A cholera outbreak in Papua New Guinea's Morobe, Madang and East Sepik provinces is continuing to affect dozens of people.
The World Health Organisation has not received updated figures, but about 1,400 people were confirmed to suffer from the illness in total in late December.
The WHO's epidemiologist Alex Rosewell says most districts in Madang are now reporting clinical cases, some villages in small numbers only.
Mr Rosewell says the areas requiring close attention are in the Murik lakes in East Sepik and Markham District in Morobe.
He says health officials and aid workers have been visiting the areas for infection control and to provide access to safe water.
