The neglected tropical disease non-governmental development organisation network (NNN) is a global forum for non-governmental development organisations (NGDOs) working to control or eliminate neglected tropical diseases (NTDs) including leprosy, lymphatic filariasis (LF), onchocerciasis, schistosomiasis (SCH), soil-transmitted helminthiasis (STH) and trachoma.
Each of these diseases has elimination as a target where feasible and each receives generous donations of medicines from the pharmaceutical industry.
