Could I be liable if she gets Covid and spreads it to other residents? Thus far we've only gone for short drives and through drive-thru restaurants. I take every precaution to keep contact with people non-existent. I realize that my actions come with risks and are selfish.
Nevertheless, I don't think you're doing anything that would really expose her to anything as long as you keep her contact with others non-existent and you yourself have been tested and found to be negative.
Good luck!
P.S. If no one is holding the the governor of New York responsible for the 100's of nursing home deaths he allowed, I doubt if you have anything to worry about.
