Models that factor in strong contact reduction suggest deaths will continue to occur, but will “slow substantially over the next four weeks,” the CDC says. “Conversely, models that do not incorporate as strong contact reductions … suggest that total deaths may continue to rise quickly.”

One model cited by the White House coronavirus task force has upped its predicted death toll, projecting 74,000 people in the country will lose their lives to the virus by August. That is almost 7,000 more deaths than a model last week.

The projection was adjusted because of longer peaks in some states and signs that people are b
