It's extremely unlikely for an individual, perhaps, and I'm honestly not particularly afraid for my life. (If anything, I'm worried about my convenience, whether I get sick or just people in my area.) However in aggregate if we act in a conscientious manner, we can slow or stop the spread in our own areas, and/or head off a run on supplies by doing some shopping early. I agree we need to be measured. I'm not changing my behavior much yet since community spread hasn't hit my area. Once it does I might try to reduce my time in public. Even now I may consider staying away from conferences that bring travelers, etc.
