This report investigates the impact of potential misclassification of samples on HIV prevalence estimates for 23 surveys conducted from 2010-2014. In addition to visual inspection of laboratory results, we examined how accounting for potential misclassification of HIV status through Bayesian latent ...class models affected the prevalence estimates. Two types of Bayesian models were specified: a model that only uses the individual dichotomous test results and a continuous model that uses the quantitative information of the EIA (i.e., the signal-to-cutoff values). Overall, we found that adjusted prevalence estimates matched the surveys’ original results, with overlapping uncertainty intervals. This suggested that misclassification of HIV status should not affect the prevalence estimates in most surveys. However, our analyses suggested that two surveys may be problematic. The prevalence could have been overestimated in the Uganda AIDS Indicator Survey 2011 and the Zambia Demographic and Health Survey 2013-14, although the magnitude of overestimation remains difficult to ascertain. Interpreting results from the Uganda survey is difficult because of the lack of internal quality control and potential violation of the multivariate normality assumption of the continuous Bayesian latent class model. In conclusion, despite the limitations of our latent class models, our analyses suggest that prevalence estimates from most of the surveys reviewed are not affected by sample misclassification.

We investigate whether and to what extent Chinese development finance affects infant mortality, combining 92 demographic and health surveys (DHS) for a maximum of 53 countries and almost 55,000 sub-national locations over the 2002-2014 period. We address causality by instrumenting aid with a set of ...interacted variables. Variation over
time results from indicators that measure the availability of funding in a given year. Cross-sectional variation results from a sub-national region’s “probability to receive aid.” Controlled for this probability in tandem with fixed effects for country-years and provinces, the interactions of these variables form powerful and excludable instruments. Our results show that Chinese aid increases infant mortality at sub-national scales, but decreases mortality at the countrylevel. In several tests, we show that this stark contrast likely results from aid being fungible within recipient countries.

Nigeria’s healthcare system faces significant challenges in financing and quality, impacting the delivery of services to its growing population. This study investigates healthcare workers’ perceptions of these challenges and their implications for healthcare policy and practice. A cross-sectiona...l survey was conducted with 600 healthcare professionals from eight states across Nigeria, representing a variety of healthcare occupations. Participants completed a questionnaire that assessed their perceptions of healthcare financing, quality of care, job satisfaction, and motivation using a 5-point Likert scale, closed- and open-ended questions. Descriptive statistics, Chi-squared test, and regression analysis were used to analyze the data. The findings revealed that healthcare workers were generally not satisfied with the current state of healthcare financing and system quality in Nigeria. Poor funding, inadequate infrastructure, insufficient staffing, and limited access to essential resources were identified as major challenges.

Activity Brief.Formative research revealed that gold miners in remote regions of Guyana viewed malaria as an unavoidable and minor risk compared to other dangers. Building on these insights, Breakthrough ACTION co-created the 'Lil Mosquito, Big Problem' (LMBP) social and behavioural change campaign,... which targeted miners in malaria-endemic areas (Regions 7 and 8). Adopting a human-centred design approach, the campaign collaborated with the Ministry of Health, mining organisations, and miners throughout its development. LMBP used visual, low-literacy materials featuring animated and live-action characters to raise awareness of the risks of malaria and encourage key behaviours such as timely testing, adhering to treatment and consistently using insecticide-treated nets. Launched in 2019 and scaled up until 2024, this multi-channel campaign aimed to change attitudes and improve malaria prevention in these hard-to-reach communities.

La Stratégie nationale de communication pour le paludisme 2017–2020 de la République Démocratique du Congo vise à améliorer les comportements de prévention, de détection et de traitement du paludisme à travers une communication sociale et comportementale (CSC) structurée et contextuelle. ...Élaborée par le Programme National de Lutte contre le Paludisme (PNLP), elle s’inscrit dans la vision d’un accès équitable aux messages de santé et à des services de qualité pour toute la population.
Cette stratégie met l’accent sur l’adoption de pratiques essentielles telles que l’utilisation correcte des moustiquaires imprégnées, le recours systématique au test de diagnostic rapide avant tout traitement, la prise en charge précoce des cas, en particulier chez les enfants de moins de cinq ans et les femmes enceintes, ainsi que l’adhésion complète aux traitements prescrits. Elle cible prioritairement les ménages, les femmes enceintes, les enfants, les agents de santé communautaires, les enseignants, les leaders religieux et les médias.
Pour atteindre ses objectifs, la stratégie mobilise plusieurs canaux de communication, notamment les médias de masse (radio, télévision, affichage), la communication interpersonnelle via les agents communautaires, et des campagnes de mobilisation sociale. Elle identifie également plusieurs obstacles, tels que les croyances erronées, le faible niveau d’éducation sanitaire et les disparités d’accès à l’information dans les zones rurales.
Enfin, le document propose des mécanismes de suivi et d’évaluation clairs, avec des indicateurs pour mesurer l’exposition aux messages, la compréhension, et les changements de comportement au sein des communautés. Cette stratégie vise à créer un environnement favorable à la réduction durable du fardeau du paludisme en RDC.

For COVID-19, as for many infectious diseases, the true level of transmission is frequently underestimated because a substantial proportion of people with the infection are undetected either because they are asymptomatic or have only mild symptoms and thus typically fail to present at healthcare fac...ilities. There may also be neglected or under-served segments of the population who are less likely to access healthcare or testing. Under-detection of cases may be exacerbated during an epidemic, when testing capacity may be limited and restricted to people with severe cases and priority risk groups (such as frontline healthcare workers, elderly people and people with comorbidities). Cases may also be misdiagnosed and attributed to other diseases with similar clinical presentation, such as influenza.
Differences in mortality between groups of people and countries are important proxy indicators of relative risk of death that guide policy decisions regarding scarce medical resource allocation during the ongoing COVID-19 pandemic. This document is intended to help countries estimate CFR and, if possible, IFR, as appropriately and accurately as possible, while accounting for possible biases in their estimation

4th edition
The WHO Laboratory Biosafety Manual (LBM) has been in broad use at all levels of clinical and public health laboratories, and other biomedical sectors globally, serving as a de facto global standard that presents best practices and sets trends in biosafety.
LBM encouraged countries t...o accept and implement basic concepts in biological safety and to develop national codes of practice for the safe handling of biological agents in laboratories within their geographical borders.
This fourth edition of the manual builds on the risk assessment framework introduced in the third edition. A thorough, evidence-based and transparent assessment of the risks allows safety measures to be balanced with the actual risk of working with biological agents on a case-by-case basis.
This novel evidence- and risk-based approach will allow optimised resource use and sustainable laboratory biosafety and biosecurity policies and practices that are relevant to their individual circumstances and priorities, enabling equitable access to clinical and public health laboratory tests and biomedical research opportunities without compromising safety.
