What are the primary data sources for the Risk Engine?

The Risk Engine is grounded in stratified epidemiological priors from global surveillance bodies like the World Health Organization (WHO) and the U.S. Centers for Disease Control (CDC). All base transmission coefficients are derived from a matrix of peer-reviewed, act-specific risk values from established scientific studies.

Is the risk percentage 100% accurate?

The result is a statistical probability, not a definitive diagnosis or a guarantee. It represents a highly educated estimate based on the best available population-level data. Individual circumstances can vary. The report is a tool for understanding probability, not a substitute for an actual HIV test from a healthcare professional.

How the Risk Engine Works

The Risk Engine operates as a multi-phase probabilistic inference system...

Phase V: Phenomenological Translation

...The engine's data priors are continuously updated via a recursive data assimilation pipeline to maintain model accuracy.
