This is my biggest concern. I don’t even think this is “the big one”
This isn't some society-collapsing event, but it does require containment so our medical infrastructure doesn't get overwhelmed. If you get it, you'll most likely live, even without medical attention.
That being said, we do need to treat it seriously. It isn't just a dress rehearsal for something worse, but it is telling in how people react. I'm worried about what will happen if something worse comes along.
What I have learned, however, is that my general strategy is always keeping 1-2 months of basic essentials on hand is a good idea, and that I need to be more vigilant about it because people overreact.
