A University of Otago student at Cumberland College in Dunedin has contracted measles after the visit of an infected Wellington student late last month.
Southern District Health Board medical officer of health Dr John Holmes said the student became ill on Wednesday last week - just within the 18-day incubation window from the Wellington visit.
He was unable to indicate how ill the student was.
The Wellington student with whom the Otago student had contact was admitted to hospital with the illness.
Dr Holmes was pleased with the effectiveness of containment measures introduced at Cumberland College when the risk became known.
"Public Health South is pleased that there has only been one secondary case."
The Otago student was isolated as soon as the illness was suspected, to limit further spread.
"All known close contacts [of the person] are understood to be immune. Regardless, there is a high level of vigilance at Cumberland College for any further cases," Dr Holmes said.
He reiterated a call for people to be vaccinated, and for those showing symptoms to stay home and call their doctor.
