April 5, 2006 In the next few weeks, millions of songbirds, shorebirds and waterfowl will begin arriving in Alaska to breed. These migratory birds — some of which wintered in Southeast Asia — could bring with them the deadly strain of bird flu known as avian influenza A, or H5N1.
April 2, 2006 It's only a matter of time before the H5N1 bird flu virus reaches the United States, say health officials. Alaska's northwest coast is considered a primary point of entry, and the town of Brevig Mission, which relies on wild birds for subsistence, is worried.
March 30, 2006 An experimental bird flu vaccine has potential to offer protection from a pandemic, according to a study in Thursday's New England Journal of Medicine.

March 24, 2006 New studies show that the avian flu virus doesn't pass easily between humans. Two different teams of scientists think they know why. Their studies appeared this week in Nature and Science and detail what makes this disease different from human flu viruses.
March 22, 2006 Asian bird flu has infected as many as eight people in adjacent villages near the Caspian Sea in Azerbaijan.
February 20, 2006 The great flu pandemic of 1918 killed 50 million people — more than any other disease outbreak in the history of the world.
