Dr. Anthony Fauci says two masks are better than one.
“It just makes sense that it would probably be more effective,” Fauci, director of the National Institute of Allergy and Infectious Diseases, told NBC Today Show this week. “That’s why you see people either double-masked or making a version of an N95.”
The US Centers for Disease Control and Prevention has not issued official guidelines on double masking. He did not support wearing face coverings until April 3 last year to help prevent the carrier from spreading the coronavirus, but since then health professionals say it also helps prevent carrier infection.
“A mask is like an obstacle course for particles,” Linsey Marr, a virus transmission expert and professor of civil and environmental engineering at Virginia Tech, told AARP. A second mask “increases the chance that the particle will be trapped before it passes.”
On Tuesday, 99.9 million people worldwide contracted COVID-19 and more than 2.1 million people died. The United States recorded 25.3 million cases and 421,890 deaths, according to data from Johns Hopkins University.
Fauci recently said more people are expected to receive vaccines by April to help prevent the spread of COVID-19. “I would expect it to arrive in April, it will be what we call an open season for vaccines,” Fauci told NPR. “Everyone will be able to get a vaccine. So, I think that by the end of the summer, if we vaccinate between 70% and 85% of the population and we get a good immunity of the herd, I think that by autumn we could start to approach a form of normality ”.

US President Joe Biden last week signed a masked warrant for all federal workers and anyone in federal ownership. According to the mandate, “everyone should wear masks, maintain physical distance and adhere to other public health measures, as required by the CDC guidelines.”
Fauci told NPR: “We want to reach 1 million vaccinations a day. The idea of having everyone wear a mask for at least 100 days – at least. Everyone uniformly, so we have no disparities where some people adhere to public health measures and others do not. ”
