIA website (10th of each month), which includes the number of affected premises as well as individual animal cases
communications with the owners or persons directly involved in the case, as outlined in the current EIA program policy
On Feb. 19, 2020, a positive EIA result was confirmed by the CFIA’s national reference laboratory for a horse located on a premises in the rural municipality of Whitehorse in Yukon. The horse had been sampled by an accredited veterinarian at the owners’ request after they had taken ownership of it. No clinical signs of disease were noted at the time of sampling.
A CFIA investigation is underway and as per program policy, movement controls have been placed on the infected horse and its on-premises contact animals. Initial reports indicate there are other equines on the affected premises. Movement controls will remain until all disease response activities have been completed, including follow-up testing and ordering the destruction of positive cases. Trace-out activities may require the CFIA to undertake actions at additional premises as outlined in the current policy.
Please refer to the CFIA EIA website for more information about EIA and the national disease control program. Additional information about the case, including its specific location, cannot be released in accordance with Canadian privacy laws.

What is EIA?
Equine infectious anemia (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).
With neither cure nor vaccine in existence, veterinarians and researchers must supervise the equine infectious anemia virus closely to avoid widespread disease
