New projections from Columbia University Mailman School of Public Health scientists find that delays in reimplementing social distancing following a relaxation of control measures could result in a stronger rebound of COVID-19 infections and deaths.

In a retrospective counterfactual analysis, they find that if social distancing and other control measures had been in place in major U.S. metropolitan areas one to two weeks earlier, more than half of the infections and deaths seen to date could have been prevented.
