The New York Instances and Washington Post have now come round to a position I advocated for right here on Medium final week: We should always all be wearing masks. Not just health care workers, however ALL of us. Whenever we exit in public.
Why?
Because they work.
Analysis from the SARS outbreak in 2003 shows that washing arms 10+ instances each day was fifty five% efficient in stopping virus transmission; wearing a masks was truly more effective, reducing transmission by about sixty eight%.
Combining a number of forms of protection — hand washing, masks wearing, gloves, and one other layer of outerwear (gowning) — was 91% 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 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 riding alongside 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-aware of the fact 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 touch the mask, not your skin directly.
Third, the expertise of other international locations who mask 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 efficiently “flattened the curve” on new infections: “For those who take a look at all of the international locations which have flat curves, they’re international locations the place mask-wearing is extremely 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 usage to one hundred% in 10 days, and in 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, take a look at this Chinese research of an area outbreak case on January 22 during the peak Lunar New Year journey season. A sick person on the bus who didn’t interact with anyone 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 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 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 may find 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, people 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 toilet paper used to live, and also you understand why.
The best thing you are able to do to masks NOW are to use supplies across 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 are no gaps between your face and the outside air, don’t surrender on your homemade masks in the event you can’t achieve that. Any face covering will keep you from touching the skin around your nose and mouth directly, which may grow to be crucial mechanism by which masks block virus transmission. In case you inadvertently contact your face while you’re wearing a mask, 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 within the part that goes over your nostril to make a tighter fit — experiment. An important thing is that you wash your fingers, put on your face covering, and exit of the house protected.
