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.

Biennial Report of the Regional Director
An international field study by African and German theologicans and health workers.
Weekly epidemiological record/Relevé épidémiologique hebdomadaire , 1ST SEPTEMBER 2017, 92th YEAR / no.35 (2017) 501-520
This report, examining the mood of a country that holds the top spot in the Fragile States Index, is based on field research conducted in South Sudan in April and May 2014.
This report presents, for the first time, a global assessment of the extent to which health care facilities provide essential water, sanitation and hygiene (WASH) services. Drawing on data from 54 low- and middle-income countries, the report concludes that 38% lack access to even rudimentary levels ...of water, 19% lack sanitation and 35% do not have water and soap for handwashing. When a higher level of service is factored in, the situation deteriorates significantly. A number of areas require urgent action and WHO will work with UNICEF, Governments and other partners to develop a global plan to address the most pressing needs and ensure that all health care facilities have WASH services.

Regional dashboards on 16 key indicators highlight where progress is being made o...r lagging. There is progress overall, but not at the level required to achieve the 2030 goals. There are some areas where progress has stalled or is reversing, namely neonatal mortality, gender inequalities and health in humanitarian settings.

The Global Vaccine Action Plan (GVAP) 2011-2020, endorsed by Member States during the May 2012 World Health Assembly, has set ambitious targets to improve access to immunization and tackle vaccine-preventable diseases. This responsibility has been translated into firm commitments in February 2016, t...hrough the signature of the Addis Declaration on Immunization (ADI) by African Ministers and subsequently endorsed by the Heads of States from across Africa at the 28th African Union Summit held in January 2017. This commitment from the highest level of government comes as a catalyst to immunization efforts on the continent to deliver on the promise of universal immunization

Globally, in low-income countries, the average newborn mortality rate is 27 deaths per 1,000 births, the report says. In high-income countries, that rate is 3 deaths per 1,000. Newborns from the riskiest places to give birth are up to 50 times more likely to die than those from the safest places.
...>
The report also notes that 8 of the 10 most dangerous places to be born are in sub-Saharan Africa, where pregnant women are much less likely to receive assistance during delivery due to poverty, conflict and weak institutions. If every country brought its newborn mortality rate down to the high-income average by 2030, 16 million lives could be saved.
More than 80 per cent of newborn deaths are due to prematurity, complications during birth or infections such as pneumonia and sepsis, the report says. These deaths can be prevented with access to well-trained midwives, along with proven solutions like clean water, disinfectants, breastfeeding within the first hour, skin-to-skin contact and good nutrition.

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.

The Newborn Situational Analysis reports of 2009 and 2011, as well as the “Bottleneck analysis on neonatal health” of 2013, culminated in the Nigeria launch of “Call to action on Newborn health” at the first National Newborn Health Conference in 2014. This call to action provided the framewo...rk for the development of the Nigeria Every Newborn Action
Plan (NiENAP). The NiENAP lays out a vision to end preventable stillbirths and newborn deaths by accelerating progress and scaling up evidence- based high-impact and cost effective interventions. The plan is guided by the principles of country-leadership, integration, accountability, equity, human rights, innovation and research. This blue print outlines our commitment as government and stakeholders to repositioning newborn health as we implement approaches that impact on the lives of newborns for improved health outcome.
