The New York Instances and Washington Post have now come around to a place I advocated for right here on Medium last week: We should all be wearing masks. Not just health care workers, but ALL of us. Each time we exit in public.
Because they work.
Analysis from the SARS outbreak in 2003 shows that washing fingers 10+ instances each day was 55% effective in stopping virus transmission; wearing a mask was actually more effective, reducing transmission by about 68%.
Combining a number of forms of protection — hand washing, masks wearing, gloves, and another 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 is smart that what works to cease transmission for one will work to stop transmission of the other.
Masks work, first, because they are a physical barrier to whatever’s riding 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 hold you from touching your face all day long. The masks makes you more self-conscious of the truth that you’re not supposed to touch your face- specifically, your mouth, nose, and eyes, and the areas round them- and if you happen to by accident do, you’ll contact the masks, not your skin directly.
Third, the expertise of different countries 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 countries have efficiently “flattened the curve” on new infections: “If you happen to look at all of the nations which have flat curves, they’re nations the place masks-wearing is extremely 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 utilization to 100% in 10 days, and in the process they halted the expansion of new covid-19 cases. The Czechs made their own masks- the federal government didn’t give them out.
For those who still need to be persuaded, check out this Chinese research of an area outbreak case on January 22 throughout the peak Lunar New Year journey season. A sick particular person on the bus who did not work together 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 30 minutes after the original 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 precisely the place 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 purchase masks commercially, if by some miracle you could find them now. Commercially made PPE ought to be reserved for medical personnel at this time. Unfortunately, the shortage of commercially made PPE, and the lack of foresight that caused us to be in such a place of scarcity, is probably why we initially bought this messaging of “Masks don’t work!” They do, people just didn’t want you to know it for a while, to keep away from a run on masks. Think of the empty shelves in supermarkets throughout America where rest room paper used to live, and also you perceive why.
The best thing you can do to mask NOW are to use materials around the house. Get artistic; anything that covers the mouth and nose and stays in place will work.
While it’s greatest if the masks fits well and there are no gaps between your face and the outside air, don’t quit on your homemade mask should you can’t achieve that. Any face covering will keep you from touching the skin round your nostril and mouth directly, which may transform an important mechanism by which masks block virus transmission. Should you inadvertently contact your face while you’re wearing a masks, you’ll just contact the mask, not your skin.
You may try to form your face covering using pipe cleaners or opened-up rubber-coated paper clips in the part that goes over your nose to make a tighter fit — experiment. An important thing is that you wash your hands, put on your face covering, and exit of the house protected.
