While the risk to people is low with this bird flu outbreak, scientists have rising concerns about the increasing threats of animal-borne viruses spreading to people.
laid off more than 200 employees after an outbreak forced the destruction of 5.3 million laying hens.
After the virus was reported in 41 countries during the latter half of 2021, U.S. and Canadian officials were on high alert, swabbing live birds and ducks taken by hunters to monitor for it, Richards said. Maps of the outbreak this spring showed the flu moving along the Missouri River basin, “very clearly on the wings” on migrating waterfowl, Richards said.
The opportunities for new emerging pathogens to appear and spill over into people has increased in recent decades, researchers said. For example, Richards pointed to the COVID-19 virus, which was found in a host of captive and wild animals, including lions, tigers, gorillas, cats, dogs, deer and mink.
For example, hunters and individuals handling wild birds should wash their hands. People working to decontaminate poultry farms are advised to wear N95 face masks and gloves, and in some cases protective gowns. Davis said these people should also get tested if they experience any flu symptoms. American Poultry Association members who raise birds for enjoyment and show have also worked to protect their flocks from exposure, said David Adkins, secretary/treasurer and a competition judge. Georgia state officials canceled the association’s semi-annual show in February. Similar shows and fair exhibitions have been canceled in at least five states, including Iowa, North Carolina and Pennsylvania.
