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.

IHME’s Financing Global Health report provides an overview of health spending around the world, with a special focus on investments in health in low- and middle-income countries. The report examines how this funding for health is changing each year and forecasts how it may change in the future. Fi...nancing Global Health examines where money for health originates and what health issues it funds.
This year, Financing Global Health 2023 looks at how interest payments on loans that many countries took out during the COVID-19 pandemic to keep their economies afloat and their people protected are now straining health budgets. It also details how development partners’ investments in health in low- and middle-income countries – development assistance for health – have changed since reaching historic levels during the COVID-19 pandemic, dropping by $19.4 billion between 2021 and 2023, from $84.0 billion to $64.6 billion.

Available evidence demonstrates that direct patient contact and contact with infectious body fluids are the primary modes for Ebola virus transmission, but this is based on a limited number of studies. In this review, the authors address what we know and what ...we do not know about Ebola virus transmission. They also hypothesize that Ebola viruses have the potential to be respiratory pathogens with primary respiratory spread.
