Information About COVID-19 Non-Medical Face Masks

The selection and use of face masks with regard to protection from Coronavirus, a.k.a, COVID-19, confuses many people. That is understandable, since the experts, most notably, Dr. Fauci, have radically shifted the position and statements about the use of facemasks. At first he said we should not purchase an N95 respirator, as they would not be effective, and now he says we should just cover our faces with any old piece of cloth... and should do that for the rest of time.

We'll try to straighten out facts from government policy and social convention below!

Surgical mask, also called a face mask

A logical starting place is to understand what the goal of wearing a facemask is.

  1. To prevent the wearer from inhaling airborne pathogens, dusts, gases and other harmful particles or droplets.
  2. To prevent the wearers own droplets, mucus, sneezes, coughs etc. from projecting outwards, and thus to minimize the threat or spread of these droplets.
    people who have symptoms of a communicable illness should stay home. But what about those who have no symptoms, but could be contagious?
    That's the purpose of social distancing (staying at least 6 feet away from other people) and wearing cloth face coverings in public settings. Cloth face coverings provide an extra layer to help prevent the respiratory droplets from traveling in the air and onto other people.

That's it... there's really no other medical purpose than these two.

Effectiveness of face mask wearing

According to the AAMC:

Mounting scientific research shows that widespread wearing of masks, along with practicing social distancing and frequent hand-washing, would greatly reduce community transmission of the virus. The effectiveness of masking was recently highlighted by a study that found two COVID-19-positive Missouri hair stylists did not pass the virus on to any of their 139 clients. The stylists and their clients wore masks.

It is noteworthy that they cite the effectiveness of "widespread" wearing of face coverings only in conjunction with "social distancing and frequent hand-washing". In other words, by themselves, the face masks are not very effective at stopping the spread of COVID for the person wearing a mask..

The Mayo Clinic makes a similar statement:

Yes, face masks combined with other preventive measures, such as frequent hand-washing and social distancing, help slow the spread of the virus.

Theses statements and those made by other medical authorities are general statements about the value of wearing face coverings to a society in slowing the spread of COVID. Unfortunately, none of them present any hard data. Nor have we found a single scientific study of a rigorous nature that examined large numbers of individuals wearing face coverings, compared with those who didn't. As near as we can tell, their conclusions about face mask wearing are largely, if not entirely, conjecture. The studies the AAMC cites above are just 2 case studies, not a reproducible scientific experiment nor a study of a large scale population. .

Social value of facemasks

There is another reason for wearing a wearing a nonmedical or homemade mask ; giving some confidence to others that they are at less risk from you, if you are asymptomatic.

Where and when should you wear a facemask or face covering

Many state and federal government agencies offer the following standard guidance:

Wear a face covering when:

  • Shopping at essential businesses, like grocery stores or pharmacies;
  • While visiting your health care provider;
  • Traveling on public transportation;
  • Interacting with customers/clients at essential businesses;
  • When feeling sick, coughing, or sneezing;

The governments are popularizing the phrase: "my mask protects you, your mask protects me."

Many large companies: Costco, Sam's Club, Walmart, Target, Kroger, etc are all requiring customers to wear face masks.

Types of Facemasks

So any face covering (with the possible exception of a crocheted homemade face mask) will help to minimize the outward projection of a wearer's respiratory droplets from coughs, sneezes and speaking.

But obviously some masks are more effective than others at protecting the user from inward inhalation of droplets and pathogens.

For the goal of protecting the wearer from inhaling pathogens, the mask must be a medical-grade mask and properly fitted and worn correctly.

Who should NOT wear a facemask?

The CDC recommends that these groups should not wear a facemask or face covering:

  • Children under age 2
  • Anyone who has trouble breathing, or is unconscious, incapacitated or otherwise unable to remove the mask without assistance
