British Columbia's Ministry of Health says the first suspected human case of highly pathogenic avian flu contracted in Canada has been detected in B.C. A

A teenager in British Columbia has become the first person in Canada to test positive for the deadly H5N1 bird flu. Health authorities are urgently investigating how the virus spread, but they assure the public that the risk remains low.

British Columbia health officials have yet to identify a likely source of the infection, though none of the teen's contacts have tested positive for the virus so far.
