NPR: Actual Coronavirus
Infections Far Higher Than Confirmed Cases, Model Shows
Ever since the coronavirus reached the U.S., officials and citizens alike have
gauged the severity of the spread by tracking one measure in particular: How
many new cases are confirmed through testing each day. However, it has been
clear all along that this number is an understatement because of testing
shortfalls. Now a research team at Columbia University has built a mathematical
model that gives a much more complete — and scary — picture of how much virus
is circulating in our communities. (Aizenman, Carlsen and Talbot, 2/6)
