Ask KHN-PolitiFact: Is My Material Masks Good Sufficient? The 2022 Version



By Victoria Knight, Kaiser Well being Information

The extremely transmissible omicron variant is sweeping the U.S., inflicting an enormous spike in covid-19 circumstances and overwhelming many hospital methods. Apart from urging People to get vaccinated and boosted, public well being officers are recommending that individuals improve from their fabric masks to higher-quality medical-grade masks.

However what does this even imply?

At a current Senate Well being, Training, Labor and Pensions Committee listening to, high public well being officers displayed various kinds of masking. Dr. Rochelle Walensky, director of the Facilities for Illness Management and Prevention, wore what seemed to be a surgical masks layered beneath a fabric masks, whereas Dr. Anthony Fauci, chief medical adviser to the president, wore what appeared like a KN95 respirator.

Some native governments and different organizations are providing their very own insurance policies. Los Angeles County, as an illustration, will require as of Jan. 17 that employers present N95 or KN95 masks to workers. In late December, the Mayo Clinic started requiring all guests and sufferers to put on surgical masks as a substitute of fabric variations. The College of Arizona has banned fabric masks and requested everybody on campus to put on higher-quality masks.

Questions in regards to the degree of safety in opposition to covid that masks present — whether or not fabric, surgical or higher-end medical grade — have been a topic of debate and dialogue because the earliest days of the pandemic. We appeared into the query final summer season. And as science adjustments and variants emerge with larger transmissibility, so do opinions.

The Facilities for Illness Management and Prevention has not up to date its masks steerage since October, earlier than the omicron variant emerged. That steerage doesn’t suggest using an N95 respirator however states solely that masks needs to be at the very least two layers, well-fitting and comprise a nostril wire.

A number of specialists we consulted stated that the present CDC steerage doesn’t go far sufficient. Additionally they agreed on one other level: Carrying a fabric masks is best than not sporting a masks in any respect, however if you happen to can improve — or layer fabric with surgical — now could be the time.

Though fabric masks might seem like extra substantial than the paper surgical masks possibility, surgical masks in addition to KN95 and N95 masks are infused with an electrostatic cost that helps filter out particles.

“From the angle of understanding how covid is transmitted, and what we learn about omicron, sporting a higher-quality masks is absolutely essential to stopping the unfold of omicron,” stated Dr. Megan Ranney, tutorial dean for the Faculty of Public Well being at Brown College.

A large-scale real-world research carried out in Bangladesh and revealed in December confirmed that surgical masks are more practical at stopping covid transmission than fabric masks.

So, one simple technique to enhance safety is to layer a surgical masks beneath fabric. Surgical masks might be purchased comparatively cheaply on-line and reused for a couple of week.

Ranney stated she advises individuals who go for layering to place the better-quality masks, such because the surgical masks, closest to your face, and put the lesser-quality masks on the skin.

In case you’re actually pressed for sources, Dr. Stephen Luby, a professor specializing in infectious illnesses at Stanford College and one of many authors of the Bangladesh masks research, stated surgical masks might be washed and reused, if funds are a problem. Almost two years into the pandemic, such masks are low cost and plentiful within the U.S. and plenty of retailers make them accessible freed from cost to clients as they enter companies.

“Through the research, we informed the contributors they might wash the surgical masks with laundry detergent and water and reuse them,” Luby stated. “You lose some impact of the electrostatic cost, however they nonetheless outperformed fabric masks.”

Nonetheless, specialists keep that sporting both a KN95 or an N95 respirator is the perfect safety in opposition to omicron, since these masks are extremely efficient at filtering out viral particles. The “95” within the names refers back to the masks’ 95% filtration efficacy in opposition to certain-sized particles. N95 masks are regulated by the Nationwide Institute for Occupational Security and Well being, whereas KN95s are regulated by the Chinese language authorities and KF94s by the South Korean authorities.

People have been initially urged to not purchase both surgical or N95 masks early within the pandemic to make sure there can be a adequate provide for well being care staff. However now there are sufficient to go round.

So, in case you have the sources to improve to an N95, a KN95 or a KF94 masks, you need to completely achieve this, stated Dr. Leana Wen, a professor of well being coverage and administration at George Washington College. Though these fashions are costlier and might be extra uncomfortable, they’re definitely worth the funding for the security they supply, she stated.

“[Omicron is] a way more contagious virus, so there’s a a lot decrease margin of error regarding the actions you have been as soon as capable of do with out getting contaminated,” Wen stated. “We now have to extend our safety in each means, as a result of every little thing is riskier now.”

Wen additionally stated that although these masks are characterised as one-use, until you’re in a well being care setting, KN95s and N95s might be worn greater than as soon as. She makes use of one in all her private KN95s for greater than per week at a time.

One other necessary factor to notice is there are numerous counterfeit N95 and KN95 masks being offered on-line, so shoppers should be cautious when ordering them and you should definitely get them solely from a authentic, trusted vendor.

The CDC maintains a listing of NIOSH-approved N95 respirators. Wirecutter and The Strategist have each revealed guides to buying authorized KN95 and KF94 masks. Ranney additionally recommends consulting the web site Undertaking N95 or engineer Aaron Collins’ “Masks Nerd” YouTube channel.

And keep in mind, the chance of transmission relies upon not simply on the masks you put on but in addition the masking practices of others within the room — so going into a gathering or restaurant the place others are unmasked or sporting solely fabric masks will increase the chances of getting contaminated, regardless of how cautious you’re. This chart demonstrates the large variations.

Even with a masks improve, if you’re nonetheless frightened about omicron and, specifically, a severe case of covid, the No. 1 factor you are able to do to guard your self is get vaccinated and boosted, stated Dr. Neal Chaisson, an assistant professor of medication on the Cleveland Clinic.

“There’s been a number of discuss individuals who have been vaccinated getting omicron,” stated Chaisson. “However I’ve been working within the ICU and possibly 95% of the sufferers that we’re taking good care of proper now didn’t take the recommendation to get vaccinated.”
