Full Guide to Wearing Face Masks

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

Why?

Because they work.

Research from the SARS outbreak in 2003 shows that washing hands 10+ times day by day was fifty five% efficient in stopping virus transmission; wearing a mask was really more efficient, reducing transmission by about 68%.

Combining a number of types of protection — hand washing, mask wearing, gloves, and another layer of outerwear (gowning) — was 91% effective.

Read that again: 91% effective at stopping virus transmission.

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

Masks work, first, because they're a physical barrier to no matter’s riding along on that air you’re breathing or moving through. Right here’s a chart showing the relative barrier effectiveness for various supplies:

Secondly, they work because they hold you from touching your face all day long. The mask makes you more self-acutely aware of the truth that you’re not supposed to the touch your face- specifically, your mouth, nose, and eyes, and the areas round them- and for those who by accident do, you’ll touch the masks, not your skin directly.

Third, the experience of other countries who mask show that masks work in the real world. In the words of Jeremy Howard, researcher and Masks4All activist, explaining a chart in his recent Youtube video showing how some international locations have successfully "flattened the curve" on new infections: "In the event you have a look at all the international locations which have flat curves, they are countries where mask-wearing is extraordinarily normal, and NOT wearing a mask in places like public transport can be considered anti-social." He notes that the Czech Republic went from zero mask usage to 100% in 10 days, and in the process they halted the expansion 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 an area outbreak case on January 22 through the peak Lunar New Year journey season. A sick individual on the bus who did not work together with anyone spread the virus to 7 others, some of whom were seated much more than 6 ft away. Two new passengers caught the virus half-hour after the original sick particular 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 the place individuals were sitting on the bus.

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

First, please don’t buy masks commercially, if by some miracle you could possibly discover them now. Commercially made PPE should be reserved for medical personnel at this time. Unfortunately, the scarcity of commercially made PPE, and the lack of foresight that caused us to be in such a place 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 realize it for a while, to keep away from a run on masks. Think of the empty cabinets in supermarkets across America the place toilet paper used to live, and you understand why.

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

While it’s best if the mask suits well and there aren't any gaps between your face and the outside air, don’t give up in your homemade masks in the event you can’t achieve that. Any face covering will maintain you from touching the skin round your nose and mouth directly, which could transform the most important mechanism by which masks block virus transmission. When you inadvertently touch your face while you’re wearing a masks, you’ll just contact the masks, not your skin.

You may try to form your face covering utilizing pipe cleaners or opened-up rubber-coated paper clips in the part that goes over your nose to make a tighter fit — experiment. Crucial thing is that you just wash your hands, put on your face covering, and go out of the house protected.
