uk lockdowns are in response to hospitalisations. not due to asymptomatic infections.
the UK lockdowns are more about the view that people are not following the current guideance at advisory level eg 'if you can work from home do so' and so if people are not bothering to stay home if they can.. eventually they will be made to..
Well of course they are for deaths/hospitalizations. Even when the UK was top 5 in deaths per capita, they didn't necessarily have lockdowns in place. Even top doctors in the U.S. say asymptomatic people aren't the ones that act as super spreaders (which also makes me wonder why it's so important to mask up if you're asymptomatic, but that's another discussion).
there is a difference between asymptomatic and pre-symptomatic
they actually done a study back in march and first thought that it was ~50% asymptomatic. however further analysis showed that the study only checked if the person had symptoms at the time of testing. and not following up with them over the following week to see if they later develops symptoms. so in the new study which did include follow ups. only 17% were asymptomatic and the other 32% did develop symptoms later but were just being tested too soon.
so here is the point. in the first 5-12 days you might be incubating the virus and then aspirating it out before your symptoms begin in 82% of cases. so its not about only wear a mask at day 5-12 when you start getting symptoms
its instead wear a mask before you have a chance to get infected. hense never getting it. or also protect those around you if you did get infected but dont realise it yet.
those with symptoms should stay home. if they are still mingling in public then they are irresponsible.
masks are for prevention of getting it/passing it on without knowing, as is social distancing. self isolation/staying home is about preventing you passing it on when you know u got it, or suspected of having it due to being a close contact.
you could run a real life scenario
pick 5 people. and tell them if they do come into close contact with someone either by accident or on purpose to spray paint a colour on someones back. and advise then to try not to come into contact. but if they o to then tell that person the same advice.
then give those 5 people a different colour spraycan to use
after a month. you can then look at a populations back and count how many of which colour. and then know which group are more idiots and ignorant. just by counting their backs
it does not mean that the colour is more dangerous. it just means the people that come into contact with each other in that cluster-colour are more ignorantly dangerous
I'm curious, what is your solution if people don't follow lockdown regulations? Jail them? Fine them?
most countries already have provisions to fine people. then if you dont pay the fine and keeps ignoring the rules their fine increases.. if there is no intent to pay then you could be locked up
other ppossibilities like those who are supposed to be self isolating get a 'welfare' call 2 random times a day. and if they dont answer their home phone. they obviously breached the rules by not being home to answer.
thus a fine is posted out to them.
obviously if they do answer. they get the benefit of speaking to someone and also the welfare service should be to check how they feeling and also organise any 'foodbank' provisions if their kitchen pantry is empty
ensuring they have everything they need to not venture out.
(asian countries done this with physical checks at the door each day. but id concede a phone call can be just as effective without being too laborious/invasive of personal lives)
as for not wearing a mask in close proximity locations (train/bus/grocery stores) have lots of masks spare to just hand them out to people. and if people then avoid even that. they have no excuses left. and told to leave the location. if they protest and refuse to leave. then call the cops.
i dont believe in just calling the cops if you see someone without a mask. i beleive in giving them a chance via giving them a mask. then give them no other excuses or leave location. and if then they refuse. then call the cops as thats then trespassing.
things like the london train station scenario. should have had more station employees managing how many people are allowed into the train station in the first place. heck they should have for months had extra carriages per train to allow people to have some form of personal space between them and the next passenger
