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.

Indoor residual spraying (IRS) involves applying residual insecticide to potential vector resting sites on the interior surfaces of human dwellings or other buildings. The main aim of IRS is to kill vectors before they are able to transmit pathogens to humans. When carried out correctly, IRS has his...torically been shown to be a powerful intervention to reduce adult vector density and longevity for mosquitoes, sand flies and triatomine bugs and can reduce the transmission of vector-borne diseases.

Severe acute respiratory infections treatment centre: practical manual to set up and manage a SARI treatment centre and a SARI screening facility in health care facilities
The leishmaniases are a group of diseases caused by Leishmania spp., which occur in cutaneous, mucocutaneous and visceral forms. They are neglected tropical diseases (NTDs), which disproportionately affect marginalized populations who have limited access to health care. HIV co-infected patients with... Leishmania infection are highly infectious to sandflies, and an increase in the coinfection rate in an endemic area is likely to increase the effective infective reservoir.

The purpose of cancer screening tests is to detect pre-cancer or early-stage cancer in asymptomatic individuals so that timely diagnosis and early treatment can be offered, where this treatment can lead to better outcomes for some people.
The aim of a cancer screening programme is either to reduc...e mortality and morbidity in a population by early detection and early treatment of a cancer (for example, breast screening) or to reduce the incidence of a cancer by identifying and treating its precursors (such as cervical and colorectal screening).
This short guide is designed to be a quick reference that contains the important ideas about cancer screening. Readers should refer to other publications for comprehensive discussion and detailed guidance on cancer screening programmes.

The Council was established in late 2020 by Dr Tedros Adhanom
Ghebreyesus (Director-General, WHO) to provide new economic thinking – reassessing how health and wellbeing are valued, produced and distributed across the economy. An all-female group of 10 distinguished economists and area experts, t...he Council has focused on reimagining how to put Health for All at the heart of government decision-making and private sector collaboration at regional, national and international levels.

This paper examines the implications of the IMF’s April 2024 macro-fiscal forecast updates on government health expenditure (GHE) across 170 economies through 2029, covering nearly all years remaining to achieve the Sustainable Development Goals (SDGs). The findings reveal wide disparities in gove...rnments' capacities to increase health spending, with differences not only observed across income groups but also within them. Primary concerns focus to two groups of low- and lower middleincome
countries: the first group is projected to experience a contraction in real per capita GHE from 2019 and 2029, threatening to reverse progress toward the health SDG targets, while the other group faces stagnation in real per capita GHE, greatly limiting advancement. The insights presented are crucial for health policymakers and their external partners to respond to evolving macro-fiscal circumstances and stabilize investment growth in health. While increasing the priority of health in spending is a key policy option, it will not be sufficient on its own. Effective responses also
require improving spending efficiency and addressing broader fiscal challenges. Without decisive action, many countries have little chance of achieving the health SDGs.

This report describes findings from a telephone survey with 1,284 people conducted in February 2021. The survey examined how people respond to public health and social measures (PHSMs) to prevent COVID-19. The sample is representative of households with access to a landline or cell phone, but does n...ot include people without access to phones. As phone penetration varies by country, findings should be interpreted with caution.
