CDC does not recommend to general public due to insufficient inventory of N95 masks for medical personnel

US experts recommend that two masks be overlapped each other to prevent the novel coronavirus infection (Corona 19), CNN broadcasts and others reported on the 28th (local time). While there is a growing concern that the mutant virus has stronger transmission power than the existing virus, it is explained that wearing two masks increases the’protection’ and increases the blocking effect. Experts said that’overwriting the mask’ may be an effective countermeasure, especially when the US health authorities do not recommend N95 masks for medical personnel, which are the most effective for virus protection, to the public. The US Centers for Disease Control and Prevention (CDC) does not recommend wearing N95 to the general public, considering the lack of inventory of masks for medical personnel.
Anthony Pouch, director of the National Institute of Allergy and Infectious Diseases (NIAID), the highest authority in responding to Corona 19 in the United States, appeared on NBC broadcast on the 25th and explained, “Adding a mask will enhance the virus blocking effect.” He said, “If you put an extra layer of shield on, it will be more effective (for blocking viruses) from common sense,” he said. “This is why people wear two masks at a time or change masks to be similar to N95.”
On the 15th of last month, Lindsey Ma, professor of civil and environmental engineering at Virginia Tech, and Monica Gandhi, professor of medical school at the University of California, San Francisco (UCSF), recommended overlapping two masks through commentary. They emphasized, “If you put a cotton mask on top of the surgical mask, you will get maximum protection,” he said. “At this time, the surgical mask will act as a filter and the cotton mask will serve as an additional filter while helping to fit tightly.” . Joseph Allen, an associate professor at Harvard University’s Graduate School of Public Health, analyzed that 91% of the droplets could be blocked by wearing a cotton mask over a surgical mask in a British Daily Guardian article on the 12th.
In fact, American politicians have recently used to overwrite more than one mask. President Joe Biden and Vice President Camela Harris have been “overwriting” for weeks. Former Mayor of South Bend, Indiana, who was appointed Biden’s first transportation minister, Pete Booty, also took a selfie with a partner on the day of the presidential inauguration. Republican members Mitt Romney and senators Marco Rubio also wore’double masks’ in the middle of last month.
