Back to basic Health classes that we used to get in school, and I actually got a review of in college in 1992 ... However, the traditional students were in awe, because they had never heard this stuff before:
Herd Immunity - An idea applied to humans coming out of animal husbandry where you don't go in other's barns, keep them out of yours, and don't mix your livestock. This is a disease coming up from the south, so if you are in the midst of it you will need to take more precautions, but those of us at a distance need to stay within our own and take more precautions before mixing with you down there;
Personal Hygine - This has been touched on before, but wash your hands, and your whole body for that matter on a regular basis. Most pathogens are removed by 20 seconds of brisk washing with basic soap;
Proper Nutrition - Eat healthy and balanced meals to keep yourself well fueled to fight off disease and injury;
Regular Exercise - Regular exercise and activity puts our body in a mode of being able to fight off attacks. Something as basic as a thirty minute walk every other day has been shown to help, but a regular walk daily is better;
Sufficient Rest - Pace yourself, take a short break during the day, and get restful sleep every night. Rest is another one of those things that helps your immune system fight.
Add all this to basic food preparation rules and good housekeeping, and we should have nothing to worry about.
As a former Boy Scout I still live "Prepared." I keep mouse traps out, and that is how I find out I have mice (rather than waiting for them to invade and eat the food first), I fight bugs before they invade, I use "deet" as needed to prevent West Nile rather than fighting West Nile (by the way, I have had West Nile and it ain't fun), I use precautions concerning ticks to stop Lymes Disease before I get it ...
Basic life skills take the panic out of things like this. Don't ignore it, but it is just another pebble in the path of life! I know I am preaching to the choir, mostly, but most of the Country ain't in the choir.
