The current outbreaks of avian influenza (also called “bird flu”) have caused devastation in animal populations, including poultry, wild birds, and some mammals, and harmed farmers’ livelihoods and the food trade. Although largely affecting animals, these outbreaks pose ongoing risks to humans.
People spread Covid-19 to wild white-tailed deer more than 100 times in late 2021 and early 2022. The infection circulated widely in the deer population in the United States, and in at least three instances, researchers suspect the virus was passed between deer where it picked up unique genetic changes and then re-infected humans.
