Two tourists visiting Niue have been taken to hospital with dengue fever.
More than 100 people, or about eight percent of the population, are believed to be suffering from the fever and visitors are being warned to use insect repellent during early morning and evening.
Dengue, which does not often occur on Niue, has been afflicting the island since February.
It was originally confined to a small area of Niue's main village but has now spread y throughout the island.
One local man recently died from a serious form of the virus.
