Pacific Island countries are on track to eliminate filariasis from the region in the next few years says the World Health Organisation.
In mid October the UN agency announced that Lymphatic Filariasis had been eliminated in the Cook Islands, Niue and Vanuatu.
The mosquito born illness which can develop into elephantiasis is endemic to 16 Pacific countries.
The WHO's Pacific medical officer for neglected tropical diseases says the region's 13 remaining nations with the debillitating illness are due to eliminate it by 2020.
Dr Padmasiri Eswara Aratchige says the Pacific programme began in 1999.
He spoke with Dominic Godfrey about mapping the presence of the disease and subsequent mass drug administrations in the path to elimination.
