Avian Influenza A (H7N9)

An outbreak of human infections with a new avian influenza A (H7N9) virus was first reported in China by the World Health Organization in March, 2013. Cases have been reported mostly in China. In addition, travel-related cases have been reported in Malaysia, Taiwan, Hong Kong and most recently in Canada.

The first case of avian influenza A (H7N9) in a human in North America was confirmed in January 2015. The individual lives in British Columbia and recently returned home from a trip to China. The person in question did not have symptoms while travelling, but became sick upon after returning to Canada.

The individual was not sick enough to be hospitalized, and is currently recovering. Everyone in contact with the individual is being monitored by public health authorities.

The risk of Canadians getting sick with avian influenza A H7N9 remains very low as evidence suggests that it does not transmit easily from person-to-person.

The majority of people in China infected with avian influenza A (H7N9) had previously been exposed to the live birds, mostly chicken. This particular strain of avian influenza A (H7N9) virus has not been detected in birds in Canada.
