The wildfowl were tested as part of the University of Alaska Program for the Biology and Epidemiology of Avian Influenza in Alaska in the last summer (Aug.-Sept 2005). Each bird's cloaca (end of the intestinal tract) was swabbed and then screened for the presence of avian influenza viruses, including the H5N1 subtype which is currently causing human infection in Southeast Asia.
