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.

A teen in Canada may be the first person to catch an H5 bird flu virus within the country. Health officials are now working to confirm the diagnosis.

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.
