B.C. investigating 1st presumptive human case of H5N1 avian flu caught in Canada

British Columbia health officials are investigating what's believed to be the first human case of H5N1 avian influenza caught in Canada after a teenager tested presumptively positive for the disease, the province's Health Ministry announced Saturday. Correction: A previous version of this caption said this was the first human case of avian influenza caught in Canada. In fact, the case is the first domestically acquired case of H5N1 avian influenza in this country. Two poultry farm workers in B.C.'s Fraser Valley fell ill with H7N3 avian influenza during an outbreak in 2004.
