The New York Times and Washington Post have now come round to a position I advocated for right here on Medium last week: We should all be wearing masks. Not just health care workers, however ALL of us. Each time we go out in public.
Why?
Because they work.
Analysis from the SARS outbreak in 2003 shows that washing palms 10+ times each day was fifty five% effective in stopping virus transmission; wearing a mask was actually more efficient, 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 ninety one% effective.
Read that once more: 91% effective at stopping virus transmission.
COVID-19 and SARS are related types of viruses (coronaviruses), and it is smart that what works to cease transmission for one will work to stop transmission of the other.
Masks work, first, because they’re a physical barrier to whatever’s driving along on that air you’re breathing or moving through. 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-acutely aware of the fact that you’re not supposed to the touch your face- specifically, your mouth, nostril, and eyes, and the areas around them- and if you happen to by chance do, you’ll touch the mask, not your skin directly.
Third, the experience of other international locations 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 countries have successfully “flattened the curve” on new infections: “If you happen to have a look at all of the countries which have flat curves, they’re nations the place mask-wearing is extraordinarily regular, and NOT wearing a masks in places like public transport can be considered anti-social.” He notes that the Czech Republic went from zero mask usage to one hundred% in 10 days, and within the process they halted the expansion of new covid-19 cases. The Czechs made their own masks- the government didn’t give them out.
Should you nonetheless must be persuaded, take a look at this Chinese examine of a local outbreak case on January 22 during the peak Lunar New Year journey season. A sick person on the bus who didn’t interact with anyone 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 half-hour after the unique 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 where individuals had been 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 may discover them now. Commercially made PPE ought to 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 scarcity, is probably why we initially acquired this messaging of “Masks don’t work!” They do, of us just didn’t need you to know it for a while, to keep away from a run on masks. Think of the empty cabinets in supermarkets across America where rest room paper used to live, and you perceive why.
The simplest thing you can do to mask NOW are to use materials around the house. Get artistic; anything that covers the mouth and nostril and stays in place will work.
While it’s finest if the mask fits well and there aren’t any gaps between your face and the outside air, don’t surrender in your homemade mask in case you can’t achieve that. Any face covering will preserve you from touching the skin around your nose and mouth directly, which could turn into crucial mechanism by which masks block virus transmission. In the event you inadvertently touch your face while you’re wearing a mask, you’ll just contact the masks, not your skin.
You can try to form your face covering utilizing pipe cleaners or opened-up rubber-coated paper clips within the half that goes over your nostril to make a tighter fit — experiment. A very powerful thing is that you wash your fingers, put in your face covering, and go out of the house protected.
