The new estimate is based on CDC studies of blood samples collected nationwide.
Presumptive Democratic presidential nominee Joe Biden said Thursday that he would use federal power to require Americans to wear face masks in public -- a move that would mark a significant intervention by the federal government and could see considerable pushback from states.
Biden made the comments in an interview with CBS affiliate KDKA, in which he spoke about what he thinks should be done to reopen the country from the coronavirus shutdown. He said that he wants to see greater use of masks.

A number of states require mask-wearing in public when social-distancing is not possible, while a number of others merely recommend Americans in their states wear masks.

But President Trump has not been seen in public wearing a mask, and has dismissed suggestions he should wear one. He has also suggested they could be counterproductive.
“They put their finger on the mask, and they take them off, and then they start touching their eyes and touching their nose and their mouth,” Trump told the Wall Street Journal last week. “And then they don’t know how they caught it?”

Any federal mandate that people wear masks would likely stir significant opposition, considering that state mandates have proved controversial.
A sheriff in southwest Washington state this week told residents to not be "a sheep" over Gov. Jay Inslee’s new statewide order requiring masks -- although he later clarified that he was not “outwardly saying I want you to violate the orders.”
