Almost 3000 people in Papua New Guinea have been infected with cholera since an outbreak began eight months ago.
The country's first cholera outbreak in 50 years is affecting three adjoining northern provinces - Madang, Morobe and East Sepik, Radio New Zealand International reports. About 2,900 are recorded as having the disease.
The World Health Organisation's representative in PNG, Eigil Sorensen, says 500 people contracted cholera in the second half of March, but the infection rate has since eased.
Dr Sorensen says there were about 10 new infections over the past two weeks.
