I think it depends on where you live and how widespread the epidemic is in your area. I have a lot of friends who are young and healthy but still doing their best to stay home and avoid spreading the virus so that it doesn't impact the elderly and people with chronic health conditions who are vulnerable to a serious case of COVID-19. While this coronavirus does not generally turn out to be a severe case in healthy people, there are some exceptions so I think caution is still warranted.

For grocery shopping, our local authorities are recommending that you use the pre-order option that some stores are now offering, or at minimum go to the store during off hours when there are fewer people. Our local Kroeger stores offer the ability to pre-order and pick up at the curb for only $5. They even put it in your car for you. Target and Walmart offer similar services, and I believe other chains do as well. These services existed before the epidemic but are certainly handy now. You might check and see if your local stores do something similar, and if not, at least go to the store during non-peak hours. Sanitize your cart, and wash your hands immediately upon returning home.

Stay well. I'm sure we will get through this but it's certainly crazy in the meantime.
