What did I miss?
I would advise having hand sanitizer available at your home entrance and to remove shoes as you enter. Me, I have just gotten a UV lamp in my entry hall where I place packages and coats (turned on remotely for a minute after entry) I also change clothes when coming home and wash clothing more often. You may want to raise the air temp in your house and uv light room air filters (HEPA) but 20 of 7 is right avoid groups is perhaps #1.
