CALGARY - Test results have confirmed that two health workers at Alberta Children's Hospital have the H1N1 virus.

Alberta Health Services spokesman Don Stewart says three other staff members have tested negative for the flu virus and results are pending for two others.

Stewart adds there's no risk to staff or patients because none of the workers have been in the hospital since they started showing symptoms.

Officials confirmed earlier this week that two young patients at the hospital had the virus, and they say all the cases are related.
