I had an tip that I think is important. For those that are living with another, one at high risk and one healthy, still going out to work.
It will be very difficult cleaning commonly used items like landline handsets and the TV remote control especially cleaning those fiddly button areas. Why not buy a twin set remote phone pack then you can have one each. Make sure if the handsets are alike to mark one of them to identify them from one another like some tape or a sticker.
With the TV you can buy an additional learning remote (like a one4all) it is even possible to put an app on your mobile if you have a smart TV to control it. Then you don't have to share the remote.
