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.

The Global Programme on Tuberculosis & Lung Health of the World Health Organization (WHO/GTB) is now combining all current recommendations into one overall set of consolidated guidelines on TB. The guidelines contain recommendations pertaining to all areas related to the programmatic management of T...B (e.g. screening, preventive treatment, diagnostics, patient support, and the treatment of drug-susceptible TB and DR-TB). The consolidated guidelines contain modules specific to each programmatic area.

Strategy for Increasing the use of Modern Contraceptives in Nigeria
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.

In 2019, the Task Force on Fiscal Policy for Health concluded that taxes on tobacco, alcohol, and sugar-sweetened beverages were a highly effective but greatly underused policy tool to reduce consumption, save lives, and raise domestic resources. The Task Force estimated that if all countries increa...sed their excise taxes to raise prices by 50 percent, over 50 million premature deaths could be averted worldwide over the next 50 years while
raising over USD 20 trillion of additional revenue. Since the Task Force first convened, the world has faced a “polycrisis,” including a global pandemic, an economic recession, and the outbreak of wars in Europe and the Middle East. Against this backdrop, the world has also experienced prolonged health and fiscal crises. Health systems, weakened by the COVID-19 pandemic, lack sufficient financing to rebuild and respond to the surging noncommunicable diseases epidemic caused by uncontrolled risk factors such as tobacco, alcohol, and sugar consumption. Opportunities to raise domestic resources are limited and debt burdens have squeezed budgets. The period from 2019 to 2027 risks becoming a “lost decade” for health and social policies, with 110 countries facing little prospect of any
ability to raise government revenues beyond current levels. In this paper, we describe the current health and fiscal crises and review the contribution that health taxes could make in turning around this dire situation. We conclude that taxes on tobacco, alcohol, and
sugar-sweetened beverages are an ideal policy solution—good for the budget and good for health. These taxes are relatively quick to implement, and, unlike other taxes, do not put economic growth at risk—a vital benefit in the current era.
