Ask KHN-PolitiFact: Is My Fabric 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 instances and overwhelming many hospital techniques. Moreover 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 latest Senate Well being, Training, Labor and Pensions Committee listening to, high public well being officers displayed several types of masking. Dr. Rochelle Walensky, director of the Facilities for Illness Management and Prevention, wore what gave the impression to be a surgical masks layered below a fabric masks, whereas Dr. Anthony Fauci, chief medical adviser to the president, wore what seemed like a KN95 respirator.

Some native governments and different organizations are providing their very own insurance policies. Los Angeles County, for example, 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 towards covid that masks present — whether or not fabric, surgical or higher-end medical grade — have been a topic of debate and dialogue for the reason that earliest days of the pandemic. We seemed into the query final summer time. And as science adjustments and variants emerge with greater transmissibility, so do opinions.

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

A number of consultants we consulted stated that the present CDC steering doesn’t go far sufficient. In addition they agreed on one other level: Sporting a fabric masks is healthier than not carrying a masks in any respect, however if you happen to can improve — or layer fabric with surgical — now’s the time.

Though fabric masks could 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 attitude of figuring out how covid is transmitted, and what we find out about omicron, carrying a higher-quality masks is de facto vital to stopping the unfold of omicron,” stated Dr. Megan Ranney, tutorial dean for the College of Public Well being at Brown College.

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

So, one straightforward technique to enhance safety is to layer a surgical masks beneath fabric. Surgical masks may be purchased comparatively cheaply on-line and reused for a few 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 surface.

In the event you’re actually pressed for sources, Dr. Stephen Luby, a professor specializing in infectious ailments at Stanford College and one of many authors of the Bangladesh masks examine, stated surgical masks may be washed and reused, if funds are a problem. Practically 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 prospects as they enter companies.

“In the course of the examine, 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, consultants keep that carrying both a KN95 or an N95 respirator is the perfect safety towards 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 towards 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 had been initially urged to not purchase both surgical or N95 masks early within the pandemic to make sure there could be a ample provide for well being care staff. However now there are sufficient to go round.

So, if in case you have the sources to improve to an N95, a KN95 or a KF94 masks, you must completely achieve this, stated Dr. Leana Wen, a professor of well being coverage and administration at George Washington College. Though these fashions are dearer and may be extra uncomfortable, they’re well 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 had been as soon as capable of do with out getting contaminated,” Wen stated. “We’ve to extend our safety in each method, as a result of the whole lot 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 may be worn greater than as soon as. She makes use of one among her private KN95s for greater than per week at a time.

One other necessary factor to notice is there are a lot of counterfeit N95 and KN95 masks being offered on-line, so customers should be cautious when ordering them and make sure you get them solely from a reputable, trusted vendor.

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

And bear 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 carrying solely fabric masks will increase the chances of getting contaminated, regardless of how cautious you’re. This chart demonstrates the massive variations.

Even with a masks improve, in case you are nonetheless frightened about omicron and, particularly, 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 drugs 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 doubtless 95% of the sufferers that we’re taking good care of proper now didn’t take the recommendation to get vaccinated.”
