The New York Instances and Washington Post have now come around to a place I advocated for here on Medium last week: We must always all be wearing masks. Not just health care workers, but ALL of us. Each time we exit in public.
Why?
Because they work.
Analysis from the SARS outbreak in 2003 shows that washing arms 10+ instances day by day was fifty five% efficient in stopping virus transmission; wearing a masks was actually more effective, reducing transmission by about 68%.
Combining a number of forms of protection — hand washing, mask wearing, gloves, and one other layer of outerwear (gowning) — was ninety one% effective.
Read that once more: 91% efficient at stopping virus transmission.
COVID-19 and SARS are similar types of viruses (coronaviruses), and it makes sense that what works to stop transmission for one will work to cease 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 keep you from touching your face all day long. The masks makes you more self-conscious of the fact that you’re not supposed to touch your face- specifically, your mouth, nostril, and eyes, and the areas around them- and when you unintentionally do, you’ll contact the masks, not your skin directly.
Third, the experience of different nations who masks show that masks work within 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 efficiently “flattened the curve” on new infections: “In case you have a look at all of the countries which have flat curves, they are nations where 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 usage 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 nonetheless should be persuaded, check out this Chinese study of a local outbreak case on January 22 in the course of the peak Lunar New Year travel season. A sick person on the bus who did not interact with anyone spread the virus to 7 others, a few of whom were seated much more than 6 ft away. Two new passengers caught the virus 30 minutes after the unique sick particular 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 where people were sitting on the bus.
So let’s say you’re convinced, and now you’re thinking of some sort of face covering. What are your options?
First, please don’t buy masks commercially, if by some miracle you would discover them now. Commercially made PPE should 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 place of shortage, is probably why we initially obtained this messaging of “Masks don’t work!” They do, people just didn’t need you to know it for a while, to avoid a run on masks. Think of the empty shelves in supermarkets across America where rest room paper used to live, and you perceive why.
The simplest thing you are able to do to mask NOW are to make use of supplies 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 fits well and there are no gaps between your face and the outside air, don’t quit on your homemade mask for those who can’t achieve that. Any face covering will maintain you from touching the skin around your nostril and mouth directly, which might grow to be an important mechanism by which masks block virus transmission. Should you inadvertently touch your face while you’re wearing a masks, you’ll just touch the masks, not your skin.
You may attempt to shape your face covering using pipe cleaners or opened-up rubber-coated paper clips in the part that goes over your nostril 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.
