A call for national and regional containment, recovery and prevention
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.

More than 40% of the world population is 24 years old or younger, the vast majority of whom live in low- and lower middle–income countries. Globally, a quarter of disability-adjusted life years (DALYs) for mental disorders and substance abuse is borne by this age group and about 75% of mental diso...rders diagnosed in adulthood have their onset before the age of
24 years . Most children and young people in developing countries, however, do not have access to mental health care.

Background report
Community health nurses have the potential to make significant contributions to meet the health care needs of various population groups in a variety of community settings. In order to assess the extent to which CHNs are achieving this potential, WHO conducted a study between 2010 and 2014 that exami...ned the status of community health nursing in 22 countries, 13 of which were experiencing a critical shortage of health care workers. The study revealed that the countries surveyed had the basic and operational framework for optimizing CHN in their health systems as evidenced by the availability of PHC structures to guide interventions. However, challenges were identified related to the education, practice and management of CHNs in these countries. The major challenges identified were: Limited availability of career opportunities; poor worker retention; low recognition for CHNs; inadequate and unsupportive working conditions and environments; absence of educational standards; varying educational entry-level requirements for CHN programmes; and a lack of consensus on the scope of practice for CHNs.

A systematic analysis for the Global Burden of Disease Study 2019. The Lancet Vol.399 Issue 10341 p.2129-2154
Human resources for health (HRH) include a range of occupations that aim to promote or improve human health. The UN Sustainable Development Goals (SDGs) and the WHO Health Workforce 2030 s...trategy have drawn attention to the importance of HRH for achieving policy priorities such as universal health coverage (UHC). Although previous research has found substantial global disparities in HRH, the absence of comparable cross-national estimates of existing workforces has hindered efforts to quantify workforce requirements to meet health system goals. We aimed to use comparable and standardised data sources to estimate HRH densities globally, and to examine the relationship between a subset of HRH cadres and UHC effective coverage performance.

Guidelines for the treatment of human African trypanosomiasis. Web Annex A. Commissioned by WHO Cochrane Response
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.

This is the ninth paper in our series, “Community Health Workers at the Dawn of a New Era”. Community health workers (CHWs) are in an intermediary position between the health system and the community. While this position provides CHWs with a good platform to improve community health, a major cha...llenge in large-scale CHW programmes is the need for CHWs to establish and maintain benefcial relationships with both sets of actors, who may have diferent expectations and needs. This paper focuses on the quality of CHW relationships with actors at the local level of the national health system and with communities.
