The International Organisation of Migration, IOM, has confirmed that a dengue fever epidemic on Nauru has affected inmates in the detention centres there.
The camps which house asylum seekers denied entry into Australia are managed by the IOM.
Across the island at one stage up to 90 Nauruans were being admitted to hospital
each day, but this has now eased, with no new cases in the past fortnight.
The IOM says there were 17 suspected cases among the camp inmates and some of its staff were also infected.
The IOM's Canberra based spokesman, Denis Nihill says no one was so seriously affected they needed to be evacuated from the island.
