The World Health Organization estimates that 410,000 people developed a drug-resistant tuberculosis infection (DR-TB) in 2022, only 40% of whom were diagnosed and started on treatment—and only 63% then cured. Given all these points of failure, innovation in preventing, diagnosing and treating DR-TB cannot come fast enough. To mark World TB Day (24 March 2024) the content collection linked below highlights recent work by MSF and collaborators to help change this grim picture. The TB-PRACTECAL and endTB studies delivered robust evidence for shorter, safer, more effective drug regimens that are already saving lives worldwide. Other studies explore new approaches to preventive treatment and simpler, quicker, accurate detection of TB and drug resistance—especially among difficult-to-diagnose populations such as children and people living with HIV. But to impact DR-TB globally these innovations must become widely accessible. This requires changes on many fronts, as described in an accompanying Collection (Expanding Access to Lifesaving New TB Tools).

Viral hepatitis is a major cause of disease and death globally. To mark World Hepatitis Day (July 28th) we present a selection of recent MSF research exploring how to effectively deploy powerful medical tools that could turn the tide on hepatitis C and E—but now reach only a tiny fraction of people who desperately need them, especially in low-resource and emergency settings. For hepatitis C, where groundbreaking new antiviral drugs can cure nearly all patients, MSF is piloting simplified, community-based models of care that offer rapid screening, diagnosis, and treatment under one roof. Some programs focus on the complex needs of highly vulnerable, hard-to-reach populations, such as people co-infected with HIV or TB or who inject drugs. Turning to prevention, an ongoing vaccination campaign against hepatitis E in an outbreak setting is showing early signs of short-term protection. Final results from this South Sudanese refugee camp, where poor sanitation and water quality regularly lead to outbreaks, should help plug a key evidence gap that—along with other barriers discussed in a commentary article—impedes widespread uptake of the vaccine.
