Risk stratification of childhood infection using host markers of immune and endothelial activation in Asia (Spot Sepsis): a multi-country, prospective, cohort study
Posted 24/09/2025. WHO danger signs often misclassify febrile children in resource-limited settings. In the first community-based study across seven Asian sites, Arjun Chandna and colleagues show host-response biomarkers, especially sTREM-1, outperform traditional tools for predicting severe illness. These findings highlight the potential for biomarker-based triage tools to transform childhood infection care.
A just war on bugs? Ethical differences between antimalarial resistance and antibacterial resistance
Posted 15/08/2025. IIn this commentary, Phaik Yeong Cheah and colleagues argue that antimalarial resistance and antibacterial resistance raise distinct ethical considerations. Unlike antibacterial resistance, mitigating antimalarial resistance has well-defined goals and does not involve environmental factors or the use in livestock. These differences make it clear that not all microbes should be addressed in the same way, and that interventions must be tailored accordingly.
Use of the International Classification of Diseases to Perinatal Mortality (ICD-PM) with verbal autopsy to determine the causes of stillbirths and neonatal deaths in rural Cambodia: a population-based, prospective, cohort study
Posted 08/08/2025. Perinatal cause-of-death data in low-resource settings are scarce. Applying the WHO's new ICD-PM classification system to verbal autopsy data in rural Cambodia, Kaajal Patel and colleagues identified hypoxia, prematurity, and infection as leading causes. We found that adaptations to ICD-PM were needed to better classify deaths, especially when the timing of death was unknown.

Pavel Matousek, Paul Newton and colleagues from the Medicine Quality Research Group developed a portable laser-based method, SORS, to detect toxic contaminants in medicinal syrups without opening bottles. This innovation addresses the urgent need for accessible screening, following deadly contamination incidents in Asia and Africa. The technology enables rapid, non-invasive testing across supply chains to improve medicine safety.
Risk factors and mitigation strategies of laboratory-acquired infections in research and clinical laboratories worldwide: a systematic review
Posted 01/08/2025. Causes of laboratory‑acquired infections and pathogen escapes are often under‑reported. A review from 2000–2024 identified 712 cases and 17 deaths. Common incidents included needlestick injuries and PPE failures. Research laboratories reported more decontamination issues, while clinical laboratories faced sample‑handling risks. These findings support targeted improvements in laboratory risk management practices. By Sandhya Dhawan
Optimization of heat inactivation protocols for Orientia and Rickettsia species
Posted 30/07/2025. Stuart Blacksell and colleagues evaluated heat inactivation of Orientia tsutsugamushi, Rickettsia typhi, R. conorii, and R. honei at 56 °C, 80 °C, and 90 °C for varying times. All were inactivated at 56 °C for 5 minutes. O. tsutsugamushi showed greater reduction, with time–temperature effects differing by species, highlighting important pathogen‑specific heat‑treatment requirements for biosafety purposes.
Over the counter use of topical corticosteroid for skin conditions among patients before attending skin specialist clinic in Nepal: A qualitative study
Posted 29/07/2025. Why do many patients arrive at skin clinics only after their conditions worsen, despite early treatment? This study from Nepal reveals how over-the-counter steroid use, informal networks, convenience, and customary practices shape care-seeking for skin conditions. These factors also mirror patterns seen in over-the-counter antimicrobial use. By Bipin Adhikari.
Evaluation of the Wondfo G6PD/Hb Test for glucose-6-phosphate dehydrogenase deficiency: preliminary performance, matrix equivalence, and usability
Posted 25/07/2025. Increased availability of validated G6PD tests can enhance diagnostic capacity in LMIC for vivax radical cure and neonatal health. This preliminary evaluation of a new point-of-care G6PD quantitative test showed excellent performance in frozen and fresh samples collected in Thailand (SMRU) and USA. A WHO pre-qualification study is now ongoing in Brazil and Thailand. By Germana Bancone
Comparative virulence analysis of seven diverse strains of Orientia tsutsugamushi reveals a multifaceted and complex interplay of virulence factors responsible for disease
Posted 17/07/2025. Scrub typhus, caused by Orientia tsutsugamushi, varies in severity depending on the bacterial strain. Jeanne Salje and colleagues compared seven strains in mice and found no single predictor of virulence. Instead, disease severity results from multiple bacterial genes influencing immune responses. These findings could inform future vaccine development and diagnostics.
Single low dose primaquine to block the transmission of Plasmodium falciparum—proposed stand-alone and ACT-adapted regimens
Posted 16/07/2025. At long last and almost 13 years since the WHO recommendation, we now have evidenced-based regimens of single low dose primaquine to block the transmission of Plasmodium falciparum and help eliminate artemisinin and partner drug resistant malaria which is currently spreading rapidly across eastern Africa and beyond.

Why should we be concerned by internalised racism in global health?
Posted 15/07/2025. Internalised racism is an overlooked concept that can shape how professionals from historically marginalised backgrounds see themselves within global health. This essay by Bipin Adhikari and colleagues offers a space for reflection on how deep-rooted racial hierarchies may quietly influence identity, behaviour, and institutional culture. Advancing equity in global health also means understanding how these patterns take hold within us.
Pneumococcal density and respiratory co-detection in severe pediatric pneumonia in Laos
Posted 03/06/2025. Worldwide, acute respiratory infection is the leading cause of morbidity and mortality in children. The first study in Laos on respiratory pathogen co-detection was conducted at Mahosot Hospital and confirmed an association between pneumococcal density and influenza but not between respiratory syncytial virus and severe pneumonia in children less than 5 years old. By Audrey Dubot-Peres and Sue Lee.
