Complete Guide to Wearing Face Masks

April 26, 2020 business

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


Because they work.

Analysis from the SARS outbreak in 2003 shows that washing arms 10+ instances daily was 55% effective in stopping virus transmission; wearing a masks was actually more effective, reducing transmission by about 68%.

Combining a number of forms of protection — hand washing, mask wearing, gloves, and another layer of outerwear (gowning) — was ninety one% effective.

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

COVID-19 and SARS are comparable types of viruses (coronaviruses), and it makes sense that what works to stop transmission for one will work to stop transmission of the other.

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

Secondly, they work because they maintain you from touching your face all day long. The masks makes you more self-aware of the truth that you’re not supposed to touch your face- specifically, your mouth, nose, and eyes, and the areas round them- and if you happen to unintentionally do, you’ll contact the masks, not your skin directly.

Third, the expertise of other international locations who masks show that masks work in the real world. In the words of Jeremy Howard, researcher and Masks4All activist, explaining a chart in his current Youtube video showing how some countries have efficiently “flattened the curve” on new infections: “If you happen to have a look at all the international locations which have flat curves, they’re countries the place 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 usage to 100% in 10 days, and within the process they halted the growth of new covid-19 cases. The Czechs made their own masks- the federal government didn’t give them out.

In case you nonetheless should be persuaded, take a look at this Chinese examine of a local outbreak case on January 22 during the peak Lunar New Year travel season. A sick particular person on the bus who did not work together with anybody spread the virus to 7 others, some of whom had been seated a lot more than 6 ft away. Two new passengers caught the virus 30 minutes after the unique 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 precisely where individuals were 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 can find them now. Commercially made PPE ought to 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 place of scarcity, is probably why we initially obtained this messaging of “Masks don’t work!” They do, folks just didn’t need you to realize it for a while, to keep away from a run on masks. Think of the empty shelves in supermarkets across America the place bathroom 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 across the house. Get inventive; anything that covers the mouth and nose and stays in place will work.

While it’s best if the mask fits well and there aren’t any gaps between your face and the outside air, don’t surrender on your homemade mask in case you can’t achieve that. Any face covering will maintain you from touching the skin round your nostril and mouth directly, which could transform an important mechanism by which masks block virus transmission. In case you inadvertently contact your face while you’re wearing a masks, you’ll just touch the mask, not your skin.

You possibly can try to shape your face covering using pipe cleaners or opened-up rubber-coated paper clips within the part that goes over your nose to make a tighter fit — experiment. An important thing is that you wash your hands, put on your face covering, and go out of the house protected.
