Checking for the virus in the feces and saliva of waterfowl that have migrated to Alaska would be the best way to determine if they are carrying the virus and potentially spreading it to North America. This study would provide direct evidence of the mechanism of spread. Testing fecal samples in Asian birds or recording incidence of H5N1 in domestic poultry farms would not necessarily provide information about how the virus made its way to North America. Locating and destroying infected birds in markets may be a preventative measure, but would not shed light on the means of spread.
