The New York Instances and Washington Post have now come round to a position I advocated for here on Medium last week: We must 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 arms 10+ times every day was 55% effective in stopping virus transmission; wearing a masks was actually more effective, reducing transmission by about sixty eight%.
Combining multiple types of protection — hand washing, masks wearing, gloves, and one other layer of outerwear (gowning) — was ninety one% effective.
Read that again: ninety one% effective at stopping virus transmission.
COVID-19 and SARS are similar types of viruses (coronaviruses), and it is smart that what works to stop transmission for one will work to stop transmission of the other.
Masks work, first, because they’re 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 various supplies:
Secondly, they work because they keep you from touching your face all day long. The masks makes you more self-conscious of the fact that you’re not supposed to the touch your face- specifically, your mouth, nostril, and eyes, and the areas around them- and for those who accidentally do, you’ll touch the masks, not your skin directly.
Third, the expertise of other nations 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 countries have efficiently “flattened the curve” on new infections: “If you take a look at all the international locations which have flat curves, they’re international locations where 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 mask utilization to one hundred% in 10 days, and within 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.
If you happen to still must be persuaded, check out this Chinese study of a neighborhood outbreak case on January 22 through the peak Lunar New Year journey season. A sick particular person on the bus who did not interact with anyone spread the virus to 7 others, some of whom had 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 exactly the place folks have 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 would discover them now. Commercially made PPE ought to be reserved for medical personnel at this time. Sadly, the scarcity of commercially made PPE, and the shortage of foresight that caused us to be in such a position of scarcity, is probably why we initially acquired this messaging of “Masks don’t work!” They do, folks 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 you perceive why.
The best thing you are able to do to mask NOW are to use supplies across the house. Get creative; anything that covers the mouth and nostril and stays in place will work.
While it’s best 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 mask should you can’t achieve that. Any face covering will keep you from touching the skin around your nose and mouth directly, which might become the most important mechanism by which masks block virus transmission. If you happen to inadvertently touch your face while you’re wearing a masks, you’ll just contact the masks, not your skin.
You can try 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 match — experiment. Crucial thing is that you just wash your palms, put in your face covering, and go out of the house protected.
