Noma, also known as cancrum oris, is a rapidly progressing life-threatening infection that affects the mouth and face. Noma is preventable and easy to treat if addressed in the early reversible stages, but most often deadly if untreated. The disease most commonly affects children who are chronically malnourished or whose immune systems are otherwise compromised. Noma affects an estimated 140,000 children annually. Noma was added to the WHO's list of Neglected Tropical Diseases in 2023.

MSF is working to discover more about noma. This collection highlights MSF's mixed methods research on treatment outcomes, burden of disease, attitudes towards the disease and other aspects of noma.

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.
