Great question, unfortunately I don’t think there is one right answer. My daughter has brain cancer so she is definitely part of the high risk population. Long story but at the end of March my sister in law was in town for one night and wanted to stay with us. I allowed it. She came to our house and washed hands and changed clothes on arrival. Now, when you have a child with stage 4 brain cancer you are also always factoring in quality of life and so that was a huge part of our decision (we were supposed to spend time with her and her family over spring break). I think there is no perfect way, but I would say if you are going to visit them consider staying with them, just minimize stops on your way and practice good hand washing, also, consider self quarantine for 14 days prior to your trip.
