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 articles in this compendium elaborate on some of the ideas shared at the symposium. Together, they provide a broad view of the dynamic interactions among physical, sexual and brain development that take place during adolescence. They highlight some of the risks to optimal development – includi...ng toxic stress, which can interfere with the formation of brain connections, and other vulnerabilities unique to the onset of puberty and independence. They also point to the opportunities for developing interventions that can build on earlier investments in child development – consolidating gains and even offsetting the effects of deficits and traumas experienced earlier in childhood.

The objective of this project was to list the medical devices required to provide the essential reproductive, maternal, newborn and child health interventions defined by existing WHO guidelines and publications, in order to improve access to these devices in low- and middle-income countries, support... quality of care, and strengthen health-care system. The medical devices are allocated across the reproductive, maternal, newborn and child health continuum of care according to the level of health-care delivery.

For handwashing to be effective, it needs to be practiced consistently and thoroughly. Even when people have access to soap and water, and know how and why to wash their hands, many still do not properly wash their hands consistently at critical times. The handwashing behavior change challenge is no...t only to encourage people to wash their hands with soap, but to do so correctly and at all critical times.
Nudges are one example of a behavior change tool that can encourage people to wash their hands.
Although the evidence base for nudges is still emerging and nudges for handwashing have been tested primarily in single contexts or on a limited scale, this brief and infographic answer some frequently asked questions about nudges and provides examples of how they have been used in efforts to increase handwashing.

Prepared for the Stunting Prevention and Reduction Project - The project Medical Waste Management Plan’s (MWMP) overall objective is to prevent and/or mitigate the negative effects of increased generation of medical waste on human health and the environment. The plan proposes measures to prevent t...he spread of infection and reduce the
exposure of health workers, patients and the general public to the risks from medical waste. The plan is to be used by all project implementation entities to manage medical waste associated with
project activities. These entities will have appropriate procedures and capacities in place to manage the medical waste.

Since December 2016, the El Niño Southern Oscillation (ENSO) has affected Peru, causing heavy rainfall, floods, landslides, hail and electric storms. Although the impact has been particularly serious in the northern coastal regions, levels of affectation are reported in all 24 of the country’s de...partments.

The 2014–2015 Ebola epidemic in western Africa was the longest and most deadly Ebola epidemic in history, resulting in 28,616 cases and 11,310 deaths in Guinea, Liberia, and Sierra Leone. The Ebola virus has been known since 1976, when two separate outbreaks were identified in the Democratic Repub...lic of Congo (then Zaire) and South Sudan (then Sudan). However, because all Ebola outbreaks prior to that in West Africa in 2014–2015 were relatively isolated and of short duration, little was known about how to best manage patients to improve survival, and there were no approved therapeutics or vaccines. When the World Heath Organization declared the 2014-2015 epidemic a public health emergency of international concern in August 2014, several teams began conducting formal clinical trials in the Ebola affected countries during the outbreak.
