Papua New Guinea is still struggling to contain its first cholera outbreak in 50 years, which has affected 2,400 people since it began.
The water-borne bacterial disease was first reported in the country's north last year and since then more than 40 people have died across three provinces.
The World Health Organisation representative in PNG, Dr Eigil Sorensen, says another 400 people have been infected in the past month.
"It's slowly developing in the three provinces, which have been affected, Morobe, Madang and East Sepik. The total number is now about 2,400. And there're still a few cases in Lae town, where the outbreak started."
Eigil Sorensen says cholera is still spreading into new areas.
