For a disease that didn’t even have a name until February 12—that’s when health officials dubbed it COVID-19—it seems to have become a global problem almost overnight.

In all, about 97 countries have seen instances of the coronavirus, the New York Times reports. And those are probably conservative estimates given that many people with mild symptoms may not seek testing or treatment.
