My daughter who is a bit of a germaphobe, has always wiped down her shopping when she unpacks it. I never taught her this (I have never done it). She continues to do it post-vaccine. She commented last year on how people were saying it was so much extra work now to wipe down everything they bring into the house, but not for her as she has always done this.
I remember an early interview with Fauci where they asked him what precautions his family was taking. He said they were leaving the mail or wiping it down, but still having a person come in to clean the house. Seemed then, and I think it is proven now. The bigger risk is the housecleaner, not delivered packages and mail.
