Protecting family from Chemo medication

Thank you @Afraser for your response. Lucky we have two toilets. Use of separate toilets and  rooms, cleaning and good hygiene ( wearing masks maybe)  would be a way to go. I think I will manage as it is only me and my husband at home, but our son comes often to visit. Having small children would probably be more challenging to manage. I will use this as an excuse for stopping the visits from friends  ;)
