Prevalence and Incidence Calculator (version 1.03)

The Prevalence and Incidence Calculator supports the estimation of HIV prevalence and incidence and provides full variance/covariance through analysis of cross-sectional surveillance data, including biomarkers, supporting classification of HIV cases as recently or non-recently acquired. The underlying logic in this calculator is core functionality of the R package inctools. While the correct use of the app and the underlying tools package does not require any detailed technical knowledge about the theoretical underpinnings, an understanding of the core concepts is useful. A linked document provides technical background for transparency/reproducibility, and helps potential users orient themselves. A Help tab/document provides a walkthrough of the preloaded examples. Users working to provide national level estimates as part of an interaction with UNAIDS are invited to contact the maintainers for assistance and are requested to provide any notification of possible errors, as well as to give general feedback about clarity and functionality.
