The number of people who have tested positive for Covid-19 at the University of Sheffield has risen to nearly 500.
The University of Sheffield's updated figures showed 307 reported cases up to Friday, but by Monday it had jumped to 479, including three more staff.
The university started sharing its figures on 28 September.
Meanwhile the neighbouring Sheffield Hallam University said it has recorded 373 cases in the last two weeks.
Reported cases in the whole of Sheffield have increased from 91.8 per 100,000 people to 233.1.
There were 1,363 new cases recorded in the week to 1 October, according to Public Health England data published on Sunday.
The University of Sheffield said campus teaching is currently at about 20%, with the rest delivered digitally to reduce footfall and infection risk.
Staff and students must wear face coverings, unless medically exempt, and class sizes are restricted to 15 students.

Sheffield Hallam University has increased the proportion of online teaching for the next two weeks as a precautionary measure in light of increased local and national transmission.
A spokesperson said: "We are working closely with our partner accommodation providers to keep students safe, whilst providing a range of support for those self-isolating, including food packages, wellbeing support and access to medicine for those that need it."
Sheffield is one of the locations named as an "area of concern" by the government, with an infection rate of 233.1 per 100,000 people as of 4 October.
Director of Public Health, Greg Fell, said a local lockdown is "probably not that far off" and he thought it would be at the most within the next month.
