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 always all be wearing masks. Not just health care workers, however ALL of us. Every time we go out in public.
Because they work.
Research from the SARS outbreak in 2003 shows that washing palms 10+ instances every day was fifty five% effective in stopping virus transmission; wearing a masks was truly more efficient, reducing transmission by about 68%.
Combining multiple forms of protection — hand washing, masks wearing, gloves, and another layer of outerwear (gowning) — was ninety one% effective.
Read that again: ninety one% efficient at stopping virus transmission.
COVID-19 and SARS are comparable types of viruses (coronaviruses), and it makes sense 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 no matter’s riding along on that air you’re breathing or moving through. Right here’s a chart showing the relative barrier effectiveness for varied 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 in case you by chance do, you’ll touch the mask, not your skin directly.
Third, the expertise of different nations 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 international locations have efficiently «flattened the curve» on new infections: «When you look at all of the international locations which have flat curves, they are nations the place masks-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 a 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 should be persuaded, check out this Chinese examine of an area outbreak case on January 22 through the peak Lunar New Year travel 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 a lot more than 6 ft away. Two new passengers caught the virus half-hour 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 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 purchase masks commercially, if by some miracle you can 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 lack of foresight that caused us to be in such a position of scarcity, is probably why we initially bought this messaging of «Masks don’t work!» They do, people 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 the place bathroom paper used to live, and also you perceive why.
The best thing you are able to do to masks 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 best if the mask fits well and there are no gaps between your face and the outside air, don’t give up on your homemade mask if you can’t achieve that. Any face covering will keep you from touching the skin around your nostril and mouth directly, which could change into the most important mechanism by which masks block virus transmission. If you inadvertently touch your face while you’re wearing a masks, you’ll just touch the masks, not your skin.
You may attempt to shape your face covering utilizing pipe cleaners or opened-up rubber-coated paper clips within the part that goes over your nose to make a tighter match — experiment. The most important thing is that you simply wash your fingers, put on your face covering, and go out of the house protected.
