Lockdown Delays Cost at Least 36,000 Lives, Data Show
Even small differences in timing would have prevented the worst exponential growth, which by April had subsumed New York City, New Orleans and other major cities, researchers found.

And if the country had begun locking down cities and limiting social contact on March 1, two weeks earlier than most people started staying home, the vast majority of the nation’s deaths — about 83 percent — would have been avoided, the researchers estimated.

Under that scenario, about 54,000 fewer people would have died by early May.
