Preparation and panic are not the same. Do not expect to rely on conveniences like deliveries, they are merely conveniences and can stop. It is very possible to run out access to necessities. I don't believe food itself will be in any significant shortage, but you might not get to it. If you fall sick, you'll need to self-isolate and not leave the house for several weeks. So you need to be ready to do so. Even if you remain healthy, access to supermarkets may have restrictions (see Italy today). While you can get food, you might need to line up for a few hours, increasing your exposure. Best to have a few weeks of food at home for when your area is in this stage. The alternative to preparation is to wait until you need to panic. Not recommended.
