Orange over at the Coming Bird Flu Pandemic? (see sidebar) points this out July 6 Flu Update
ProMed has an excellent study of which wild birds are most susceptible to H5N1.
Based on our results, mute swans, cackling geese, and bar-headed geese were identified as waterfowl species that pose the greatest susceptibility to lethal infection and some species shed virus for up to 4 days before becoming ill. Such findings suggest some waterfowl species could spread H5N1 HPAI virus between limited geographic regions, but results do not suggest that these species would be long-term reservoirs for this virus.
