U.S. coronavirus testing levels off at half of what experts say is needed

The number of coronavirus tests completed daily has plateaued again, after steadily rising for about a week.

Why it matters: This is about half of what some experts say we need to be doing every day to safely return to normal life, with others saying the target is even higher. The more testing we do, the more likely we are to catch outbreaks before they get out of control.
