This has been our strategy. The biggest problems have been my wife being required to come in to work and our teenage daughter wanting to go to places like Starbucks every day. It's the drivethru, but we treat that coffee cup like it's contaminated. She has to transfer the coffee to a new cup when she comes in, toss out the old cup, then wash hands. Not perfect, but the best we can do. We have told her the almost daily trips are not continuing.
Other than that and maybe 1 trip to a grocery store a week (just one of us goes) it's been isolation. Go out for exercise when the weather is good, but we don't come near anyone and don't touch anything.
When my wife comes home we do a decontamination drill. Shoes stay in the garage. Clothes go straight to the washing machine. She takes a shower. I follow behind her wiping down the door handles.
