MANILA (SDN) — Wearing Mask, Washing Hands, Social Distancing!
These are the three minimum health protocols that every person must and ought to comply with.
It’s for the protection of the wearer and others from aerosols or droplets from a sneezing or coughing person.
Wearing the cloth to cover the face — essentially the nose and mouth (face shield for the eyes) has become the new normal in the time of the coronavirus pandemic.
Now comes a new trend, the wearing of two masks. It’s called double masking. Another mask layered over the first one.
Experts, as reported by CNN on January 28, 2021, say double masking increases protection from catching SARS-CoV-2, the virus that causes the coronavirus disease (Covid-19).
Consider that the United Kingdom variant (B117) of the coronavirus first discovered in September 2020 is transmitted easily — from 50 to 70 percent faster — and is now spreading in a number of countries, including the Philippines. Add to that that new Covid-19 variants are being discovered in some parts of the world.
Double masks for American leaders
So, for more protection, by preventing infected persons’ aerosols’ easy entry to the nose, do what United States President Joseph “Joe” Biden and Vice President Kamala Harris have been doing.
The two-newly proclaimed American leaders have been wearing double masks in public.
CNN said public health officials have suggested the layering of masks to increase the level of protection, citing Dr. Anthony Fauci, the American President’s chief medical adviser, in a report Sandee LaMotte authored.
“Common sense,” the health expert pointed out.
“If you have a physical covering with one layer, you put another layer on, it just makes common sense that likely would be more effective, that’s the reason why you see people either double masking or doing a version of N95,” he said.
Sandee LaMotte’s report cited a study last year that said “surgical masks we’re about 50 percent effective at protecting the wearer from other people’s aerosols and between 60 percent and 70 percent effective at protecting others.”
In the same CNN report, it mentioned the advantage of a mask layering.
On the other hand, “removal efficiency for particles” is “over 91 percent.” The words are from Joseph Allen, an associate professor at the Harvard T.H. Chan School of Public Health. He is also director of the school’s Healthy Building program on the increased protection when wearing a surgical mask and topped by a cloth mask.(✓)
