Getting anti-malaria drugs to people in remote areas of Papua New Guinea is the key problem facing the fight against the disease.
The World Health Organisation has warned that anti-malaria drugs will be in short supply throughout the western Pacific for several months because of increasing demand.
But WHO's PNG director, Dr Yves Renault, says the main problem i that country is getting the drugs to affected people in remote areas.
"We are not expecting a problem in the main centres, the problem is in remote areas, and little villages,.......the main part of the population in PNG lives in remote areas."
