Power Line links to an analysis of the Diamond Princess "plague ship" experience posted at Watts Up With That. Imagine, a bunch of senior citizens trapped on a cruise ship in Asia with Covid-19; it sounds like a disaster movie scenario.
What actually happened is that 83% of the passengers never caught it at all, and of those who did get it, almost half were asymptomatic - translation: they never felt ill. Nearly three-quarters of those over 80 - the most at-risk group - did not catch Covid-19. There goes your disaster movie script, the reality isn't scary enough.
