The CDC said Wednesday "astute" U.S. clinicians found the novel coronavirus in a person who did not recently return from a foreign country nor knowingly have contact with anyone infected, as six more countries reported their first cases.
The big picture: COVID-19 has killed more than 2,800 people and infected over 82,000 others. The number of new cases reported outside China exceeded those inside the country for the first time on Tuesday, the WHO said Wednesday. South Korea has the most, with 1,595 infections confirmed by Wednesday night. Europe's biggest outbreak is in Italy, where 453 cases have been confirmed.
