Case tracking for ever ?? What is the idea behind this? Do it for the flue too ? It has always been done for AIDS, or Hepatitis C but they are a fraction as contagious as CoV-9 is.
Why not using simple medication in case somebody shines up with symptoms? How do you track 20x asymptotic cases that infect other 20x asymptotic cases and just 1 of 20 will be visible. You will loose all traces!! Case tracking is dead stupid nonsense as a general measure as it simply does not work as soon as 1 single asymptotic case occurs.
Countries like Japan, China will just face a never ending lock-down if they do not start to understand what really happens.
One to two years effort then there will be a vaccine. of cause if we get a good treatment the game changes. Also in sweden we have a immunity help it looks like this makes tracking easier.
FYI a bad flue season 1000 dies. now we are at 4000 and lands before 6000. if we could protect the one in elderly care we would have had 1000-1500 deaths. Possibly you have the same situation in Switzerland but hopefulle less problem in elderly care
