Until scientists/medical experts decide how the virus is being passed between people (which they're still arguing about), it's impossible to even guess at when/how restrictions will start to be lifted.
If it's by touching surfaces, that will lead to different scenarios as to if it's passed by touching hands, which in turn leads to different scenarios if it's passed by hugging/kissing, which is again different to whether it's passed by coughs/sneezes, or of course, whether it's so prevalent it passes by all of those.
Also, it would be good if the scientists/medical experts decided the highest risk groups - is it men/women, is it young/old, is it pre-existing conditions and if so, which ones.
We really need to know the facts before anyone can even start to think how we did ourselves out of this. If, say, it's caused mostly by blokes shaking hands and those with diabetes are at greatest risk, then the action plan to stop it spreading is very different as to whether it's being passed by women kissing eachother on the cheeks, or by random strangers touching the same handrails on buses.
