OXFORD: About 130 cases of a gastrointestinal illness have been reported at Mansfield College since its ball was held on Saturday, February 2.
The Health Protection Agency has been working with Oxford City Council and Oxford University to investigate the illness - which causes vomiting and diarrhoea - but it is still not known whether it is food or virus related.
HPA spokesman Claudette Malone said investigations were still on-going.
