Right now, we are facing an unpredictable and highly dynamic situation as a global community. However, as we have seen from the solidarity, support and power of communities in the HIV epidemic and already in communities responding to the COVID-19 pa...ndemic, the response must not be fear and stigma. We need to build a culture of solidarity, trust and kindness. Our response to COVID-19 must be grounded in the realities of people’s lives and focused on eliminating the barriers people face in being able to protect themselves and their communities. Empowerment and guidance, rather than restrictions, can ensure that people can act without fear of losing their livelihood, sufficient food being on the table and the respect of their community. Ultimately it will give us a more effective, humane and sustainable response to the epidemic.

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 miscl...assification 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.
