The U.S. could have prevented roughly 36,000 deaths from COVID-19 if broad social distancing measures had been put in place just one week earlier in March, according to an analysis from Columbia University.

Underlining the importance of aggressively responding to the coronavirus, the study found the U.S. could have avoided at least 700,000 fewer infections if actions that began on March 15 had actually started on March 8.
