In nature weak die, strong survive and replicate. Species stay strong. In human world? Maybe humanity is a pipe dream?On the one hand, it's a dangerous precedent to set. If you can be detained for having one contagious disease, you can ostensibly be detained for having any contagious disease.
On the other hand, nobody wants people with XDR-TB running around infecting people left and right.
I'm not sure what the morally consistent solution is here.
