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.

Bei vielen schwer erkrankten Menschen muss mit einer im Verhältnis zu anderen schweren ARE längeren Behandlung mit Beatmung/zusätzlichem Saürstoffbedarf gerechnet werden. Da weder eine Impfung noch eine spezifische Therapie derzeit zur Verfügung stehen, müssen alle Massnahmen darauf ausgericht...et sein, die Verbreitung der Erkrankung so gut wie möglich zu verlangsamen. Es gibt 3 Komponenten: A) Verhinderung der Ausbreitung durch Fallfindung und Absonderung von engen Kontaktpersonen, B) soziale Distanz schaffen und C) gezielter Schutz von vulnerablen Gruppen, die aktiviert und intensiviert werden müssen ent-sprechend der jeweils aktuellen Lage

The Social and Behaviour Change Communication (SBCC) Strategy for the Prevention of the Re-establishment of Malaria Transmission in Timor-Leste forms part of the National Strategic Plan (NSP) for 2021–2025. The strategy aims to support Timor-Leste's efforts to sustain malaria elimination by promot...ing responsive and preventive behaviours through targeted communication and community engagement. Created in collaboration with the Ministry of Health, the WHO, the Global Fund and other stakeholders, the SBCC strategy implements recommendations from the 2020 external review of the National Malaria Programme. Building on previous BCC initiatives (2015–2020), it emphasises surveillance, diagnosis, treatment and vector control, particularly focusing on vulnerable populations. The SBCC strategy provides partners and implementers with a dynamic guide to designing context-specific communication interventions that support malaria elimination and prevent the re-establishment of transmission.
