I kind of am. We just got a new-to-us fridge (my mom actually bought it 2 years ago, when my brother moved back in with her, and then decided it was really too big for one person after he died and replaced it with a counter-depth model) and there was much uncertainty over the delivery date as we waited on her new one to be delivered and my husband to have a day off to install the water line for it. So I got into the rather bad habit of just buying a day or two's worth of meals at a time to avoid having a full fridge when the new one came. The grocery is less than a mile down the road, so it really isn't any big inconvenience to shop as needed, but we couldn't get through more than 4 or 5 days with what's in the house and some of those days might get a bit weird as we dipped into pantry stuff that doesn't necessarily go together. The warnings about the virus have prompted me to do a real shopping trip, to the bigger/cheaper chain grocery 15 miles up the road, so if someone in our household does get sick we wouldn't have to worry about running out of food or TP.
But I don't think we're likely to see the kinds of containment measures here that are happening in other parts of the world, even if a significant number of cases emerge. In fact, I doubt we'll even really know how widespread it is, considering the financial disincentives for sick people to go to the doctor for diagnosis. Crashing the economy in hopes of containing a virus that has already defied so many containment efforts would be politically disastrous. We just don't have the safety nets to justify that kind of action - imagine the foreclosures, the utility shut-offs, the defaulted debts if we tried shutting down schools and workplaces for weeks or months in a paycheck-to-paycheck nation! - so I expect we'll see far more moderate measures (platitudes about handwashing and staying home when sick) combined with a message that downplays the disease risk.
