OTTAWA (Reuters) -Canada has detected its first presumptive case of H5 bird flu in a person, a teenager in the western province of British Columbia, health officials said on Saturday. The teenager likely caught the virus from a bird or animal and was receiving care at a children's hospital, the province said in a statement.

A Canadian teenager infected with bird flu — that country’s first case involving a locally acquired infection — is in critical condition and experiencing difficulty breathing, health officials said Tuesday.
