Though the possibility of wild birds spreading disease to domestic poultry is low thanks to biosecurity efforts, Dan Grear, a disease ecologist with the USGS National Wildlife Health Center, says that there is still a risk to domesticated poultry due to the virus’ genetic makeup.
“Our analyses showed that HPAI viruses can adapt easily to novel species and environments,” Grear said.
The virus can even. . .
