The New York Instances and Washington Post have now come round to a place I advocated for here on Medium last week: We should always 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+ occasions daily was 55% efficient in stopping virus transmission; wearing a masks was actually more efficient, reducing transmission by about sixty eight%.
Combining multiple forms of protection — hand washing, mask wearing, gloves, and one other layer of outerwear (gowning) — was 91% effective.
Read that again: 91% efficient at stopping virus transmission.
COVID-19 and SARS are related types of viruses (coronaviruses), and it makes sense that what works to stop transmission for one will work to cease 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. 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 mask makes you more self-conscious of the truth that you’re not supposed to the touch your face- specifically, your mouth, nostril, and eyes, and the areas round them- and if you happen to by accident do, you’ll touch the masks, not your skin directly.
Third, the experience of different countries 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: “In case you have a look at all of the international locations which have flat curves, they’re countries where masks-wearing is extremely regular, and NOT wearing a mask in places like public transport could be considered anti-social.” He notes that the Czech Republic went from zero masks usage to 100% in 10 days, and within the process they halted the growth of new covid-19 cases. The Czechs made their own masks- the federal government didn’t give them out.
If you still have to 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 particular person on the bus who did not work together 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 30 minutes after the original 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 precisely where folks had been sitting on the bus.
So let’s say you’re convinced, and now you’re thinking of some type 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 should 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 got this messaging of “Masks don’t work!” They do, folks just didn’t want you to realize it for a while, to keep away from a run on masks. Think of the empty shelves in supermarkets throughout America where toilet paper used to live, and you understand why.
The simplest thing you can do to mask NOW are to use supplies 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 matches well and there aren’t any gaps between your face and the outside air, don’t surrender on your homemade mask in case you can’t achieve that. Any face covering will maintain you from touching the skin round your nostril and mouth directly, which might transform the most important mechanism by which masks block virus transmission. For those who inadvertently contact your face while you’re wearing a masks, you’ll just contact the mask, not your skin.
You’ll be able to attempt to shape your face covering utilizing pipe cleaners or opened-up rubber-coated paper clips in the half that goes over your nostril to make a tighter fit — experiment. The most important thing is that you wash your hands, put on your face covering, and go out of the house protected.
