One case of meningococcal disease has been confirmed at the University of Otago, with an 18-year-old man admitted to Dunedin Hospital in a serious condition at the weekend.
St John said he was taken to hospital by ambulance at noon on Sunday.
A university spokeswoman said the man was a resident at Studholme College, and college staff were offering support to his family.
``Information about symptoms of the disease has been provided to the college and support offered to residents, including the offer of antibiotics for other students at the college,'' she said.
``Student Health and the university is closely monitoring this situation, and will provide further information as and if necessary.''
Southern District Health Board medical officer of health Dr Keith Reid said Public Health South was working closely with the university on the case.
The service was ``following up households and other contacts'' and offering advice and antibiotics where appropriate.
Meningococcal disease can potentially lead to either meningitis or blood poisoning. An Otago Polytechnic student died from meningococcal meningitis in 2016.
