In the UK, people were found to be deliberately coughing on others, so it was made illegal [
source]. Yes, it really did happen :/. I guess the main reason "knowingly being infected and going out" hasn't been made illegal is at the time, most, if not all the tests were carried out for people already in hospitals and NHS workers. Now that the test is expanding to other key workers and individuals (very slowly) perhaps the law will change in this regard to be more explicit.
The WHO actually recommend you do not remove the mask [

I can understand why some governments have made the decision to make masks compulsory. I am certainly not in any position to criticise that.
TL: DR: I do think they have to do that.
However, I just feel that sometimes a lot of nonsense is being said both (1) to the general public or (2) by members of the public.
Regarding (1), i.e. what is being said to the public, I worry a lot about these home made masks and "advice how to make them". I don't really buy into any of it to be honest. At least not yet. The reason for this is because as far as I understand it, none of them have been tested properly. Even if a test or standard existed however, how can you guarantee people can make them properly to those standards? It leads to a situation where the masks have variable effectiveness, or perhaps none whatsoever. People are rightly mad about a test for the virus being only 75% accurate, but don't seem to have any problems with there being little or no(?) knowledge about how effective wearing home made masks are?!
Regarding (2), i.e. what members of the general public are saying, earlier in the thread we had an individual say something along the lines of "3M masks are best". Another individual was going to wear a mask just going for a walk, with no one around. Both comments were nonsense really. Some other individuals thought you could just wash these disposable masks and re-use them, or I think the implication was to wash home made ones. Thankfully someone posted an article saying you really need a specific set of conditions to clean the masks and it did not appear you can replicate those conditions at home, at least not yet. The WHO also say you cannot reuse single use (disposable) masks [
source].
On top of both (1) and (2), the science of how effective it is for the general public to be wearing masks to limit the spread of infection still isn't clear. I've seen two videos where some of the science was discussed. Both had flaws in basic terminology. I saw another article where the author(s) stated (t)he(y) would release simulation details on linkedin. Absolutely bizarre, something I've never come across before and sets the alarm bells ringing. Note that the WHO still doesn't advice the public to wear masks. One reason given was that there is a risk that "they can be contaminated by other people's coughs and sneezes, or when putting them on or removing them" [
source].
Having said all of that, I'm not adverse to the general public wearing masks and I certainly don't envy the policy makers having to make difficult decisions. I can understand the need to err on the side of caution and understand the decisions made. But I just think we need far better communication to the general public and ideally we also need people to wear masks which have been approved.
Interestingly though, we are seeing very little said about gloves. How do we know that wearing masks is more effective than wearing gloves (assuming social distancing/ isolation etc)? We know surfaces can be contaminated for a significant period of time but no one seems bothered by being infected via touching surfaces anymore. It is just all about masks. The discussion just seems a little haphazard. Wearing some PPE but not all. It leads to situations where we have individuals walking into a supermarket with full PPE.
I guess I am quite frustrated by everything. I want us to be led by clear science, but at the same time, I realize this isn't always possible and you need to be conservative. As I said this is extremely frustrating. I also don't want us to live in a society where wearing PPE becomes the norm. I would much rather we come up with engineering solutions to reduce pollution or better education to stay at home when ill etc. I do worry a lot that these sort of policies to wear masks will become the norm but I guess this worry isn't really important right now.
I agree, I think this is a good idea. Better for the UK to now have two meetings a week.
