Fact check: Masks can keep out COVID-19 particles even though smaller than dry wall dust – USA TODAY

The claim: If masks can not keep out drywall particles, they can not keep out coronavirus, which is smaller sized
As the pandemic has continued, social media posts have actually questioned the effectiveness of some masks to stop coronavirus since of their inability to stop the transmission of larger particles.
” The typical size of drywall dust particles is 3 microns,” a Facebook post on July 7 states. “The average size of a coronavirus particle is.3 microns. If masks cant prevent drywall dust getting through, how can they perhaps prevent something 10x smaller from getting through?”
The post consists of two pictures of a person with an ear-loop surgical mask resting beneath his chin and lines of white dust on the sides of his nose and around his eyes, above where a properly worn mask would sit. To date, one post has more than 20,000 shares and over 1,300 comments, and lots of other variations appear on Facebook.
U.S.A. TODAY has actually reached out to the user who posted the viral meme for comment.
Reality check: Whats real and whats false about face masks?
What are the mask suggestions?
With more than 5 million cases and 162,000 deaths from COVID-19 in the United States, according to Johns Hopkins University information, contagious disease experts still advise using a mask in public and physical distancing.
The Centers for Disease Control and Prevention began recommending the use of masks in April.
” Wear cloth face coverings in public settings where other social distancing measures are hard to keep, such as grocery stores, pharmacies, and gas stations. Cloth face coverings may slow the spread of the virus and help individuals who may have the infection and do not understand it from transferring it to others,” guidance from the CDC states.
More than 30 states have actually instituted a statewide order requiring masks in public places. In states without a mandate, regional governments have actually stepped and instituted their own orders to slow the spread even at the threat of dealing with litigation.

In Florida, where the variety of cases continues to balloon, more counties and cities are releasing local mandates as Gov. Ron DeSantis has withstood providing a statewide order, despite Florida ending up being the 2nd state to surpass half a million cases.
” I would have liked to see mask orders previously. Regrettably, there have actually been a lot of blended messages from lots of places about transmission and whether masks work,” Cindy Prins, Master of Public Health Program Director at the University of Florida, told Fort Myers News-Press.
Just California has experienced more cases in the U.S than Florida.
While there are considerable differences in the purification abilities of cloth, surgical and N95 masks, all aid in avoiding the transmission of coronavirus droplets to some degree, scientists say.

On COVID-19 particle size
Dr. Amy Price, a research scientist at Stanford University who was involved in changes to World Health Organization mask guidelines, told Stanford Medicine that masks could affect how far viral particles can take a trip. The beads that carry the viral particles are likewise bigger in size than the infection itself, she kept in mind.
” Many people argue that fabric masks cant be effective because they cant filter out viral particles, which are exceptionally small,” she stated. Trapping droplets with the mask implies not nearly as numerous viral particles escape.
The COVID-19 particle is undoubtedly around 0.1 microns in size, but it is constantly bonded to something bigger.
” There is never ever a naked virus floating in the air or launched by people,” stated Linsey Marr, a teacher of civil and ecological engineering at Virginia Tech who specializes in airborne transmission of infections.
” Breathing and talking generate particles around 1 micron in size, which will be collected by N95 respirator filters with really high effectiveness,” stated Lisa Brosseau, a retired professor of occupational and ecological health sciences who invested her career investigating breathing defense.
Surgical and fabric masks do not secure the user from COVID-19 particles as well as medical N95s. (The type of N95 masks used in construction are ineffective against the novel coronavirus because they have valves.).
However the CDC does note, ” A fabric face covering may not protect the user, but it may keep the wearer from spreading out the infection to others.” By wearing a fabric covering in public, the spread of the virus can be slowed by lessening the transmission to others.
Reality check: Masks are effective versus COVID-19; OSHA doesnt state they use no protection.
Proof shows masks assist slow the spread of COVID-19.
A research study released in June in the Proceedings of the National Academy of Sciences by scientists from Texas A&M University, University of Texas, California Institute of Technology and University of California, San Diego found that masks contributed in decreasing the number of infections in locations like Italy and New York.
” We conclude that using of face masks in public corresponds to the most reliable means to prevent interhuman transmission, and this affordable practice, in conjunction with comprehensive screening, quarantine, and contact tracking, positions the most probable combating chance to stop the COVID-19 pandemic, prior to the development of a vaccine,” the scientists wrote.
A research study by University of Iowa scientists released in Health Affairs Journal in June found similar results.
” The research study provides evidence that US states mandating using face masks in public had a greater decrease in daily COVID-19 development rates after releasing these mandates compared to states that did not release mandates,” scientists composed.

Procedures of the National Academy of Sciences, June 11, ” Identifying air-borne transmission as the dominant path for the spread of COVID-19.”.
The News-Press, July 17, “Lee, Collier amongst 12 COVID red zones needing mask requireds, dripped White House report says.”.
Centers for Disease Control and Prevention, Aug. 7, ” Considerations for Wearing Masks: Recent Studies.”.

That study notes there is contention surrounding the advised use of masks and yields that a massive research study has actually not been done, but cites asymptomatic cases as a strong factor to motivate face coverings.
” Because mask wearing by contaminated individuals can minimize transmission threat, and since of the high percentage of asymptomatic contaminated individuals and transmissions, there seems a strong case for the effectiveness of widespread use of face masks in minimizing the spread of COVID-19. Nevertheless, there is no direct evidence thus far on the magnitude of such impacts, particularly at a population level.”.
Truth check: Ear loop masks, homemade fabric masks, provide protection versus COVID-19.
Our ruling: False.
While not all masks are 100% reliable in stopping transmission of coronavirus droplets, studies reveal masks have actually been beneficial in slowing the spread of disease and have had a greater result when comparing locations with and without requireds. The typical COVID-19 particle might be smaller than drywall dust however is transferred in beads that are larger, allowing them to be caught by face coverings. Because it is not supported by our research, we rate this claim as FALSE.

If masks cant prevent drywall dust getting through, how can they potentially prevent something 10x smaller from getting through?”
” Many people argue that cloth masks cant be effective since they cant filter out viral particles, which are very tiny,” she stated. Catching beads with the mask suggests not almost as lots of viral particles escape. When all parties in an event are using sound, well-fitting masks, it supplies an extra layer of security for everyone.”
While not all masks are 100% reliable in stopping transmission of coronavirus droplets, research studies show masks have actually been beneficial in slowing the spread of disease and have had a greater impact when comparing locations with and without mandates.
