If you are outside and can maintain 6+ feet (or whatever) you don;t need to wear a mask. If you are walking into a public building - Doesn't it kinda just make sense for now that you cover your face for your own good and those of others around you?
I think wearing a mask sucks and it is your ultimate choice to wear one, but FFS have some common sense and courtesy (and respect for others).
What in the current situation we are currently in has changed the science behind how PPE works? It didn't make sense before to wear anything other than a properly certified filtration respirator to protect you from a communicable disease, what has changed in order for you to say this?
Here's a hint: absolutely nothing has changed. You wearing a homemade mask to protect yourself from something as small as a virus is as effective as wearing a perforated condom and thinking it's safe sex because it might stop some of the HIV. The science hasn't changed.
I don't see anyone claiming that a cloth mask is intended to protect the wearer from contracting the virus. I think the idea behind it is to protect others if you're unknowingly a carrier.
There is absolutely ZERO evidence asymptomatic people can spread the disease. That was just a scare tactic put out from the onset. If so, it will be the only virus in history that has this feature. People who spread HIV, know they have HIV. The only thing a mask will help is if you have it with symptoms it MAY HELP keep from spreading it. But if you have it, just like the Flu, you should not go around people. I will leave this here for your reading enjoyment.
Effectiveness of masks against CoVid19
Quote:Can wearing a face mask protect you from the coronavirus (COVID-19)?
Face masks can play a role in preventing the infection, but that role is limited. A healthy individual in a normal situation does not need to wear a mask, as per CDC recommendations. A face mask is not the ideal solution for protection from the new coronavirus for the following reasons:
A surgical mask does not fit tightly over the nose and mouth.
It is not possible to prevent airborne virus infection.
It is difficult to keep a mask on for long periods of time.
When you touch the mask, you lose the protection and must replace the mask, and dispose of it safely.
A surgical face mask is highly recommended for people who have the coronavirus infection or have a high risk of exposure. It offers a certain amount of protection against infection from your own hands or droplets from the cough or sneeze of an infected person.
Now somebody ask me why the US was hit so hard from this. It is pretty obvious, but I can help with that too.

It's not about the virus as much as it is about the fluids that the virus 'rides' upon.
A surgical mask on 'me' doesn't reduce the amount of liquid released by your cough or sneeze.... that has an opportunity to infect me not only through my mouth and nose, but my eyes... and as a secondary contributor, to my hands and surfaces that I might touch. The virus can live on plastic and metal surfaces for many hours. It does demonstrably meaningfully reduce the amount of liquid released by the sneezer (which is the carrier for the virus) AND the distance that fluid travels.
The point of a mask in more open places (where social distancing is easy) is to augment/replace sneezing into a tissue as a means of limiting the spread... and no, not only do 'sick' people sneeze or cough or speak loud or spit a little when they speak. Here is a solid article on the whole issue.
https://theconversation.com/should-we-we...ion-135135 it even explains why 'six feet'. This number comes from this 'evidence'.
N95 masks (when worn properly which most people don't know how to do) DO help protect the wearer.
The CDC recognizes presymptomatic or asymptomatic transmission...
https://wwwnc.cdc.gov/eid/article/26/7/20-1595_article
They note epidemiological, virologic and modeling evidence of it... but more important, not everyone would recognize mild symptoms and seek medical attention or self-quarantine... so you could absolutely be symptomatic, but perhaps a mild case, or you're just not aware of what the symptoms are... or which ones you have.
Now, if you want to argue the statistics, that's fine... Yes, someone in flu blown and serious infection has 'more' of the virus than someone who doesn't. We're now arguing over the definition of 'a lot', which seems rather pointless as honest people can disagree not only on the definition of 'a lot', but as to what steps are 'reasonable' in response to 'a lot'.... but still... if I work in healthcare and someone with the disease sneezes and it falls to my shoes, and I use my hands to remove my shoes and then touch the credit card machine at the cafeteria, you could get it from someone with no infection whatsoever.
N95's are uncomfortable.... and absolutely restrict air flow. That's their job. Bandanas or surgical masks don't need to be uncomfortable. Yes, they can be uncomfortable at times and of course, you can get too hot breathing behind one and need to 'air it out' to avoid sweating, but still... sweat is a more controlled release than a cough or sneeze... and if you're putting your mask on and off at reasonable intervals, you can catch the overwhelming majority of unintentional 'spray' while not risking sweating through your mask and defeating (somewhat) the purpose.
