Sunday afternoon the long distance trains in Germany had many Army and Navy personnel in uniform (which gets them free travel; may have been more in civvies paying their own way), including old reservists. We asked: they're preparing to institute mass isolation/quarantine, patrolling streets to "remind" people to stay at home. It isn't a question of "if" such measures will become necessary, it's just when will a country accept this, and how many extra deaths will be caused in that interval.
