The New York Times and Washington Post have now come around 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. Every time we exit in public.
Because they work.
Analysis from the SARS outbreak in 2003 shows that washing arms 10+ instances every day was fifty five% efficient in stopping virus transmission; wearing a mask was actually more effective, reducing transmission by about sixty eight%.
Combining a number of forms of protection — hand washing, masks wearing, gloves, and another 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 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 driving along on that air you’re breathing or moving through. Here’s a chart showing the relative barrier effectiveness for various materials:
Secondly, they work because they hold you from touching your face all day long. The masks makes you more self-acutely aware of the fact that you’re not supposed to touch your face- specifically, your mouth, nose, and eyes, and the areas around them- and if you accidentally do, you’ll contact the masks, not your skin directly.
Third, the expertise of different international locations who mask show that masks work within 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 successfully « 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 where masks-wearing is extraordinarily normal, and NOT wearing a masks in places like public transport can be considered anti-social. » He notes that the Czech Republic went from zero masks usage to one hundred% in 10 days, and within the process they halted the growth of new covid-19 cases. The Czechs made their own masks- the government didn’t give them out.
If you happen to still have to be persuaded, check out this Chinese examine of an area outbreak case on January 22 in the course of the peak Lunar New Year travel season. A sick individual on the bus who didn’t interact with anybody spread the virus to 7 others, some of whom were seated a lot 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 individuals had 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 could 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 shortage of foresight that caused us to be in such a position of shortage, is probably why we initially received this messaging of « Masks don’t work! » They do, people 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 throughout America the place bathroom paper used to live, and you understand why.
The easiest thing you can do to masks NOW are to make use of materials across the house. Get artistic; anything that covers the mouth and nose and stays in place will work.
While it’s best if the mask suits well and there are not any gaps between your face and the outside air, don’t quit in your homemade mask should you can’t achieve that. Any face covering will preserve you from touching the skin around your nose and mouth directly, which may grow to be the most important mechanism by which masks block virus transmission. In case you inadvertently touch your face while you’re wearing a mask, you’ll just touch the mask, not your skin.
You can attempt to shape your face covering utilizing pipe cleaners or opened-up rubber-coated paper clips within the part that goes over your nostril to make a tighter fit — experiment. A very powerful thing is that you simply wash your arms, put in your face covering, and go out of the house protected.
