Dd is staying in halls. One of the girls in her flat had a cough and a fever on Monday. She didn't tell the others straight away but as soon as they found out they began self-isolating on Tuesday. All of the others went home within a day or two leaving dd alone. The only people who are able to bring dd home are in at risk groups so they were going to wait until Wednesday to go and collect her. Except that today the original girl with symptoms has suddenly moved back in. Not only that but she has brought her bf and friend with her and they're all just hanging out in the kitchen as if there's no problem. I'm desperate to get dd home but not at risk to other family members. What would you do?
