The New York Times 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. Every time we exit in public.
Why?
Because they work.
Research from the SARS outbreak in 2003 shows that washing palms 10+ occasions every day was 55% effective in stopping virus transmission; wearing a masks was really more efficient, reducing transmission by about 68%.
Combining multiple types of protection — hand washing, mask wearing, gloves, and one other layer of outerwear (gowning) — was ninety one% effective.
Read that once more: 91% effective 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 stop transmission of the other.
Masks work, first, because they are a physical barrier to whatever’s driving 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-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 unintentionally do, you’ll contact the mask, not your skin directly.
Third, the expertise of different international locations 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 recent Youtube video showing how some countries have successfully "flattened the curve" on new infections: "If you take a look at all of the nations which have flat curves, they are countries the place mask-wearing is extremely normal, 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 government didn’t give them out.


In the event you nonetheless have to be persuaded, check out this Chinese research of a neighborhood outbreak case on January 22 in the course of the peak Lunar New Year journey season. A sick person on the bus who didn't interact with anybody spread the virus to 7 others, a few of whom have been seated much more than 6 ft away. Two new passengers caught the virus 30 minutes 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 the place people were 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 might 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 shortage, is probably why we initially obtained this messaging of "Masks don’t work!" They do, folks just didn’t need you to realize it for a while, to keep away from a run on masks. Think of the empty shelves in supermarkets across America where toilet paper used to live, and you perceive why.
The easiest thing you are able to do to mask NOW are to make use of supplies around the house. Get creative; anything that covers the mouth and nostril and stays in place will work.

While it’s greatest if the mask matches well and there are not any gaps between your face and the outside air, don’t quit on your homemade masks if you happen to can’t achieve that. Any face covering will maintain you from touching the skin round your nostril and mouth directly, which may turn out to be crucial mechanism by which masks block virus transmission. If you happen to inadvertently contact your face while you’re wearing a mask, you’ll just touch the mask, not your skin.
You'll be able to try to form your face covering utilizing pipe cleaners or opened-up rubber-coated paper clips in the half that goes over your nose to make a tighter match — experiment. An important thing is that you simply wash your palms, put in your face covering, and go out of the house protected.
