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 document, "Progress on the Prevention and Control of Non-Communicable Diseases," reports on global efforts to reduce the impact of NCDs, such as heart disease, cancer, diabetes, and chronic respiratory diseases, following the commitments made at high-level United Nations meetings. It highlights ...the inadequate progress in meeting the targets set under the Sustainable Development Goal 3.4 to reduce premature NCD mortality by one-third by 2030. Key challenges include insufficient funding, limited implementation of effective interventions, and political and economic barriers, especially in low-income countries. The report calls for strengthened international cooperation, policy reform, and innovative approaches to meet global health targets.

Background. Children and adolescents can develop post-traumatic stress disorder (PTSD) after exposure to a range of traumatic events, including domestic, political or community violence, violent crime, physical and sexual abuse, hijacking, witnessing a violent crime and motor vehicle accidents. This... is particularly critical given the substantial challenge that PTSD poses to the healthy physical, cognitive and emotional development of children and adolescents.

WASH in schools during a cholera response is important due to the strong correlation between WASH and IPC. Not only can it impact the health and well-being of students and staff but also facilitate the potential spread of the disease via the congregation of children and adults from multiple househol...ds. Hygiene can often be more difficult to control with young children and therefore efforts to put in place systems to encourage good practices are essential.
To prevent the spread of cholera in schools, it is important to have clean and safe water sources, proper sanitation facilities, and good hygiene practices in place. This includes providing clean drinking water, hand-washing stations with soap, and education on hygiene and sanitation practices and implement Risk Communication and Community Engagement (RCCE) including dissemination of Information, Education and Communication materials (IEC).

August 2020, The Africa Joint Continental Strategy for COVID-19 is underpinned by the need to limit transmission, prevent deaths and reduce associated harms. Participation by African nations in clinical trials is an essential step to ensure that sufficient data is generated on the safety and efficac...y of the most promising vaccine candidates among the region’s populations.
While current COVID-19 clinical trial activity on the continent is limited, Africa has substantial experience and capabilities to conduct clinical trials for preventative vaccines across a range of diseases, and many organizations on the continent are working tirelessly to help prepare additional trials on potential COVID-19 vaccines. As the number of candidate vaccines in the development pipeline continues to increase, it will be important for organizations responsible for managing clinical trials in the region to partner with vaccine developers to identify potential and appropriate trial locations, provide support to remove any critical obstacles impeding commencement and progress of trials, and to provide oversight ensuring that trials are conducted safely and ethically.

Schistosomiasis is a helminthic infection and one of the neglected tropical diseases (NTDs). It is caused by blood flukes of the genus Schistosoma. It is an important public health problem, particularly in poverty-stricken areas, especially those within the tropics and subtropics. It is estimated th...at at least 236 million people worldwide are infected, 90% of them in sub-Saharan Africa, and that this disease causes approximately 300,000 deaths annually. The clinical manifestations are varied and affect practically all organs. There are substantial differences in the clinical presentation, depending on the phase and clinical form of schistosomiasis in which it occurs. Schistosomiasis can remain undiagnosed for a long period of time, with secondary clinical lesion. Here, we review the clinical profile of schistosomiasis. This information may aid in the development of more efficacious treatments and improved disease prognosis.

There are indigenous communities at high risk in every country of the region. At stake are the lives of 45 million people who belong to more than 800 indigenous peoples. Of these, some 100 are spread across several countries, around 200 maintain voluntary isolation or are in initial contact, and nea...rly 500 are at risk of disappearing due to their reduced numbers. Due to their lower immune resistance, their lack of access to hospital care and the increasing penetration of extractive activities in their territories, indigenous communities in voluntary isolation or in initial contact are cause for particular concern.
Far from hospitals and the news cameras, indigenous people in Latin American become ill and die without access to the means needed to protect themselves. They face the pandemic in conditions of social exclusion, racism and discrimination, which highlights historical inequalities and extreme precariousness in basic and health services.

Dengue is the world’s most important arboviral disease in terms of number of people affected. Over the past 50 years, incidence increased 30-fold: there were approximately 390 million infections in 2010. Globalization, trade, travel,... demographic trends, and warming temperatures are associated with the recent spread of the primary vectors Aedes aegypti and Aedes albopictus and of dengue. Overall, models project that new geographic areas along the fringe of current geographic ranges for Aedes will become environmentally suitable for the mosquito’s lifecycle, and for dengue transmission. Many endemic countries where dengue is likely to spread further have underdeveloped health systems, increasing the substantial challenges of disease prevention and control. Control focuses on management of Aedes, although these efforts have typically had limited effectiveness in preventing outbreaks. New prevention and control efforts are needed to counter the potential consequences of climate change on the geographic range and incidence of dengue, including novel methods of vector control and dengue vaccines.

Asthma is the most common noncommunicable disease in children, and among the most common in adults. According to the most recent estimates from the Global Asthma Network Phase I study, around one in 10 children and adults have symptoms of asthma and one in 20 school-aged children have severe asthma ...symptoms, with marked variations in prevalence and in prevalence trends between countries and regions of the world. The Global Burden of Disease Study estimated that asthma caused the loss of 21.6 million healthy years of life (disability-adjusted life years) and 461 069 deaths in 2019. Approximately 90% of the asthma burden of disease is borne by people living low and middle income countries (LMICs). Some countries report very high (up to 90%) rates of uncontrolled asthma. While the prevalence of asthma is highest in countries with a high Socio-Demographic Index (SDI), death rates from asthma are highest in countries with low and lower middle incomes.
