A tip for those who have to share homes with people who have Covid. In the rooms where they spend their time (their bedroom, bathroom etc.), put an ordinary fan in the window, blowing outwards. That will creative a slight negative pressure in the room, drawing house air into the room and out the window. It will help prevent Covid moving in the opposite direction, back into the house. For the same reason use the exhaust fan in the bathroom, if you have one, as well.
