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.

J Fungi (Basel) . 2019 Aug 16;5(3):75. doi: 10.3390/jof5030075 . Namibia is a sub-Saharan country with one of the highest HIV infection rates in the world. Although care and support services are available that cater for opportunistic infections related to HIV, the main focus is narrow and predominan...tly aimed at tuberculosis. We aimed to estimate the burden of serious fungal infections in Namibia, currently unknown, based on the size of the population at risk and available epidemiological data. Data were obtained from the World Health Organization (WHO), Joint United Nations Programme on HIV/AIDS (UNAIDS), and published reports.

The introduction of “Treat All” (TA) has been promoted to increase the effectiveness of HIV/AIDS treatment by having patients initiate antiretroviral therapy at an earlier stage of their illness. The impact of introducing TA on the unit cost of treatment has been less ...clear. The following study evaluated how costs changed after Namibia’s introduction of TA in April 2017.

Rising levels of inflation, debt and macrofiscal tightening are putting expenditures on the social sectors including health under immense scrutiny. Already, there are worrying signs of reductions in social sector investments. However, even before the pandemic, evidence showed the significant returns... on investments in health equity and its social determinants. Emerging data and trends show that these potential returns have increased during the COVID-19 pandemic - investments in social determinants can mitigate widespread reductions in human capital and the increasing likelihood of costly syndemics, while promoting access to healthcare innovations that have thus far been inequitably distributed. Therefore, we argue that, despite immediate fiscal pressures, this is exactly the time to invest in health equity and its broader social determinants, as the returns on such investments have never been greater.

This publication provides a problem analysis of the U.S. cuts in global health and derives concrete recommendations for action for medical actors. The focus is on analyzing the direct effects on health-specific development cooperation.
Developed under the USAID-supported HRH2030 Capacity Building for Malaria (CBM) initiative, this guide offers a comprehensive framework for advising National Malaria Control Programmes (NMCPs) through the use of long-term technical advisors (LTTAs). It sets out key practices for implementing partner...s and advisors, covering advisor selection, onboarding, contextual analysis and capacity-building strategies at individual and organisational levels. It emphasises collaborative work planning, continuous performance monitoring, stakeholder engagement and the use of assessment tools such as the Capability Maturity Model (CMM) and the Organisational Development Assessment (ODA). The guide is designed to strengthen the leadership and operational effectiveness of NMCPs, promoting sustainable improvements in malaria control through structured mentorship, knowledge transfer and strategic partnerships.

The health impacts of climate change are no longer a distant threat. They are being felt here and now and becoming more extreme.
To address these threats, the WHO Asia-Pacific Centre for Environment and Health in the Western Pacific Region (ACE) was established in 2019 through a partnership with ...the Seoul Metropolitan Government, the Ministry of Climate, Energy and Environment of the Republic of Korea and the World Health Organization (WHO).
The Centre’s mission is to strengthen cooperation and drive action where environment and health meet. This focus on environmental health has created a strong foundation for system-wide change.
This strategic plan builds directly on that work. Over the next five years, the Centre will expand its reach, supporting countries to take practical, systems-based action that ensures healthier people, healthier environments and a healthier planet.

The Interim Guidance on Cholera Rapid Diagnostic Tests (RDTs) by the Global Task Force on Cholera Control (GTFCC) provides recommendations for using RDTs to detect cholera in areas with limited laboratory capacity. It highlights the advantages of RDTs, such as rapid detection (within 30 minutes), ea...se of use by non-laboratory personnel, and their role in early outbreak identification and surveillance. However, it emphasizes that RDTs should not replace culture or PCR testing, as they vary in sensitivity (58-100%) and specificity (60-100%). The document advises on proper test selection, storage, training, and integration into national surveillance systems to enhance cholera response efforts.

The report provides an epidemiological update on cholera outbreaks in Haiti as of January 17, 2023. Since the first confirmed cases in October 2022, Haiti has reported 24,232 suspected cases, including 1,742 confirmed cases and 483 deaths. The most affected areas are in the Ouest Department, particu...larly Port-au-Prince. Children aged 1 to 4 years are the most affected group. The ongoing humanitarian crisis, security issues, and limited access to healthcare have worsened the outbreak, hindering epidemiological surveillance and case reporting. The PAHO/WHO is working with Haitian authorities to respond to the outbreak and mitigate its spread.

Malaria in children presents significant clinical challenges, with variations in presentation based on the malaria parasite involved and the child's underlying health conditions. The World Health Organization reports high incidence rates, particularly in sub-Saharan Africa, and emphasizes the import...ance of effective treatment strategies. First-line treatment often involves Artemether-Lumefantrine (ALu), while severe malaria requires careful management and the use of intravenous Quinine. Management protocols emphasize early diagnosis and the monitoring of severe complications to reduce mortality.
