No, you should read what I sent. If everyone wears a mask - even just a cloth mask - it seriously cuts the spread.Well — again — no one here needs to be reminded again of biology and how the virus can be spread. And that was never my question.
To your point — and it’s precisely my whole point of this — unless you’re wearing N95 it’s not making much, if any, difference.
What we have now is most of society walking around with a false sense of security of having a mask — because of the predictable media and social affirmation that “you’re a good person and those not wearing masks are ignorant and selfish”, when in fact most of these mask-wearing people are just as likely spreading Covid because the masks are a sieve for the virus. Couple this with false confidence and flaunting social interactions, see: Protesters.
I am very aware of the fall sense of security that is ever-present in our society. If you would also google it, you'll see that the countries that implemented masks have done the best job at slowing the spread. It's here, it's not going away, but there are ways to slow it to a crawl.
The guy that wrote that is an immunologist by the way. Here, to save you a click:
Masks - Wearing a mask while breathing, talking, yelling, coughing or sneezing catches respiratory droplets leaving your mouth and nose. Even with the most basic mask, virtually 100% of the large and medium-sized droplets are caught on the inside fabric surface. As the masks increase in quality, the amount of small respiratory droplets and droplet nuclei that get caught on the inside surface increases.
Quality includes:
Despite all the publications on mask use, there are no hard and fast numbers to provide. Each mask is different, and the way people wear masks differs. That is why it is so hard for scientists to tell you for certain what your mask should be made of and how effective each type of mask will be. Above all, we scientists like to be accurate, but that is not possible when there are so many confounding variables.
- How well it fits your face
- How much air passes through the fabric (versus up past your eyes/glasses)
- The type of fabrics included in the breathing area of the mask
At a minimum, it is believed a good mask will reduce 50% of emissions from the mask-wearer. Multi-layered mixed fabric masks approach filtering efficiencies as high as 90% (Ref).
I want to emphasize that there is not clear evidence to indicate that cloth masks will protect you from inhaling the smallest infected respiratory droplets (those droplet nuclei) from another person. The primary purpose of a cloth mask, when worn by everyone, is to serve as a control for source emissions. If we lower the respiratory droplets coming out of us, we can substantially lower the amount of virus put into the air, thereby lowering the risk to everyone.
