Noma

Noma

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.

Adapting essential care programs to Covid-19 pandemic times

Adapting essential care programs to Covid-19 pandemic times
As the ongoing Covid-19 pandemic grips the world, one of its most devastating indirect effects is the disruption to medical services for preventing and treating other life-threatening diseases—especially in countries with already-fragile health systems. For MSF and other global health actors this means not only responding to Covid-19 directly but also assessing its impact on other essential care and then adapting programs so they can keep serving patients despite the enormous obstacles. In this Collection you will find a selection of published articles and conference content from this year’s MSF Scientific Days 2021 conference content, encompassing a range of approaches, settings and medical challenges—from malaria, TB and HIV/AIDS prevention and care to digital health promotion and sexual and reproductive health.

MSF Scientific Days Latin America 2024
View All Collections
On 3-4 May in Nairobi, Kenya, MSF gathered staff from our projects with experts from academia, clinical practice and the non-governmental sector to consider key issues in humanitarian paediatrics. These included: Vaccination and vaccine-preventable diseases: Amid post-Covid-19 global setbacks in child vaccination coverage, sessions spotlighted recent increases in vaccine-preventable disease outbreaks, potential new vaccination strategies and emergency responses, and MSF’s role in vaccine advocacy and catch-up campaigns. Nutrition: Talks covered the nexus of nutrition with other key conference topics, the latest malnutrition guidance and tools, and MSF’s priorities in nutritional care. Paediatric HIV: With half of all HIV-positive children globally not receiving antiretroviral therapy, presenters reviewed the latest paediatric testing/treatment recommendations and discussed barriers and potential solutions to implementation, nutritional challenges in children with HIV, and systems strengthening for preventing and monitoring paediatric HIV. Click below to read the abstracts. And stay tuned for more conference content, coming soon.

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.
