The France, Canada, and Germany cases is why someone mentioned before that its not okay to pretend everything is 100% fine, that this will be 100% nothing. Yes, we survived the swine flu and so on. Yes, our immune systems are better than the Chinese. Yes, this has a chance to be a nothingburger but shit like this relies on human stupidity to fuck shit up for the worse.
AND this is a new strain with zero herd immunity. Even if this happens to be nothing, this will stay with us for possibly years, not helped by the antivaxers around.
Yet when I mention about that last detail to friends and such, I get handwaved with "reports are fearmongering", "we survived the swine flu, this can't be worse", "this is all a smokescreen by the government" and etc.
It is okay to be a bit worried and be prepared, but damn it, muffling it all wouldn't do any good. Calm down others from panicking too much, keep an watchful eye, have some ready materials; and if this happens to be nothing, laugh with each other at being 'too overreactional', but know that your materials and watchful demeanor is always ready for the next big thing.
