The New York Occasions and Washington Post have now come round to a place I advocated for right here on Medium last week: We must 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 hands 10+ occasions every day was fifty five% effective in stopping virus transmission; wearing a mask was actually more efficient, reducing transmission by about sixty eight%.
Combining multiple forms of protection — hand washing, masks wearing, gloves, and another layer of outerwear (gowning) — was 91% effective.
Read that once more: 91% efficient at stopping virus transmission.
COVID-19 and SARS are related types of viruses (coronaviruses), and it makes sense that what works to stop transmission for one will work to stop transmission of the other.
Masks work, first, because they are a physical barrier to no matter’s driving alongside 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-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 touch the masks, not your skin directly.
Third, the expertise of other international locations who masks 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 efficiently “flattened the curve” on new infections: “If you happen to have a look at all the international locations which have flat curves, they are nations where masks-wearing is extraordinarily normal, and NOT wearing a mask in places like public transport can be considered anti-social.” He notes that the Czech Republic went from zero masks usage to a hundred% in 10 days, and in the process they halted the growth 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 examine of an area outbreak case on January 22 throughout the peak Lunar New Year journey season. A sick particular person 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 30 minutes after the unique 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 exactly where individuals were sitting on the bus.
So let’s say you’re convinced, 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 find them now. Commercially made PPE needs to be reserved for medical personnel at this time. Sadly, 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 got this messaging of “Masks don’t work!” They do, of us just didn’t want you to understand 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 use supplies around the house. Get creative; anything that covers the mouth and nose and stays in place will work.
While it’s finest if the masks matches well and there are no gaps between your face and the outside air, don’t surrender on your homemade mask in the event you can’t achieve that. Any face covering will preserve you from touching the skin round your nostril and mouth directly, which may turn into the most important mechanism by which masks block virus transmission. For those who inadvertently touch your face while you’re wearing a masks, you’ll just contact the mask, not your skin.
You possibly can try to shape your face covering utilizing pipe cleaners or opened-up rubber-coated paper clips within the half that goes over your nose to make a tighter fit — experiment. The most important thing is that you simply wash your hands, put in your face covering, and exit of the house protected.
