A friend's 20 year old daughter is returning from holiday in Portugal on Sunday. Daughter now needs to quarantine. The govt rules state that you should not have visitors. Friend's question is - if daughter stays in her room for 14 days, only leaving to use the bathroom (no one else will use this bathroom), can the family still have visitors downstairs? Friend thinks they can, her husband says they can't. Personally I wouldn't but she'd welcome views...
