Axios reports:

Contact tracing data from around the globe suggests that while there are instances of asymptomatic coronavirus patients transmitting the virus to others, they are not “a main driver” of new infections, World Health Organization officials said at a press conference Monday.

How can this be true, based on all of what we have observed so far? At least Axios adds some context to the statement and concludes: “The bottom line: These statements are a reminder of just how little we understand about this virus.”
