Well how fearful one should be I guess depends on how many active cases there are around, but that's not easy to find sometimes. But regardless if going to the grocery store is something that must be done, then wear a mask, limit trips, wash hands, and keep calm and carry on, because worry beyond that point doesn't do anything. People here wear masks though (it's the law) and social distance as well in the grocery, that hasn't changed. Stores are less packed mercifully though.
