The New York Times and Washington Post have now come around to a place I advocated for right here on Medium final week: We should always all be wearing masks. Not just health care workers, but ALL of us. At any time when we exit in public.
Because they work.
Research from the SARS outbreak in 2003 shows that washing arms 10+ occasions day by day was fifty five% efficient in stopping virus transmission; wearing a masks was actually more effective, reducing transmission by about 68%.
Combining multiple types of protection — hand washing, mask wearing, gloves, and another layer of outerwear (gowning) — was ninety one% 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 stop transmission for one will work to cease transmission of the other.
Masks work, first, because they are a physical barrier to no matter’s using alongside on that air you’re breathing or moving through. Here’s a chart showing the relative barrier effectiveness for varied supplies:
Secondly, they work because they maintain you from touching your face all day long. The masks makes you more self-conscious of the fact that you’re not supposed to touch your face- specifically, your mouth, nose, and eyes, and the areas around them- and should you accidentally do, you’ll contact the masks, not your skin directly.
Third, the experience of other international locations 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 latest Youtube video showing how some international locations have successfully "flattened the curve" on new infections: "Should you take a look at all the international locations which have flat curves, they are countries the place masks-wearing is extraordinarily regular, and NOT wearing a mask in places like public transport would be considered anti-social." He notes that the Czech Republic went from zero masks usage 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 nonetheless should be persuaded, take a look at this Chinese study of a neighborhood outbreak case on January 22 in the course of the peak Lunar New Year travel season. A sick individual on the bus who didn't interact with anyone spread the virus to 7 others, a few of whom have been seated much 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 the place folks had been 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 could find them now. Commercially made PPE needs to be reserved for medical personnel at this time. Sadly, 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 obtained this messaging of "Masks don’t work!" They do, folks just didn’t want you to know it for a while, to avoid a run on masks. Think of the empty shelves in supermarkets throughout America where bathroom paper used to live, and you understand why.
The easiest thing you can do to mask NOW are to make use of supplies across the house. Get creative; anything that covers the mouth and nostril and stays in place will work.
While it’s finest if the mask suits well and there are not any gaps between your face and the outside air, don’t give up in your homemade masks for those who can’t achieve that. Any face covering will preserve you from touching the skin round your nose and mouth directly, which could turn out to be the most important mechanism by which masks block virus transmission. When you inadvertently touch your face while you’re wearing a mask, you’ll just touch 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 nostril to make a tighter fit — experiment. A very powerful thing is that you wash your palms, put on your face covering, and exit of the house protected.
