Neither of the ladies are in a bad condition in any way, they're just sticking to their beds and rooms. The upside of a McMansion in the midwest US is that every bedroom has its own bathroom, so isolation is pretty easy to do.
Us boys have no symptoms (yet) - my son and I. So we get the rest of the house. My hands are raw from all the handwashing and even moisturizing cream doesn't help anymore . Pretty busy times working a fulltime job from home, taking care of 2 patients, and running a household. Happy that it's almost weekend!
