Humanitarian action & health systems (MSF Scientific Days International 2022)

World Malaria Day is April 25th. The theme for 2023 is "Zero malaria: invest, innovate, implement" and the importance of reaching marginalized populations with the tools and strategies that are currently available. This collection highlights research on this theme, especially the latter two "i's": From research on Seasonal Chemoprophylaxis (SMC) and mass drug administration (MDA), to analyzing the reach of gene mutations (HRP2) in new environments, to other interventional research topics, these articles show how innovative approaches can be successfully implemented even in the most challenging settings to fight this global public health threat.

Complex humanitarian emergencies and other low-resource settings can be exceedingly difficult places to provide quality mental health (MH) care. Yet these environments also often have a high burden of mental health care needs. This collection presents a set of articles describing how MSF teams have adapted and evaluated ways of bringing clinically impactful MH care to neglected communities and patients—from forcibly displaced populations in northern Nigeria to Syrian refugees in Lebanon and typhoon survivors in the Philippines. It also highlights work on developing new tools for providing clinical supervision and for identifying those patients most in need of care in fragile settings, and on new approaches to delivering MH services during the Covid-19 pandemic.

"Clean hands, safe care" is the theme of this year's World Hand Hygiene Day. At MSF, we know that Hand Hygiene is the simplest and best way to prevent the transmission of infections in our facilities. This collection features some lessons learned about hand hygiene and infection, prevention, & control (IPC) in MSF projects, especially in resource-constrained environments in the Sahel, and in the era of COVID-19.
