Full Guide to Wearing Face Masks

April 24, 2020 business

The New York Times and Washington Post have now come around to a position I advocated for right here on Medium final week: We should always all be wearing masks. Not just health care workers, but ALL of us. Each time we exit in public.


Because they work.

Analysis from the SARS outbreak in 2003 shows that washing fingers 10+ instances daily was 55% efficient in stopping virus transmission; wearing a mask was truly more efficient, reducing transmission by about 68%.

Combining a number of forms of protection — hand washing, masks wearing, gloves, and one other layer of outerwear (gowning) — was 91% effective.

Read that once more: ninety one% efficient at stopping virus transmission.

COVID-19 and SARS are similar types of viruses (coronaviruses), and it is smart that what works to stop transmission for one will work to cease transmission of the other.

Masks work, first, because they’re a physical barrier to whatever’s riding along on that air you’re breathing or moving through. Here’s a chart showing the relative barrier effectiveness for various materials:

Secondly, they work because they preserve you from touching your face all day long. The mask makes you more self-aware of the truth that you’re not supposed to the touch your face- specifically, your mouth, nostril, and eyes, and the areas around them- and when you accidentally do, you’ll contact the masks, not your skin directly.

Third, the expertise of different international locations who masks show that masks work within the real world. Within the words of Jeremy Howard, researcher and Masks4All activist, explaining a chart in his recent Youtube video showing how some nations have successfully “flattened the curve” on new infections: “In the event you look at all of the nations which have flat curves, they are countries where masks-wearing is extremely regular, and NOT wearing a masks in places like public transport would be considered anti-social.” He notes that the Czech Republic went from zero masks utilization to one hundred% in 10 days, and in the process they halted the expansion of new covid-19 cases. The Czechs made their own masks- the government didn’t give them out.

In the event you nonetheless must be persuaded, check out this Chinese research of a neighborhood outbreak case on January 22 during the peak Lunar New Year journey season. A sick particular person on the bus who didn’t interact with anyone spread the virus to 7 others, some of whom have been seated a lot more than 6 ft away. Two new passengers caught the virus half-hour after the original sick person had left the bus. NONE OF THE PEOPLE WEARING MASKS WERE INFECTED. Read the article, it’s very detailed, with a schematic of exactly where people have been sitting on the bus.

So let’s say you’re satisfied, and now you’re thinking of some type of face covering. What are your options?

First, please don’t buy masks commercially, if by some miracle you might find them now. Commercially made PPE must be reserved for medical personnel at this time. Sadly, the scarcity of commercially made PPE, and the shortage of foresight that caused us to be in such a position of scarcity, is probably why we initially received this messaging of “Masks don’t work!” They do, of us just didn’t want you to understand it for a while, to avoid a run on masks. Think of the empty cabinets in supermarkets across America the place rest room paper used to live, and you understand why.

The simplest thing you are able to do to mask NOW are to make use of materials around the house. Get artistic; anything that covers the mouth and nostril and stays in place will work.

While it’s greatest if the masks fits well and there are no gaps between your face and the outside air, don’t hand over on your homemade mask should you can’t achieve that. Any face covering will maintain you from touching the skin around your nose and mouth directly, which might turn out to be the most important mechanism by which masks block virus transmission. For those who inadvertently contact your face while you’re wearing a mask, you’ll just contact the mask, not your skin.

You’ll be able to try to form your face covering using pipe cleaners or opened-up rubber-coated paper clips within the half that goes over your nose to make a tighter match — experiment. A very powerful thing is that you just wash your palms, put on your face covering, and exit of the house protected.
