Full Guide to Wearing Face Masks

The New York Occasions and Washington Post have now come around to a position I advocated for right here on Medium last week: We should all be wearing masks. Not just health care workers, but ALL of us. Whenever we go out in public.
Why?
Because they work.
Analysis from the SARS outbreak in 2003 shows that washing arms 10+ occasions every day was fifty five% efficient in stopping virus transmission; wearing a mask was really more efficient, reducing transmission by about sixty eight%.
Combining multiple types of protection — hand washing, mask wearing, gloves, and another layer of outerwear (gowning) — was 91% effective.
Read that once more: 91% efficient at stopping virus transmission.
COVID-19 and SARS are related types of viruses (coronaviruses), and it is smart 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 preserve you from touching your face all day long. The masks makes you more self-acutely 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 when you accidentally do, you’ll touch the mask, not your skin directly.
Third, the experience of different nations who mask show that masks work within the real world. Within the words of Jeremy Howard, researcher and Masks4All activist, explaining a chart in his latest Youtube video showing how some international locations have successfully “flattened the curve” on new infections: “For those who take a look at all the international locations which have flat curves, they’re countries where mask-wearing is extremely normal, and NOT wearing a masks in places like public transport would be considered anti-social.” He notes that the Czech Republic went from zero mask utilization to a hundred% in 10 days, and within the process they halted the growth of new covid-19 cases. The Czechs made their own masks- the government didn’t give them out.

Should you still should be persuaded, check out this Chinese study of a local outbreak case on January 22 during the peak Lunar New Year journey season. A sick person on the bus who did not work together with anyone spread the virus to 7 others, a few of whom had been seated much 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 precisely where individuals were sitting on the bus.
So let’s say you’re satisfied, and now you’re thinking of some sort of face covering. What are your options?
First, please don’t purchase masks commercially, if by some miracle you could possibly find them now. Commercially made PPE must 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 position of shortage, is probably why we initially obtained this messaging of “Masks don’t work!” They do, of us just didn’t want you to comprehend it for a while, to avoid a run on masks. Think of the empty cabinets in supermarkets throughout America where toilet paper used to live, and you understand why.
The easiest thing you are able to do to mask NOW are to make use of supplies around the house. Get inventive; anything that covers the mouth and nose and stays in place will work.

While it’s greatest if the masks suits well and there are no gaps between your face and the outside air, don’t surrender in your homemade mask if you can’t achieve that. Any face covering will keep you from touching the skin round your nostril and mouth directly, which may turn out to be the most important mechanism by which masks block virus transmission. In the event you inadvertently contact your face while you’re wearing a masks, you’ll just contact the masks, not your skin.
You can attempt to form your face covering using pipe cleaners or opened-up rubber-coated paper clips in the half that goes over your nose to make a tighter fit — experiment. Crucial thing is that you wash your fingers, put in your face covering, and go out of the house protected.
