Quantitative Microbial Risk Assessment (QMRA) is an evolving risk science that aims to develop knowledge of the spread and control of infectious diseases. QMRA is particularly useful in the development of control strategies and evidence based policy decisions through the lens of health risk. While most of the models have been developed for human health risks, QMRA is not bound to just the human as an infectious disease host. QMRA models can be developed for animal and plant pathogens as well. 

The QMRAwiki is the QMRA community's portal for current quantitative information and knowledge developed for the Quantitative Microbial Risk Assessment (QMRA) field. It is an evolving repository for QMRA knowledge and data available to the risk analysis community.
