The New York Times and Washington Post have now come round to a place I advocated for here on Medium final week: We should always all be wearing masks. Not just health care workers, but ALL of us. Whenever we exit in public.
Because they work.
Analysis from the SARS outbreak in 2003 shows that washing hands 10+ times each day was 55% efficient in stopping virus transmission; wearing a mask was really more effective, reducing transmission by about sixty eight%.
Combining a number of 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're a physical barrier to no matter’s driving 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 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, nostril, and eyes, and the areas round them- and when you by chance do, you’ll contact the masks, not your skin directly.
Third, the expertise of other nations who mask show that masks work in the real world. Within the words of Jeremy Howard, researcher and Masks4All activist, explaining a chart in his latest Youtube video showing how some nations have successfully "flattened the curve" on new infections: "In case you take a look at all of the nations which have flat curves, they're international locations 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 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 government didn’t give them out.
For those who nonetheless must be persuaded, take a look at this Chinese research of an area outbreak case on January 22 throughout the peak Lunar New Year travel season. A sick individual on the bus who did not interact with anyone spread the virus to 7 others, some of whom had been seated much more than 6 ft away. Two new passengers caught the virus half-hour 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 the place people had been 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 buy masks commercially, if by some miracle you can discover them now. Commercially made PPE must be reserved for medical personnel at this time. Sadly, the scarcity of commercially made PPE, and the dearth of foresight that caused us to be in such a position of scarcity, is probably why we initially acquired 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 where bathroom paper used to live, and also you perceive why.
The best thing you are able to do to masks NOW are to use materials around the house. Get inventive; anything that covers the mouth and nose and stays in place will work.
While it’s best if the masks suits well and there aren't any gaps between your face and the outside air, don’t give up in your homemade mask for those who can’t achieve that. Any face covering will preserve you from touching the skin around your nostril and mouth directly, which may develop into a very powerful mechanism by which masks block virus transmission. For those who inadvertently contact your face while you’re wearing a masks, you’ll just touch the mask, not your skin.
You possibly can attempt 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. An important thing is that you just wash your arms, put in your face covering, and exit of the house protected.
