The New York Instances and Washington Post have now come around 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. At any time when we go out in public.
Because they work.
Research from the SARS outbreak in 2003 shows that washing palms 10+ occasions every day was 55% efficient in stopping virus transmission; wearing a masks was really more effective, reducing transmission by about 68%.
Combining multiple forms of protection — hand washing, masks wearing, gloves, and one other layer of outerwear (gowning) — was 91% effective.
Read that once more: ninety one% efficient at stopping virus transmission.
COVID-19 and SARS are comparable types of viruses (coronaviruses), and it is sensible that what works to cease 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 along on that air you’re breathing or moving through. Right here’s a chart showing the relative barrier effectiveness for various supplies:
Secondly, they work because they preserve you from touching your face all day long. The mask 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 should you by accident do, you’ll contact the mask, not your skin directly.
Third, the expertise of other international locations who masks show that masks work in the real world. In the words of Jeremy Howard, researcher and Masks4All activist, explaining a chart in his current Youtube video showing how some nations have successfully “flattened the curve” on new infections: “When you look at all of the international locations which have flat curves, they’re international locations the place masks-wearing is extraordinarily 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 utilization 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 federal government didn’t give them out.
In the event you nonetheless must be persuaded, check out this Chinese study of a local outbreak case on January 22 during the peak Lunar New Year journey season. A sick particular person on the bus who did not interact with anybody spread the virus to 7 others, a few of whom were seated much more than 6 ft away. Two new passengers caught the virus half-hour after the original 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 where people have been sitting on the bus.
So let’s say you’re satisfied, and now you’re thinking of some type 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 scarcity of commercially made PPE, and the dearth of foresight that caused us to be in such a place of scarcity, is probably why we initially got this messaging of “Masks don’t work!” They do, of us just didn’t need you to comprehend it for a while, to avoid a run on masks. Think of the empty cabinets in supermarkets across America where bathroom paper used to live, and also you understand why.
The easiest thing you are able to do to masks NOW are to use supplies around the house. Get inventive; anything that covers the mouth and nostril and stays in place will work.
While it’s greatest if the mask matches well and there aren’t any gaps between your face and the outside air, don’t hand over in your homemade masks should you can’t achieve that. Any face covering will hold you from touching the skin around your nose and mouth directly, which might grow to be an important mechanism by which masks block virus transmission. In the event you inadvertently touch your face while you’re wearing a masks, you’ll just contact the mask, not your skin.
You possibly can attempt to form your face covering using pipe cleaners or opened-up rubber-coated paper clips in the half that goes over your nose to make a tighter fit — experiment. Crucial thing is that you simply wash your fingers, put in your face covering, and go out of the house protected.
