I take these as examples of how quickly things can go wrong if they go wrong. People seem to overconfidently brush this off as isolated incidents because religion is stupid and we're not all in a cruise ship. It could also serve as an example of how bad things can get if one person goes unidentified and happens to go to a crowded place. Like a teacher, or clerk, or waiter. Just this past week a coworker returned from Beijing, and there was nothing in place at Frankfurt airport. No questions, no flyer asking you to wash your hands frequently, no phone number you're supposed to call if you feel sick... It's left to the common sense of the individual, which I don't trust everyone to have.
