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.

Unsafe abortion is a leading cause of maternal death, and the only one that is completely preventable. Yet over 30 million unsafe abortions occur each year, leading to at least 28,000 deaths and millions of serious complications—nearly all in low- and middle-income countries. MSF teams see these tragic consequences first-hand, treating thousands of patients every year with severe, potentially life-threatening effects from unsafe abortion. So in 2016 we launched a program to systematically implement safe abortion care (SAC), starting with ten pilot sites and then applying the lessons learned to scale up at projects across the globe. This Collection presents highlights of these efforts. Since our first publication on the need to provide SAC as a way of reducing maternal death and injury, several studies assessed the role of unsafe abortion in driving this suffering in specific contexts. Others described internal obstacles to providing SAC, operational solutions developed, and outcomes achieved. And we advocated for shifting towards community-led and self-managed SAC, particularly given new obstacles that emerged 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.
