SARS-CoV-2 Lurked for Decades Where Others Like It Lurk Still

Future pandemics—and suffering of the kind inflicted by COVID-19—could be avoided if we troubled ourselves to see where dangerous pathogens lie in wait. We could, two unrelated studies suggest, save ourselves untold woe and conserve our fortunes if we were to look into matters geographic, zoologic, and genomic. More specifically, we need to keep our eyes wide open when we venture into the planet’s last wild places. There, we may run into wild animals that are infected with pathogens harboring wild genetic traits—which is to say, genetic traits that evolved naturally, beyond our gaze, and that waited patiently, perhaps decades, for a chance to strike.
