Full Guide to Wearing Face Masks

The New York Instances and Washington Post have now come around to a position I advocated for right here on Medium final week: We must always all be wearing masks. Not just health care workers, but ALL of us. Each time we go out in public.
Why?
Because they work.
Research from the SARS outbreak in 2003 shows that washing fingers 10+ occasions every day was fifty five% efficient in stopping virus transmission; wearing a mask was actually more efficient, reducing transmission by about sixty eight%.
Combining multiple types of protection — hand washing, mask wearing, gloves, and one other layer of outerwear (gowning) — was ninety one% effective.
Read that once more: ninety one% efficient at stopping virus transmission.
COVID-19 and SARS are related 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 are a physical barrier to no matter’s riding alongside on that air you’re breathing or moving through. Right here’s a chart showing the relative barrier effectiveness for numerous supplies:

Secondly, they work because they maintain you from touching your face all day long. The mask makes you more self-conscious of the truth that you’re not supposed to touch your face- specifically, your mouth, nostril, and eyes, and the areas around them- and should you by accident do, you’ll touch the mask, not your skin directly.
Third, the expertise of other nations 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 efficiently “flattened the curve” on new infections: “When you look at all the nations which have flat curves, they are international locations the place masks-wearing is extraordinarily normal, and NOT wearing a mask in places like public transport could be considered anti-social.” He notes that the Czech Republic went from zero mask usage to a hundred% 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.

Should you nonetheless have to be persuaded, take a look at this Chinese research of an area outbreak case on January 22 through the peak Lunar New Year journey season. A sick individual on the bus who didn’t work together with anybody spread the virus to 7 others, a few of whom were seated a lot more than 6 ft away. Two new passengers caught the virus 30 minutes after the unique sick individual 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 folks were sitting on the bus.
So let’s say you’re satisfied, and now you’re thinking of some kind of face covering. What are your options?
First, please don’t buy masks commercially, if by some miracle you may find them now. Commercially made PPE must be reserved for medical personnel at this time. Unfortunately, the shortage of commercially made PPE, and the shortage of foresight that caused us to be in such a place of shortage, is probably why we initially obtained this messaging of “Masks don’t work!” They do, people just didn’t need you to realize it for a while, to keep away from a run on masks. Think of the empty cabinets in supermarkets throughout America where rest room paper used to live, and also you understand why.
The simplest thing you can do to mask NOW are to use materials across the house. Get artistic; anything that covers the mouth and nose and stays in place will work.

While it’s greatest if the masks fits well and there are not any gaps between your face and the outside air, don’t hand over in your homemade masks if you can’t achieve that. Any face covering will hold you from touching the skin around your nostril and mouth directly, which may 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 contact the masks, not your skin.
You possibly can try to shape your face covering utilizing pipe cleaners or opened-up rubber-coated paper clips within the part that goes over your nose to make a tighter match — experiment. The most important thing is that you wash your arms, put on your face covering, and go out of the house protected.
