Neglected tropical diseases (NTDs) impact nearly 1.7 billion people each year, causing serious illness or lifelong disability among many—often leading to stigma and exclusion—and killing an estimated 200,000. The vast majority of sufferers live in the world’s poorest countries.

The World Health Organization’s NTD roadmap 2021-2030 aims to address 20 tropical diseases through prevention, control, elimination, and/or eradication. But despite some progress, reaching all its targets will take better, far more accessible diagnostics and treatments along with more robust strategies, political commitment and resources.

To mark World NTD Day, this collection spotlights work by MSF and collaborators on improving approaches to snakebite envenoming, kala azar and noma. One study presents an innovative artificial intelligence-based snakebite diagnostic tool, while others evaluate shorter, less toxic drug regimens or different models of care. Several commentaries advocate for national/regional strategies adapted to contexts ranging from remote villages to active conflict zones. Another crucial factor is the climate crisis, which is intensifying the transmission and geographic spread of many NTDs.

MSF Scientific Days in Latin America 2024 focused on two thematic areas:

Climate Emergency in the Americas: What Are We Seeing as a Medical Humanitarian Organization and How Are We Responding?

• MSF has long responded to health crises aggravated by the climate emergency —such as disease outbreaks, food insecurity, and displacement—and these events are intensifying in severity and frequency. This session presented examples of how MSF is adapting to address climate-related emergencies in the region, and explored strategies for future humanitarian action.

Mental Health and Psychosocial Support Interventions in Violence, Migration, and Indigenous Health Projects

• This session explored the complexities of providing mental health and psychosocial support (MHPSS) in some of the region’s most challenging settings. It focused on interventions in areas affected by violence, the mental health impact on migrants, and the unique needs of indigenous populations. The discussion highlighted innovative strategies, culturally sensitive approaches, and the importance of integrating MHPSS into healthcare projects in these complex settings.
