Dr. Anthony Fauci, director of the National Institute of Allergic Reaction and Infectious Illness, said that when it comes to using two masks to safeguard versus the coronavirus, it “makes common sense” that more than one layer of masking would be more effective.
There is no specific research on how well face coverings work against brand-new variants of the infection, consisting of the more transmissible variant from the UK that has been spotted in at least 22 states in the United States.

A mask “is a physical covering to avoid droplets,” Fauci stated Monday on NBC’s “TODAY” program. “So, if you have a physical covering with one layer, you put another layer on, it simply makes good sense that it likely would be more reliable.”
Asked at a White Home rundown recently whether the new variant would make masks less reliable, he said that on the contrary, the variations are “the reason that you absolutely should be using a mask.”
Dr. Marybeth Sexton, an assistant professor of transmittable diseases at the Emory University School of Medicine in Atlanta, agrees with Fauci’s view.
The new variants “might lead individuals who have them to have a greater amount of virus in their nose, in their mouth, so that when they breathe or talk or cough or sing, they may put more viral particles out in the environment than the average person,” she stated.
But, Sexton added, “that need to not be a big issue if everyone has a mask on.”
If worn correctly, face coverings are anticipated to assist prevent the spread of any breathing virus, no matter the variant.
” If that wasn’t clearly apparent 6 months earlier, it surely is now,” said Cameron Wolfe, a contagious diseases expert and an associate teacher of medicine at the Duke University School of Medicine.
Which mask should you wear?
The secret is to strike a balance in between comfort and efficiency.
” If you put three or four masks on, it’s going to filter much better due to the fact that it’s more layers of fabric,” stated Dr. Scott Segal, chair of anesthesiology at Wake Forest Baptist Health in Winston-Salem, North Carolina. “But you’ll be taking it off due to the fact that it’s unpleasant.”
Segal has been studying face covering fabrics for much of the past year in response to the pandemic. In general, he stated, 3-ply medical-grade surgical masks tend to provide the very best protection for the average individual.
For those opting for cloth masks, Segal recommends “two layers of top quality cotton material with a relatively high thread count.”
Acceptance of face coverings has actually come a long way over the previous year. Americans significantly utilize them as a way to make style statements or to show love for their favorite sports groups.
Appropriately, the mask-making market has taken off with little oversight. There is no standardized tool– such as one that’s comparable to a nutrition facts label on food– for consumers looking to gauge mask quality.
Technically, the Food and Drug Administration regulates masks, including fabric face coverings, however just when they are marketed specifically for “medical functions.” Many business do not explicitly advertise their items as such (in reality, lots of state that their masks are not for medical use), putting the onus on consumers to decide which might provide the most protection.
The gold basic N95 mask is not advised for the average individual, according to the Centers for Disease Control and Avoidance, and instead must be scheduled for healthcare professionals.
” You could have a very good N95 mask, but let’s state that someone isn’t using it properly or is only using it 50 percent of the time,” stated Dr. Leana Wen, an emergency situation doctor and previous health commissioner for Baltimore. “I would rather that somebody wear a surgical mask or fabric mask 100 percent of the time, correctly and consistently.”
In 2015, the FDA authorized the Chinese variation of the N95, called KN95, for emergency use. Nevertheless, fake versions of KN95 s have flooded the market. The National Institute for Occupational Safety and Health, part of the CDC, has an in-depth, visual list of knockoff brands.

One simple way to check fabric masks in your home is to hold it approximately a light. If light shines in between the cloth’s individual fibers, it probably suggests that viral particles can survive, too, Segal said.
His research, which has actually not yet been peer-reviewed or released in a journal, has likewise discovered that adding a piece of flannel in between layers of cotton might also be an effective way to filter viral particles. That can be contributed to masks that include an opening in the middle so users can place an extra filter.
Segal did not suggest using coffee filters or industrial grade vacuum filters, pointing out an absence of evidence they work well to filter viral particles properly. Other filters, such as PM2.5 filters, won’t block viral particles, however can be counted as an additional layer in a mask.
No matter what type of mask is utilized, the most crucial thing is to wear it correctly.
” I fret more about people wearing masks down on their chins, not covering their mouths and noses, than I do about what the mask is made of,” said Dr. Richard Besser, president of the Robert Wood Johnson Structure and a former acting director of the CDC.
Indeed, “the very best quality mask is frankly the one that you use the proper way for the longest amount of time when you’re connecting with other individuals,” Wolfe, of Duke University, said.
Face coverings need to extend from the top of the nose to the chin without spaces on the sides.
” If your nose is sticking out, it’s completely ineffective,” Segal stated.
Other pointers consist of:
- Avoid masks with a valve. Segal said that while the valve enables much easier breathing, it defeats the function of wearing a mask due to the fact that it lets viral particles out, putting others at threat
- Keep additional masks on hand in case one breaks or ends up being soiled
- Hard plastic face guards ought to not utilized be a replacement for fabric or medical-grade masks, according to the CDC.
