That is the question. Do surgical masks do any good? Or as many ‘authorities’ like Canada’s Federal chief medical honcho keep telling us, masks are baaad and raaacist and your legs will drop off if wear one.
Well, I look at the public health ‘advice’ out there and I’m having a bad case of “WTF?” Finding advice given over the mass media often contradictory and downright bad. Especially if you want to avoid spreading or contracting any form of lurgi.
Declaration of interest here. I’ve done basic operating theatre training and a six weeks placement assisting with a number of operations from tonsilectomies to hip replacements. So I’m not entirely ignorant. Okay, much of my experience is dated, but the basics are pretty simple and haven’t changed that much.
Ask yourself this;
Q: Why do operating theatre staff wear disposable paper deflector masks rather than filter masks?
A: To prevent them breathing germs over open wounds.
You see, I was taught that the purpose of a surgical mask is to slow and direct breathed (and infected) air away from the area being operated upon. This is why the one time I picked up a filter mask because we were running low on the soft surgical variety, the Senior Sister on duty tore me off a serious strip and sent me back to the scrub area to get a proper surgical mask and wash up again. That woman had a tongue that could scour rust. Hey, but she was old school and her lessons stuck.
Her lesson was that filter masks are not that useful in containing viruses, especially when containing coughs and sneezes, because a little expressed airflow still escapes over the area you want to keep clear of infection and viruses can pass through even an N95. With a soft surgical mask the ever present germs from your breath tend to be directed behind the mask and not over someone else whilst still allowing you to breathe freely. That is why they work.
Which if containing diseases is the effect you are looking for, surgical masks are quite the thing. You can even make your own if the stores are out, which at the moment is probable. Pattern here if you’re handy with a sewing machine. Or watch the video below (Sorry about the accent, she’s American, poor lamb). A normal Kleenex will do for a disposable insert. Make a few and give them to your friends. Sell them to your enemies. At top dollar.
This isn’t an April fools by the way.
To reiterate; in terms of restricting infection spread a soft surgical style mask does not have to be tight fitting and fulfills it’s function pretty well even if worn over a beard. A scarf over the face works too. Anything that slows droplets expressed during a cough or sneeze (Or even excited talking) will do at a pinch. A scarf or large bandanna tied over the face while you’re out and about mitigates the worst of the spread simply because it reduces the radius of potential infection to centimetres rather than two metres. Cotton or viscose will do. Don’t forget to wash after each use. Cover your mouth with paper tissues or even an old fashioned handkerchief if you have nothing else. Japanese and Koreans wear masks a lot, and their infection stats are much lower than those in the Anglophone west. We should profit from their example.
Conclusion; masks aren’t bad. They’re quite good, no matter what the PTB say. To say otherwise is monumentally bad advice, especially when it comes to preventing the spread of a nasty disease like SARS-CoVD 19. Add a mask to decent hygiene and cheap non-latex gloves you will maximise your chances of coming through this pandemic relatively unscathed when out and about, going to work or the stores.
So long as Security think you’re not trying to rob the place and call the cops on you, you’ll be fine.
