My oldest daughter works is a social worker at our local hospital intake. This means I get a periodic lecture about how to prevent the Red China flu. Based on what she says, social distancing is the easy part of prevention. Transmission from contaminated surfaces is much more difficult to deal with.
She, and her husband get home from work, shopping, or whatever they do in the outside world. They leave their shoes outside of the house. They get inside and strip off their clothes and put them in the washer and take a shower. Then they get into their safe and clean clothes. Then they take an alcohol soaked rag and clean the doorknobs and other things they touched upon entrance.
Everything coming into the house is disinfected or put out in the garage for at least three days. That means, the cap or hat, belt, wallet, credit cards, money, car keys, etc are all sanitized with an alcohol wipe.
In addition to all of this, they pay attention to not touching their faces all day when out of the house, as well as social distancing and wearing a mask in critical locations.
I am sorta lazy and retired so I stay home and use carb cleaner for disinfecting things. Otherwise I follow their protocol.
Someone told me this a long time ago "You are crazy or you do not fully understand the situation." The more I learn about this virus the more wary I am.
