Fact Check There is no evidence masks work.
Of course there is. Why is it that you repeatedly get so hot and bothered
by stuff like this? What's it got to do with you whether or not other people
choose to wear a mask anyway? Nobody's forcing
you to wear a mask, so
what's your problem exactly?

Quote:Consistent use of a face mask or respirator in indoor public settings was
associated with lower odds of a positive SARS-CoV-2 test result (adjusted
odds ratio = 0.44). Use of respirators with higher filtration capacity was
associated with the most protection, compared with no mask use.
Lets just use our common sense here. The claim being made here, is that people who wear masks in public indoor settings are
LESS LIKELY, or the
ODDS ARE LOWER, for them to test positive for Covid-19. Could any claim be any more vague, ambiguous, or obscure as this??
Does this mean that people wearing masks NOT in public indoor settings, ARE more likely to test positive for Covid-19? Also, since over 95% of the Australians population continue to test negative for Covid-19 anyway, I'd love to see just how this study was conducted.
There is absolutely no causal relationship between the two events. I could just as easily say that people with no facial hair are
less likely to test positive to Covid-19. And, I would be right. But again, I can't explain any direct causal relationship between wearing masks, and the settings where the masks are worn. Or, not worn. I have nothing to support this unwarranted assumption!
But lets look at the scientific facts regarding the efficacy and protection claims being made by mask manufacturers.
Firstly, the smallest SARS-CoV-2 virus is around 0.05 microns. The smallest pore size on any filtration masks is between 0.1 and 0.3 microns(2 to 5 times larger). So, you do the math!
Secondly, even the P2/N95 masks are useless if they are not worn correctly. And, no mask will ever fit perfectly on any face, all the time. Also, lets not forget that the SARS-CoV-2 virus can enter the body through the eyes(ocular mucosa).

Finally, The droplets from a sneeze or cough, can contain as many as 200M viral particles. Even if we assume that the N95 mask will provide 95% protection from airborne viruses(which it doesn't), that would still allow around 10M viruses to pass through. It only takes a few hundred, to a thousand viruses to infect you. So, if you can find a mask with a protection level of 99.999999%(200 viruses pass through), then get it. Also, you might want to wear eye shields($195.40AUD) just to be sure.
