About the tool
Created for The Journal of the American Medical Association, this interactive data visualization tool shows estimated trends in HIV/AIDS death, incidence, and prevalence worldwide and by country for the years 1990 to 2013. Estimated results were derived using a modified version of the UNAIDS Spectrum model based on a review of mortality on and off antiretroviral therapy. In concentrated epidemics we calibrated Spectrum to fit vital registration data corrected for misclassification of HIV deaths. In generalized epidemics we minimized a loss function to select epidemic curves most consistent with prevalence and demographic data. We incorporated a combination of data and reports from surveys, censuses, vital registration, and sample registration. We estimated 95% uncertainty intervals (UIs) for all values.
