The New York Occasions and Washington Post have now come around to a position 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.
Why?
Because they work.
Analysis from the SARS outbreak in 2003 shows that washing palms 10+ occasions day by day was 55% efficient in stopping virus transmission; wearing a mask was truly more effective, reducing transmission by about 68%.
Combining a number of types 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 comparable types of viruses (coronaviruses), and it is smart 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 whatever’s riding along on that air you’re breathing or moving through. Here’s a chart showing the relative barrier effectiveness for numerous materials:
Secondly, they work because they maintain you from touching your face all day long. The mask makes you more self-acutely aware of the fact that you’re not supposed to the touch your face- specifically, your mouth, nose, and eyes, and the areas around them- and in case you by chance do, you’ll touch the mask, not your skin directly.
Third, the expertise of other nations who mask show that masks work in the real world. Within the words of Jeremy Howard, researcher and Masks4All activist, explaining a chart in his current Youtube video showing how some countries have successfully “flattened the curve” on new infections: “In the event you have a look at all of the countries which have flat curves, they’re nations the place mask-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 expansion of new covid-19 cases. The Czechs made their own masks- the government didn’t give them out.
If you still should be persuaded, take a look at this Chinese research of an area outbreak case on January 22 in the course of the peak Lunar New Year journey season. A sick person on the bus who did not work together with anyone spread the virus to 7 others, some of whom have been seated much more than 6 ft away. Two new passengers caught the virus half-hour after the unique 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 where folks were sitting on the bus.
So let’s say you’re satisfied, and now you’re thinking of some kind of face covering. What are your options?
First, please don’t buy masks commercially, if by some miracle you can discover them now. Commercially made PPE should 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 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 avoid a run on masks. Think of the empty shelves in supermarkets across America the place bathroom paper used to live, and also you perceive why.
The simplest thing you are able to do to masks NOW are to use materials across the house. Get artistic; 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 on your homemade mask should you can’t achieve that. Any face covering will hold you from touching the skin around your nostril and mouth directly, which might turn out to be an important mechanism by which masks block virus transmission. When you inadvertently touch your face while you’re wearing a mask, you’ll just touch the mask, not your skin.
You can attempt to form your face covering utilizing pipe cleaners or opened-up rubber-coated paper clips within the half that goes over your nostril to make a tighter fit — experiment. An important thing is that you simply wash your arms, put on your face covering, and exit of the house protected.
