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.

A guide for developing a hygiene promotion program to increase handwashing with soap
Ce document a été élaboré par le Programme des urgences sanitaires de l'Organisation mondiale de la santé comme ressource pour la réponse à la flambée du virus d'Ebola (Ebola) en République démocratique du Congo en mai 2018.
Ce document est destiné à guider le travail de communication d...es risques et d'engagement communautaire (CREC) qui est essentiel pour stopper la flambée et prévenir son amplification. Contrairement à d'autres domaines d'intervention, la CREC fait largement appel aux bénévoles, au personnel de première ligne et aux personnes qui n'ont pas reçu de formation préalable dans ce domaine. En tant que tel, le document fournit des informations de base, couvre les aspects socio-économiques et culturels (qui sont connus au moment de la publication), et fournit les derniers conseils et approches fondés sur des données probantes basés sur les Directives de l'OMS : Communiquer les risques dans les situations d'urgence en santé publique, 2018.

Despite the existence of criminal law, which is an important aspect of anti-FGM policies and programmes, there is not much research on the effects of cross-border practices that invalidate the law as a deterrent. Much remains unknown about the practice of cross-border FGM, specifically about gaps in... existing policy and legislation for managing cross-border FGM, as well as whether the existing interventions in the cross-border areas are sufficiently targeted to facilitate changes in social norms

Significant progress has been made in the eradication of three priority diseases in the African Region, as a result of extensive collaboration between the Regional Office, WHO country offices and countries. For example, in August 2020, the region was certified free of wild poliovirus. In the area of... neglected tropical diseases, Guinea worm disease is on the verge of eradication, and 12 member states are within reach of being certified as having eradicated yaws by the end of this year.

New data from the WHO reveal that an estimated 2.2 billion cases of malaria and 12.7 million deaths have been averted since 2000, but the disease remains a serious global health threat, particularly in the WHO African Region. According to WHO’s latest World malaria report, there were an estimated ...263 million cases and 597 000 malaria deaths worldwide in 2023. This represents about 11 million more cases in 2023 compared to 2022, and nearly the same number of deaths. Approximately 95% of the deaths occurred in the WHO African Region, where many at risk still lack access to the services they need to prevent, detect and treat the disease.

The role of evidence in the journey towards universal health coverage is paramount. Financial risk protection monitoring, the major focus of this report, informs where the WHO African Region stands in reducing the financial hardship people face due to health expenses. This report details the status ...of financial risk protection and related trends, the drivers of out-of-pocket (OOP) payments and the impact of the COVID-19 pandemic on financial risk protection. As such, it provides evidence coutries can draw on to develop health financing systems and reforms that mitigate financial barriers to accessing health services. Through analysis of country data, cross-country learning and drawing on the published literature, this report proposes recommendations that countries may adapt to their contexts.
