What are neglected tropical diseases?

Neglected tropical diseases (NTDs) are a group of 21 illnesses that occur primarily in tropical and subtropical regions. They impact approximately 1.6 billion people in 149 countries around the world; affecting those who live in poverty and have limited access to adequate healthcare, clean water and sanitation facilities. NTDs cause illness, death, disability and disfigurement. They result in stigma, social exclusion, school absenteeism and lost productivity. Due to poor health and limited ability to spend on healthcare, people with NTDs often get caught in a cycle of poverty.

Global partnerships and unprecedented pharmaceutical donations have resulted in a great deal of progress toward the goals of control and elimination of NTDs. More than one billion people received treatment for NTDs each year for five consecutive years in a row between 2015-2019. 54 Countries have now eliminated at least one NTD since 2012. In 2024 alone, seven countries—Chad (human African trypanosomiasis), Jordan (leprosy), Brazil (lymphatic filariasis), Pakistan (trachoma), Timor-Leste (lymphatic filariasis), India (trachoma), and Viet Nam (trachoma) — were acknowledged by WHO for eliminating one neglected tropical disease (NTD), showcasing extraordinary global momentum against NTDs.
