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.

All countries should increase their level of preparedness, alert and response to identify, manage and care for new cases of COVID-19. Countries should prepare to respond to different public health scenarios, recognizing that there is no one-size-fits-all approach to managing cases and o...utbreaks of COVID-19. Each country should assess its risk and rapidly implement the necessary measures at the appropriate scale to reduce both COVID-19 transmission and economic, public and social impacts.

Zoonotic tuberculosis (TB) is a form of TB in people predominantly caused by the bacterial species, Mycobacterium bovis, which belongs to the M. tuberculosis complex. The implications of zoonotic TB go beyond human health. The organism is host-adapted to cattle, where it is refer...red to as bovine TB, and it also causes TB in other animal species including wildlife. Bovine TB has an important economic impact and threatenslivelihoods.

he National Department of Health (NDOH) presents this Malaria Elimination Strategic
Plan 2019-2023 for the Republic of South Africa. The strategy comes at an important time
as the Southern African Development Community (SADC) heads of state have recently
renewed the commitment to eliminate malari...a in Botswana, Eswatini, Namibia and South
Africa by 2020 and in the whole SADC region by 2030, with the target of zero local malaria
cases and deaths. South Africa has made steady progress towards this elimination goal
through the implementation of evidence-based malaria policies aligned to the World Health
Organization’s (WHO) Global Technical Strategy.

Senegal’s substantial and sustained progress against malaria is an inspiring public health success story, and a source of potential lessons for other countries on the path to elimination. This case study describes three major success factors—(1) outstanding leadership and partner engagement, (2)... the achievement and maintenance of high intervention coverage levels, and (3) a thriving data culture—and explores several exciting new opportunities to consolidate and expand upon Senegal’s two decades of impact.

The document titled "Manual for Stratifying Malaria Risk and the Elimination of Foci" by PAHO provides guidance for countries in the Americas on how to systematically assess and classify malaria transmission risk at subnational levels. It outlines a standardized approach to stratification and the id...entification of active transmission foci, helping public health authorities prioritize interventions, allocate resources efficiently, and implement targeted strategies to accelerate progress toward malaria elimination.

All malaria-endemic countries in the Region of the Americas have taken on the challenge to eliminate the disease and to put in place measures to orient their health programs and strategies in that direction. This manual explains how to implement measures to achieve malaria elimination and prevent it...s reestablishment by increasing the intensity and quality of interventions, reorienting initiatives, reducing delays that favor transmission, and ensuring adequate monitoring to adjust interventions.

This technical note provides guidance on actions to accelerate P. falciparum elimination in areas close to achieving this goal without compromising unified malaria elimination efforts (P. vivax - P. falciparum), while contributing to the country's ultimate goal of eliminating malaria overall.
This global guidance was developed to support malaria-free countries and those that are close to malaria elimination to prevent re-establishment. The document outlines key concepts and principles for preventing re-establishment and provides guidance on strategies, interventions, planning and managem...ent. Country examples are included to highlight good practices and illustrate practical applications.
