A survey of prevention, testing and treatment policies and practices
This year marked the beginning of the WHO biennium 2016-2017 action plan; this annual report highlights WHO’s key achievements in 2016
It also documents the extraordinary efforts by a broad coalition of government ministries, municipalities, international agencies, community groups, women’s or...ganizations, religious and traditional leaders, media, private sector and donors towards restoration and improving health indicators.

The uneven distribution of HIV risks and burdens across populations is a well-substantiated fact, though seldom publicly acknowledged. Gay men and other men who have sex with men, people who inject drugs, sex workers, and transgender women are 24, 24, 13.5, and 49 times more likely to acquire HIV, ...respectively, than other reproductive aged adults (15 years old and older). Globally, new infections among these key populations account for 45% of all new HIV infections. This figure is likely to be an underestimate, given the intense stigma associated with disclosing and reporting acquisition risks for HIV among gay men, people who use drugs, sex workers, and transgender people. In addition, HIV epidemics in the majority of low- and middle-income countries (90 of 120) have concentrated epidemics among key populations. In countries with more broadly generalized epidemics, risks are still not evenly distributed and key populations still shoulder disease burden that is markedly disproportionate.

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.

This report describes the evolution of mainland Tanzania’s EHB; the motivations for developing the EHBs, the methods used to develop, define and cost them; how it is being disseminated, communicat...ed, and used; and the facilitators (and barriers) to its development, uptake or use. Findings presented in this report are from three stages of analysis: literature review, key informant perspectives and a national consultative meeting.

One important application of digital health in TB patient care is the support that it can lend to medication adherence. TB programmes have already been using short message service (SMS), video-supported treatment (VOT) and event monitoring device for medication support ...(EMM)1 to help patients complete treatment and health-care workers to monitor both daily dosing and treatment continuity
