COVID protection for seniors who live alone?

If I were 91 or above, I would rather risk getting virus from my family, who knows what to do to lessen the danger of passing on the virus. My personal thoughts, once a week, perhaps person to person... rather than not seeing anyone.. Plus the physical distancing of 6 feet... I would risk it..
Although I am against someone 91 and older living alone. Had a neighbor whose wife passed away.. I would take over a cup of coffee and a bagel with cream cheese, knock on the door in the morning just to make sure I got a knock back... Yup,,it was concerning for me. Just wanted to make sure he had something to eat in the AM and he was okay... I always got a knock back until his sister finally came down and got him... FINALLY....

My dad is 88 years old and lives alone since my mom passed July 2018. I live about 80 miles from him. The little social life he was just starting to develop since my mom passed has all come to a halt with the coronavirus. Last I visited him was for two nights on 3/15 and 3/16. I call him every day and we talk for 30-45 minutes. He grocery shops with gloves but does not wipe down groceries.
I know he is lonely and would really like company. My husband and I are both very careful when shopping, practice social distancing and are working at home. The one minor in our house has not been anywhere since school let out 3/13/2020.
I would greatly appreciate input on this. I don't want to bring danger to my dad's safety but I also want to be company for him and I really do miss him. If i do visit i would want to stay one night due to the distance/travel.

My Mother is 95 and has been in the hospital since last Thursday night. I brought her home tonight. She has cellulitis which is redness and swelling in her legs and feet. She needed IV antibiotics since it was a bacterial infection. With this corona virus she doesn’t want anyone in the house and nursing homes aren’t letting any visitors in. Now isn’t the time for her to go to a nursing home. I don’t even know if they would take her because of the corona virus. So she lives alone. I bring her groceries and the mail and take out the garbage. I have to go to her house more often from now on to soak her feet. The doctor told me she needs her feet soaked every night. I brought her home and soaked her feet. Everything went well.
