Annually, tropical diseases are a major cause of mortality; for instance, in 2019, neglected tropical diseases (NTDs) caused 150,000 deaths and 19 million DALYs, with sub-Saharan Africa bearing over half the burden and the other concentrations in Asia and South America. Their impact, though significant, is lower than ischemic heart disease and respiratory infections. The World Health Organization is critical in combating these tropical diseases through surveillance, information campaigns and health promotion. Through international collaborations and initiatives, tropical diseases have been relatively mitigated; for example, global initiatives eradicated smallpox (1980), cut polio cases by 99% (1988–2022), and reduced Guinea worm cases from 3.5 million (1986) to 14 (2023), while NTD prevalence dropped significantly from 1990 to 2020.
