Suara.com – Since the pandemic corona virus Covid-19, usage face mask has become an obligation to prevent transmission. The general public is advised to use cloth mask two layers and surgical masks as well as N95 are used by medical personnel.
But now, health expert Dr Anthony Fauci said a new variant of the corona virus Covid-19 is more contagious than the previous variant. He thinks wearing 2 masks at once might help protect yourself.
This new variant of the corona virus is considered to be easier to bind to our body cells. The more layers that cover the nose and mouth, the less likely a person is to be exposed to corona virus particles that infect body cells.
In this case, wearing two masks at once might help establish a stronger protection between you and the corona virus.
“The more layers of masks you use, the more barriers that can protect you from spreading the virus,” said Thomas Duszynski, director of epidemiology education at the School of Public Health, Richard M. Fairbanks at Indiana University. Huffpost.
In fact, the N95 mask is the best standard to protect us from the corona virus. If you can get an N95 mask and also wear a surgical mask to double it. Then you will be better protected from corona virus particles.
However, Onyema Ogbuagu, a Yale Medicine infectious disease doctor and principal investigator of the Pfizer Yale trial, is unsure if someone is going to double the use of surgical masks and cloth masks.
According to Ogbuagu, wearing two masks at the same time provides stronger filtering capacity and durability. Because, masks can filter the air we breathe and limit the amount of respiratory secretions that come out.
The KN95 mask is considered a fairly good alternative to the N95 mask in warding off viruses. However, the KN95 mask may not be as tight as the N95 mask.

Even so, the KN95 mask still provides strong protection for you and others by sealing the parts around the nose and mouth.
Meanwhile, surgical masks are great for protecting you and others from large respiratory droplets. The drawback is that surgical masks do not easily prevent all the smaller aerosol particles, due to their often looser size.
If you want to double the use of masks, you can use masks with the greatest filtering ability first, such as N05, KN95 or surgical masks.
Make sure that the mask is tightly closed on your face and that there are no gaps where air can contaminate or enter.
A data also suggests that certain cloth masks may no longer be effective in preventing the transmission of new variants of the corona virus. You don’t only need a two-layer cloth mask, but you need multiple layers to make it stronger.
In general, the more layers of cloth used to make masks, the better it is to protect yourself and those around you.
Research has found that a multi-layered mask can block 50 percent to 70 percent of tiny droplets. Regarding cloth masks, evidence shows that three layers of tightly woven fabrics are the right choice.
