A Harvard health expert argued on Tuesday that everyone in the United States should wear N95 masks in order to slow the spread of COVID-19.
Joseph G. Allen, the director of the Healthy Buildings program at the university, wrote an op-ed in the Washington Post and said there was “no reason why an essential worker – and really, everyone in the country – dispenses with masks that filter 95%. “
BIDEN DECLINES TOLD TEACHERS IN CHICAGO TO REFUSE IN-PERSON TEACHING TO RETURN TO WORK
His speech came a day after Dr Anthony Fauci, the leading disease specialist in the United States, said in an interview that wearing two sheet masks “probably” offered more protection for the wearer.
“So if you have a physical coating with one layer you put on another, it makes sense that that’s probably more efficient. That’s the reason why you see people doing double masking or doing some version of an N95. “
President Biden said on Tuesday that masks are “the best defense against COVID-19” in the coming months as his administration acquires a sufficient supply of vaccines to clear the majority of Americans.
“The brutal truth is that it’s going to be months before the majority of Americans get vaccinated – months,” Biden said. “In the coming months, masks, not vaccines, are the best defense against COVID-19. Experts say wearing masks by April alone would save 50,000 lives that would otherwise die if we didn’t wear them.
Fauci’s comment has been criticized on social media. Some have asked why the country was not asked to wear double masks earlier in the outbreak, and others asked – with that logic – wouldn’t three masks be more effective than two?

Scientists continue to learn more about the disease that can be transmitted. The Wall Street Journal reported that a year after the start of the pandemic, we know that wearing a mask and good air circulation inside buildings is more effective in preventing transmission than cleaning up. of surface.
Allen wrote that if two people wore N95s, it would result in a “greater than 99% reduction in exposure.”
“Think about it for a minute. We could reduce exposure by 99% to what should be $ 1 a mask. (Prices are higher now due to the inability to produce an adequate supply.) Add better ventilation. and some distance between people, and you have hospital grade protections, ”he wrote.
