Of course we should be closing schools, kids are super spreaders. We should also be cancelling all large gatherings, halting all travel, and issuing hazmat suits on prescription. Hospitals are full of sick and old people let's close them too, the nurses and doctors will be at home looking after their kids anyway.
Or we could all relax and trust people who do emergency planning as their actual job. We're probably all going to catch this thing, some people are going to die. It's sad but in all honesty we can't continue hoping everyone will live indefinitely. Throughout history there have been large scale outbreaks which have brought the population under control somewhat.
