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.

Globally, the number of older people is rapidly increasing, with those aged 60+ expected to more than double by 2050—yet in humanitarian crises, they remain one of the most neglected groups. Older adults often face higher risks due to chronic illnesses, mobility issues, and limited access to appropriate care, especially in low-resource or emergency settings. Despite these needs, humanitarian responses rarely prioritize them, and data on their health and mortality are often lacking.

This collection reflects MSF’s ongoing examination of its own data and practices to identify pathways toward more age-inclusive services in humanitarian crises. It includes analysis of data from MSF-supported mental health services, inpatient departments, and sexual violence services, and further offers several calls to action and reflections on why older people remain overlooked in humanitarian crises. However, MSF also acknowledges major challenges remain, including inadequate age-inclusive services, data gaps, and the need for more geriatric expertise.
