In the QMRA framework, the dose response assessment phase is an essential quantitative element of the risk estimate. It estimates the risk of a response (for example, infection, illness or death) given a known dose of a pathogen. Dose response models are mathematical functions that describe the dose response relationship for specific pathogens, transmission routes, and hosts. In general, we use the exponential model and the beta-Poisson model to describe dose response relationships. The slope of the beta-Poisson dose response curve is more shallow than the exponential. The exponential model has one parameter and is a special case of the beta-Poisson model (which has two parameters).
