HOW DO ANIMALS FIT INTO THE VIRAL PUZZLE?

摘要

Epidemiologists agree that the disease likely thrived in bats before it made the zoonotic leap to humans-plus pangolins, dogs, cats, tigers, lions, and minks. But that's about where the consensus ends. Biologists and virologists need to dissect how different creatures interact with germs like SARS-CoV-2, which causes COVID, to understand how public health crises emerge. Part of that means digging into human-wildlife relationships-and how they change as people take over more of the world. We asked the experts where threats lurk as we push those barriers, and what more we need to learn.
