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 core package of materials provides a comprehensive introduction to the FAST strategy: a focused approach to stopping TB spread in congregate settings. This core package is composed of a booklet, job aids, posters, and a button which serves as a visual reminder to staff and patients of the impor...tance of this strategy in TB control. FAST can be implemented in both general and TB specific medical settings. Download the complete package from the website https://drtbnetwork.org/fast-tb-infection-control-strategy-core-package

Mund-Nasen-Bedeckung im öffentlichen Raum als weitere Komponente zur Reduktion der Übertragungen von COVID-19. Strategieergänzungen zu empfohlenen Schutzmaßnahmen und Zielen (3. Update) Das RKI empfiehlt ein generelles Tragen einer Mund-Nasen-Bedeckung (MNB) in bestimmten Situationen im öffentl...ichen Raum als einen weiteren Baustein, um Risikogruppen zu schützen und den Infektionsdruck und damit die Ausbreitungsgeschwindigkeit von COVID-19 in der Bevölkerung zu reduzieren. Diese Empfehlung beruht auf einer Neubewertung aufgrund der zunehmenden Evidenz, dass ein hoher Anteil von Übertragungen unbemerkt erfolgt, und zwar bereits vor dem Auftreten von Krankheitssymptomen. Ziel des im Epidemiologischen Bulletin 19/2020 veröffentlichten Artikels ist es, eine kurze Übersicht zum fachlichen Hintergrund der Empfehlung zu geben und zu erläutern, welche Dinge hierbei zu berücksichtigen sind.

Sustainable Financing of National HIV Responses
Obesity and diabetes are affecting the peoples of the Americas at high and increasing rates. National surveys demonstrate that obesity is increasing in prevalence among all age groups; 7% to 12% of children under 5 years old and
one-fi fth of adolescents are obese, while rates of overweight and obe...sity among adults approach 60%. Obesity is the major modifi able risk factor for diabetes.

Guidelines on care, treatment and support for women living with HIV/AIDS and their children in resource-constrained settings
The frequency of infectious disease epidemics is increasing, and the role of the health sector in the management of epidemics is crucial in terms of response. In the context of infectious disease epidemics, the use of climate-informed early warning systems (EWS) has the potential to increase the eff...ectiveness of disease control by intervening before or at the beginning of the epidemic curve, instead of during the downward slope.
Currently, the initiation of interventions is heavily reliant on routine disease surveillance systems – data that often arrive too late for preventative response. However, forecasting of disease outbreaks using surveillance and weather information shows promising potential – there also remains further scope to examine seasonal climate forecasts. By combining these elements in new EWS based on computational models, it will be possible to improve both the timeliness and impact of disease control. The World Health Organization (WHO) is strengthening existing surveillance systems for infectious diseases to enable the development of more robust and timely EWS, which has resulted in the rapid development and innovation of EWS for disease outbreaks.

A healthcare worker manual. 2nd edition
The development of this National Manual for the Management of HIV-related Opportunistic Infections and Conditions for use by health care workers at the frontline of our fight against HIV/AIDS is intended to improve their understanding of the causes, preventio...n and appropriate management of opportunistic infections and conditions in adults and adolescents (OIs in children is covered effectively in the Integrated Management of Childhood Illnesses – IMCI – materials). It is also intended to be a practical guide at the clinic level, so as to improve quality of life, treatment outcomes and survival of PLHA. Crucially, this manual uses a “symptom-based” approach to support health care workers at the most basic primary level to be able to effectively initiate the care of PLHA with OIs and refer patients as appropriate (effective triage of patients at the primary care level). The result of this will be to move the management of OIs closer to the patient while ensuring that referral links with higher-level facilities and care is cultivated.
