I have been stocking up on things, not so much to avoid the virus but to avoid the panic and shortages that come along with it. Reasonable quantities of food items--bought piecemeal (I am aiming for 6-8 weeks supply, given that this is how long the disruption is most likely to last in some form). Also get cleaning and paper supplies. I think it is stupid to buy 10,000 cases of paper towels for this, but go a bit heavier than usual.
What kind of food? I suggest a variety of non-perishable items. Powdered milk, rice and grains, legumes (peas and lentils are also legumes), canned fruits and vegetables, dried instant potatoes, and so on are good to have on hand. I also have a variety of condiments (mustard, spices, and different types of pepper sauces) for variety, since it is boring to just eat plain rice and legumes all the time. I even have on hand crackers, cookies, tortilla bread, peanut butter, jams, and cookies since it is nice to have treats on hand for this. This is not an austerity drill--I will save that for once World War III comes and genuine shortages come from that, not for this.
Supplements? Since I will be exposed to more glutamate than usual from this, I intend to keep taking magnesium and boron. This is to throttle the calcium that otherwise would be pumped into my brain and nervous system by the glutamate (and because most of us are deficient in these minerals). I got oregano oil and echinacea, which worked nicely for a dental abscess in lieu of antibiotics. I also have elderberry syrup, which is to help my immune system. Left to get is the ginger extract. This will hopefully throttle the virus if I get it, giving my immune system a chance to knock it out before it creates major problems.
I got these all from a high rated supermarket. So far, there are no genuine shortages, although that could abruptly change. I have been treating Walmart as an infection hotbed for all sorts of infections (including spiritual infection) since they disappointed me on Christmas items in 2009. (And they are among the worst for quality, sourcing most items from China where the supply disruption is worst.) In addition, this dump will be the first place to have acute shortages, as well as fights that could be worse than the virus.
In the USA, Publix and Raleys are the top rated supermarkets. If you are lucky to live in the Northeast, you might have access to Wegmans (to me, that is like going to Italy without spending all the money or risking the infections running through that country). Hannaford's is another good supermarket. They are more likely to continue having basic staple food items and fewer, less serious fights than Walmart.
