a household member arrived from abroad, they do self isolate from us in the house?

[Tomatoesneedtoripen]

and just how?
or just clean the bathroom after their use?

Is it a country on the quarantine list?

yes

We had the space that our visitors had their own bathroom and we put a mini kitchen in an alcove (kettle, toaster, microwave) so they could properly self isolate. Otherwise I think you would be cleaning and wearing masks all the time!

There's advice on gov.uk on how to self isolate from other people in the same dwelling.

Obviously how easy this is depends on how big your house is and how many bathrooms. You can only do your best with what's available and limit close contact and touching of the same items to reduce the risk.

thanks all

My nephew came home from uni with it (very mild symptoms) in March. He stayed in his room, they left his meals outside his bedroom door and only he used the family bathroom. No one else in the house picked it up.

thanks @Alexandernevermind

dd also came from uni in March

I am less worried now than I was then

oh, but he had symptoms?
that is good that no one caught it @Alexandernevermind
