According to CNN, novel coronavirus pneumonia model predicts that the number of new crown pneumonia deaths in the United States will reach 300 thousand by December 1st, August 7th. But if more Americans wear masks, 70000 of them could be saved.
In the early days of the outbreak, health experts stressed that the elderly were the most at risk. However, as the number of confirmed cases in the United States approaches 5 million, the new crown virus is moving to young people. There has been a surge in confirmed cases among children, adolescents and young people.
U.S. experts say masks can reduce virus transmission by more than 40 percent. If all Americans wear masks every time they go out, they can save 70,000 of them.
William Schaffner, professor of preventive medicine and epidemiology at Vanderbilt University in the United States, said on Friday :" If we all wear masks, we can save a lot of lives, and we need national guidance very much now ."
