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.

Kenya has great potential for enhancing education for individuals with intellectual disabilities. The fact that it has recognized the need to care for learners with special needs is commendable. In comparison to many African countries, Kenya and Nigeria are ahead in developing programs for special e...ducation in institutions of higher learning, and in starting schools and units for special education. However, a legal mandate is still required as it would seal many loopholes that currently exist. Without it, the assessment of individual with intellectual disabilities cannot be administered correctly and professionally. In this article, the authors present a coherent account on various aspects related to learners with intellectual disabilities in Kenya. No doubt, the issues and challenges identified call for attention by not only the government of Kenya but also those interested in improving the status of learners with intellectual disabilities.

The Global Movement for Mental Health has brought renewed attention to the neglect of people with mental illness within health policy worldwide. The maltreatment of the mentally ill in many low-income countries is widely reported within psychiatric hospitals, informal healing centres, and family hom...es. International agencies have called for the development of legislation and policy to address these abuses. However such initiatives exemplify a top-down approach to promoting human rights which historically has had limited impact at the level of those living with mental illness and their families.

The purpose of this Guide is to set out a simple, user-friendly, step-by-step approach for conducting table-top exercises for use in countries. These are generic guidelines which may be adapted for use at all levels in a country.
Over half a billion children are living in areas with extremely high levels of floods and nearly 160 million children live in areas of high or extremely high droughts. The World Health Organisation (WHO) estimates that 26% of the annual 6.6 million deaths of children under five are linked to environ...ment-related causes and conditions. Children are also disproportionately affected by pollution, not only in terms of death rates, but also in terms of cognitive and physical development. This report illustrates that environmental causes also have an impact on whether children are pushed to work and on the kind of work they engage in, the conditions of work, exposure to dangerous toxicants and the risk of exploitation. However, the report raises more questions than it answers as it is one of the first reports addressing the question, how environmental degradation and climate change affect the vulnerability of children towards exploitation.

On 14 August 2024, the Director-General of the World Health Organization determined that the upsurge of mpox in a growing number of countries in Africa constitutes a new public health emergency of international concern (PHEIC) under the International Health Regulations (IHR) (2005)
For the purposes of this review, we are not setting out what exactly implementing the concept of
planetary health at a national level should or could look like. This is a complicated and nuanced aspect
of moving the concept of planetary health to action that will be highly dependent on the unique ...needs
of each country. We are, however, trying to encourage progress in this regard by identifying openings
that could be leveraged to speed the uptake of the concept of planetary health.

The practice of female genital mutilation (FGM) has proved remarkably tenacious, despite attempts spanning nearly a century to eliminate it. Nevertheless, a number of countries have seen some declines in the practice – at least up until the COVID-19 pandemic, the impact of which is yet to be fully... understood. Other changes in FGM are also evident. These include shifts in attitudes and in the ways the procedure is being carried out.
As the world rallies to accelerate progress against FGM, understanding what drives change in how people think about the practice and act is key to its elimination. Education is one such driver. It is an important mechanism to increase awareness of the dangers of FGM and of groups that do not practise it. Education also fosters questioning and discussion and provides opportunities for individuals to take on social roles that are not dependent on the practice of FGM for acceptance.

Excessive consumption of salt (more than 5 g per day) raises blood pressure, a major risk factor for cardiovascular diseases such as heart disease and stroke, and is the leading cause of death in the WHO European Region. Many countries in the Region have initiated national salt reduction strategies,... including public awareness campaigns, reformulation, and front-of-pack nutrition labelling. However, despite ongoing efforts, surveillance data indicate that salt intake still far exceeds the limits recommended by WHO to protect health.

In a snapshot, fair allocation of vaccines will occur in the following way:
An initial proportional allocation of doses to countries until all countries reach enough quantities to cover 20% of their population
This document is also available in Arabic | Chinese | French | R...ussian | Spanish | Portuguese
A follow-up phase to expand coverage to other populations. If severe supply constraints persist, a weighted allocation approach would be adopted, taking account of a country’s COVID threat and vulnerability.
The document is a final working document and may be adjusted in the future as new information about the vaccines and the epidemiology of COVID-19 becomes available.

During the past five decades, the incidence of dengue has increased 30-fold. Some 50–100 million new infections are estimated to occur annually in more than 100 endemic countries, with a documented further spread to previously unaffected areas; every year hundreds of thousands of severe cases ari...se, including 20 000 deaths; 264 disability-adjusted life years per million population per year are lost , at an estimated cost for ambulatory and hospitalized cases of US$ 514–1394, often affecting very poor populations. The true numbers are probably far worse, since severe underreporting and misclassification of dengue cases have been documented.

Emergencies, in spite of their tragic nature and adverse effects on mental health, are unparalleled opportunities to build better mental health systems for all people in need. This WHO publication shows how this was done in 10 diverse emergency-affected areas
The ERF provides WHO staff with essential guidance on how the Organization manages the assessment, grading and response to public health events and emergencies with health consequences, in support of Member States and affected communities. The ERF adopts an all-hazards approach and it is therefore a...pplicable in all acute public health events and emergencies.
This version (2024) of the WHO ERF has been developed following extensive consultation across the three levels of the Organization and response experiences over the last five years of emergency response. Key areas have been updated to improve the accountability, predictability, timeliness and effectiveness of WHO’s response to emergencies.
