The U.S. Is on the Verge of Lockdown 2.0

The key to restarting the recovery, therefore, is to suppress the virus. For cities and states where the epidemic has subsided, the best tools for preventing new outbreaks are universal mask usage, plentiful testing, prompt contact tracing and isolation of the infected.

And for states such as Texas, Florida and Arizona that have been overwhelmed with new infections, this approach -- although still useful -- won’t be enough.
