While I’m not joking any protests anytime soon I do feel that liberty is important and there are a few interesting contradictions worth pointing out in your post..
Good points and certainly valid. However, the right of one person ends where the rights of the next person begins. Nobody has the right to infect others only because they are too lazy to take precautions.
You will agree that someone driving on the wrong side of a highway (i.e. against the legally prescribed direction) endangers other drivers and that the right to his individuality certaily doesn't cover the right of driving in the opposite lane.
Not wearing a mask and not keping distance to others is essentially the same. Like traffic rules, these rules were set to protect the whole society. Endangering others' lives goes lightyears beyond the personal rights guaranteed by the constitution. If someone is too egocentrical to consider the health and the very lives of his fellows and to see that these laws are there for protection (his own included!), I think the victims of his misbehaviour have a right to call him mentally - or at the very least socially - deficient.
I assume by Test #1 you meant the antibody test.
No, I mean a test for the active virus.
Over here, we do no antibody tests because those tests are not yet far enough developed to be of any use: they have an extremely high rate of false results and that might be potentially dangerous.
What if someone in a high risk group gets the false result that he's immune? He'll expose himself carelessly, get infected and might die. If a doctor or nurse gets wrongly tested immune, they might suffer the same fate and as they all are atm extremely exhausted and therefore have a badly working immune system, their chance of survival is reduced.
Our experts consider these risks too high and will wait till properly working tests are available.
Until then, in Germany and afaik of the rest of Europe everyone who was infected has to undergo 2 tests for the active virus. If in both tests no surviving virus can be detected, the person is assumed to be recovered.
Whether surviving an infection will lead to a long-term immunity has yet to be found out. We play it safe and assume they won't be immune much longer than a few weeks.
So when my SIL goes back to work, she'll still have to wear full protection gear to protect herself from a new infection and to protect her patients from her transfering a virus to them.
