My niece is in her third year of university in England. She looks to us for advice as her parents live abroad.
Her housemate has had a bad cough for the last couple of days, but otherwise feels fine. He has been continuing as normal, going to university, using their shared kitchen and bathrooms. He only briefly rinsed his hands with water in the kitchen but she clearly doesn't know how he washes in the bathroom.
DN and her other housemates asked him to self-isolate after this afternoon's advice. They have two bathrooms so suggested he have his own and asked him not to borrow their cutlery. The housemate has told the others to "stop being dramatic" because it's just a cough.
It likely is just a cough, but he can't know that. There haven't been any known cases in their university, and only one in the city. I don't know what to advise DN or if there's a way to protect other people in case he does have coronavirus.
(NC so I can send this thread to DN without revealing my usual name!
