Common sense should prevail. Of course, the jokehovian witlesses will wait on joke-hova (who brought this here in the first place). I would avoid boasting sessions and field circus altogether, regardless of whether the virus is here or not. And only partially to avoid getting or spreading it--to avoid adding more energy for joke-hova to keep it going or bring communism out of it, or to create the next, even worse disease and panic.
It makes common sense to prepare for shortages. Stores will empty out of basic commodities quickly when the disease comes to your town, whether or not it is serious. These shortages, and the panic that results, will kill more than the virus itself. And, since China is still disrupted, I expect shortages due to supplies not making it at all. Get basic food and supplies now, while you still can. Many cleaning supplies come from China, in part or total, and will be in short supply whether or not the virus gets in your area. Getting a few extra cans of soup, vegetables and fruit, and prepared meals is a good idea, along with a few extra boxes of pasta, rice, dried legumes, and different grains. Powdered milk, condiments, and spices will also help. I don't think we will get widespread blackouts and water outages directly due to the panic, but the commodities will run out quickly.
As for supplements, get things that support the immune system now while you still can. If you live where they are legal, I recommend getting vitamins C and D3. If you take nothing (or only a multi), start with 500 mg of vitamin C twice a day, and at least 2,000 units vitamin D3 (and up to 5,000 units a day). Herbs are a help--astragalus, echinacia, ginger root, oregano oil, elderberry syrup or juice, antioxidants, and the like may improve your chances of getting a mild case or none at all instead of a serious case. Magnesium (at least 400 mg per day) and boron (at least 6 mg per day) will help prevent problems with small amounts of MSG added or naturally present in processed food (plus you are most likely deficient in both). Do your own research on this, and add whatever you see fit to this. And, throw those cancer sticks away if you smoke--you will not get disfellowshipped, but they could make whatever virus you get worse.
And no, do NOT wait on joke-hova or the Filthful and Disgraceful Slavebugger. If you are in the USA, Australia, New Zealand, Canada, or parts of Europe not yet affected, NOW is the time to prepare. If you wait on joke-hova or the Filthful and Disgraceful Slavebugger, it will be too late and the food will be all gone. (Along with the supplements, which may not even be available in parts of the world thanks to Codex Alimentarius).
