New tools and approaches to drug-resistant TB

New tools and approaches to drug-resistant TB

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).

World NTD Day

World NTD Day

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.

World Hepatitis Day 2022

World Hepatitis Day 2022
Each year hundreds of millions of people suffer from chronic or acute liver disease caused by hepatitis viruses, and over one million die. To mark World Hepatitis Day (July 28th) we bring you a selection of MSF research exploring how to better prevent, identify and treat hepatitis infection in lower-income countries and emergency contexts where the burden is heaviest. For example, in a South Sudanese camp for displaced people—a type of setting where poor sanitation and water quality regularly lead to hepatitis E outbreaks—MSF and the Ministry of Health (MoH) are conducting the world’s first reactive vaccination campaign against this disease, and evaluating the process and outcomes. In Cambodia, MSF and MoH collaborators found that a simplified community-based model of care for hepatitis C was safe and highly effective in diagnosing patients and in curing them with new antiviral drugs. It was also cost-effective, according to studies in several countries and patient populations. And these new drugs were safe and effective even in patients also being treated for drug-resistant tuberculosis.
Mini-Lab—MSF's simplified bacteriology laboratory for low-resource settings

Mini-Lab—MSF's simplified bacteriology laboratory for low-resource settings
Resistance to antibiotics is a growing public health crisis, especially in countries with fragile health systems and in regions at war. One key limitation in most of these settings is a lack of clinical bacteriology laboratory capacity, which leaves medical providers without ways to accurately diagnose patient infections and to tailor antibiotic treatment accordingly. To help fill this critical gap, MSF and partners have developed the Mini-Lab—a small-scale, standalone lab that is easy to transport, set up and operate by staff after only a short training. Its six modules are stocked with everything needed to diagnose common bloodstream and urinary tract infections and to perform antibiotic sensitivity testing using methods adapted to extremely hot climates and remote settings. With Mini-Lab now being rolled out to selected MSF projects, here we highlight the background to its development and some of the research behind the bacteriological tests it incorporates.
