Equine Infectious Anemia (EIA) Health Alert

E-mail Print

An Equine Infectious Anemia (EIA)-affected premises has been identified in the province of British Columbia. Please note that 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), and 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 December 7, 2018, positive EIA results were confirmed by the CFIA’s national reference laboratory for two horses on a premises in Cariboo Sub. B, British Columbia. The horses had been sampled by an accredited veterinarian at the owner’s request as exposure to EIA was suspected. No clinical signs of disease were noted at the time of sampling. A CFIA investigation is underway and as per program policy, a quarantine has been placed on the infected animals and their on-premises contact animals. The quarantine 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 program policy.

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).. (more)

With neither cure nor vaccine in existence, veterinarians and ­researchers must 
supervise the equine infectious anemia virus ­closely to avoid widespread disease
