How do scientists working with bats deal with the possibility of spillover?

SARS-CoV-2 most likely emerged from bats in China, then jumped to another animal, and then infects humans.But now, people are taking risks Spread the virus back Into the animal population, this phenomenon is called spillover. To avoid this, the U.S. Geological Survey and the U.S. Fish and Wildlife Service recently issued guidelines for biologists working with bats, recommending that they wear protective equipment including masks.
