CIDRAP As a Canadian teen remains in critical care with an H5N1 avian flu infection in a British Columbia hospital, health investigators said today they haven’t identified the source, but have found other clues such as virus changes that may have led to a more severe lower respiratory infection.
At a briefing today, Bonnie Henry, MD, MPH, British Columbia’s health officer, said an exhaustive search has found no related illnesses. For now, the main part of the investigation is at a standstill while scientists do ongoing work to examine virus mutations and conduct serology tests to see if any asymptomatic illnesses have occurred.
