Andrew Noymer, an associate professor of public health at the University of California, Irvine, recently told Insider that the US may be underestimating the prevalence of asymptomatic infections.

Given that asymptomatic people are less likely to seek a test, this could indicate that official case counts are missing a lot of infections.
