The World Health Organization (WHO) endorses the use of population-based prevalence surveys for estimating the prevalence of trachoma. In general, the prevalence of TF in children aged 1–9 years and the prevalence of TT in adults aged ≥ 15 years are measured at the same time in any district bein...g surveyed. This was the approach of the Global Trachoma Mapping Project, which undertook baseline surveys in > 1500 districts worldwide in order to provide the data required to start interventions where needed.
The survey design recommended by WHO is a two-stage cluster random sample survey, which uses probability proportional to size sampling to select 20–30 villages, and random, systematic or quasi-random sampling to select 25–30 households in each of those villages. In most surveys, everyone aged ≥ 1 year living in selected households is examined.

The Impact of the Zika Outbreak on Women and Girls in Northeastern Brazil
Zambia has about 1.2 physicians, nurses, and midwives per 1000 population while the minimum acceptable density threshold is 2.3 per 1000 population. The estimated shortage of doctors, nurses and midwives in Zambia is about 14,960. However, with the projected population growth the deficit more than d...oubles disproportionately to, 25,849 in 2020, and 46,549 in 2035, at the current rate of HRH production. Worryingly, the human resources for health crisis has persisted for over 20 years. The efforts before and leading up to the development and implementation of the 2013 – 2016 National Training Operational Plan (NTOP) and the National Human Resources for Health Strategic Plan (2011 – 2016) yielded certain achievements, however, the HRH numbers and skill-mix gap remained disturbingly enormous.

The National Strategic Plan for HIV/AIDS and STIs 2017-2024 spells out the objectives and targets that we have jointly committed to achieve. The plan describes the strategies and activities that will need to be implemented on the ground across India's 36 States and Union Territories with the help of... AIDS Control Societies, District AIDS Prevention and Control Units, Regional Institutes, communities, development partners and the private sector. We must urgently scale up our efforts to avert new HIV infections and provide care and treatment to people living with HIV to materialise our commitment of ending AIDS in India by 2030.

Globally, it is estimated that 128.6 million people are currently in need of humanitarian assistance. Of these individuals, approximately one-fourth are women and girls of reproductive age. Although family planning is one of the most life-saving, empowering, and cost-effective interventions for wome...n and girls, it remains an overwhelming gap in emergency responses due to a lack of prioritisation and funding. Consequently, many women and girls are forced to contend with an unmet need for family planning and unplanned pregnancies in addition to the traumas of conflict, disaster, and displacement.

In Myanmar, men who have sex with men (MSM) experience high risk of HIV infection. However, access to HIV testing and prevention services remains a challenge among this marginalized population. The objective of this study was to est...imate population prevalence and correlates of prior HIV testing among young MSM (YMSM) and informs the development of HIV testing and intervention programmes that respond to the specific needs of this population.

A two-week mission was conducted by WASH and quality UHC technical experts from WHO headquarters and supported by the WHO Ethiopia Country Office (WASH and health systems teams) in July 2016, to understand how change in WASH services and quality improvements have been implemented in Ethiopia at nati...onal, sub-national and facility levels; to document existing activities; and through the “joint lens” of quality UHC and WASH, to identify and seek to address key bottlenecks in specific areas including leadership, policy/financing, monitoring and evaluation, evidence application and facility improvements. Ethiopia has implemented a number of innovative and successful interventions.

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.

Regional Network for Equity in Health in east and southern Africa (EQUINET): Disussion Paper 111
The health services delivery system in Zambia is pyramid in structure, with primary healthcare (PHC) services at community level, at the base, followed by first and second level hospitals at distric...t and provincial levels, respectively, and third level (tertiary) services at national level. Notably, primary health services are free in Zambia and health service providers are either governmentowned or not-for-profit facilities.
Over the years, resource constraints have affected the quality and extent of healthcare services at all levels, requiring the mobilisation of additional resources for the sector. In doing so, prioritisation was high on the agenda of health sector reform. The EHB, therefore, prioritises interventions with the highest impact on the population, enabling policy makers to revisit priority diseases and conditions and to cost the services provided at each level of facility. Other key issues in developing the EHB in Zambia have included the need to have cost-effective services and cost per capita of services for more systematic budgeting, to rank interventions and to validate and cost the health benefit package as a whole.

Vitamin A supplementation (VAS) programs targeted at children aged 6–59 months are implemented in many countries. By improving immune function, vitamin A (VA) reduces mortality associated with measles, diarrhea, and other illnesses. There is currently a debate regarding the relevance of VAS, but a...midst the debate, researchers acknowledge that the majority of nationally-representative data on VA status is outdated. To address this data gap and contribute to the debate, we examined data from 82 countries implementing VAS programs, identified other VA programs, and assessed the recentness of national VA deficiency (VAD) data.
