Mortality and burden of disease attributable to selected major risks
The report reflects on the trends, achievements and challenges in global health over the past decade during which Dr Margaret Chan has been Director-General of WHO. It discusses the role of WHO in dealing with such issues as the rise of noncommunicable diseases, leaps in life expectancy, and emergin...g threats like climate change and antimicrobial resistance.

The figures and findings reflected in the 2019 Humanitarian Needs Overview (HNO) represent the independent analysis
of the United Nations (UN) and its humanitarian partners based on information available to them. While the HNO aims
to provide consolidated humanitarian analysis and data to help inf...orm joint strategic humanitarian planning, many of
the figures provided throughout the document are estimates based on sometimes incomplete and partial data sets using
the methodologies for collection that were available at the time. The Government of Syria has expressed its reservations
over the data sources and methodology of assessments used to inform the HNO, as well as on a number of HNO findings.

The aim of the meeting was to broaden the network’s initiatives. Preliminary work involved integrating laboratory testing for skin NTDs other than Buruli ulcer, such as cutaneous leishmaniasis, mycetoma, leprosy and yaws, while extending the network’s reach to encompass additional laboratories.
Guidelines for the treatment of human African trypanosomiasis. Web Annex A. Commissioned by WHO Cochrane Response
This publication is part of WHO 75th anniversary and aims to capture key successes in public health globally and in Namibia. It includes contributory messages from the Head of State, Prime Minister and the Minister of Health and Social Services.
HAT diagnosis relies on laboratory techniques because clinical signs and symptoms are unspecific. Serodiagnostic tests exist only for Tbg and are based on the detection of specific antibodies, thus they are not confirmatory of infection. With the current low disease prevalence, the positive predicti...ve value of serological tests is particularly low. Field-applicable tools include the card agglutination test for trypanosomiasis (CATT) used mainly in active screening by specialized mobile teams, and the rapid diagnostic tests that are more suitable for individual testing at point-of-care.

HAT diagnosis in non-endemic countries is rare and can be challenging, but alertness and
surveillance must be maintained to contribute to WHO’s elimination goals. Early detection is
particularly important as it co...nsiderably improves the prognosis.

Twenty-Fourth Annual Trachoma Control Program Review, Summary Proceedings
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.

Over the 20 years that followed, this unique partnership has invested more than US$53 billion, saving 44 million lives and reducing the combined death rate from the three diseases by more than half in the countries in which the Global Fund invests.
