Hundreds of university students in Manchester have been told to isolate after 127 tested positive for coronavirus.
Some 1,700 students at the Birley campus and Cambridge Halls at Manchester Metropolitan University have been told to stay in their rooms for 14 days, even if they have no symptoms.
It comes after students in Scotland were told to avoid pubs after coronavirus outbreaks forced hundreds into isolation at universities including Glasgow and Edinburgh Napier.
Across the UK, at least 32 universities have confirmed cases, while one other has suspected cases.
Michael Melia, a student at Manchester Metropolitan University, said there was not a "happy mood" in his flat.
"It was very sudden, there was no real warning," he said. "The flat are all the outgoing sort so they're taking it hard."
More than 510 cases have been identified among students and staff since universities reopened, according to data collected by Sky News up to 25 September.
In Manchester, the University and College Union said the incident was "the latest catastrophe in a week where wholly predictable - and predicted - COVID-19 outbreaks have caused havoc on campuses across the UK".
General secretary Jo Grady said: "We warned last month of the problems with moving thousands of students across the country and the time has come for urgent action from ministers and universities to protect staff and students.
"Manchester Metropolitan University shifting teaching online only for foundation and first-year students exposes the total absurdity of the current position of trying to continue with blended learning."
