Quantitative Microbial Risk Assessment (QMRA) Wiki

The QMRA Wiki is a community portal for current quantitative information and knowledge developed for the Quantitative Microbial Risk Assessment (QMRA) field. It is an evolving knowledge repository intended to be the go to reference source for the microbial risk assessment community. To learn more about how to contribute edit the wiki, please follow the instructions here.

Explore the Risk Framework

Hazard
IdentificationHazard ID comprises general information about the microbial agent (pathogens) and the adverse consequences to the host from infection and incorporates a wide array of information about the infectious agents.

Dose
ResponseDose-response 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.

Exposure
AssessmentExposure at the simplest level is the dose of the pathogen that an individual ingests, inhales, or comes in contact with. This number feeds into the dose-response models to predict the probability of infection.

Risk
CharacterizationRisk characterization is the integration of information on how much dose was received (from the Exposure Assessment) with how much risk is associated with different doses (from the Dose Response Assessment) to estimate a probability of harm (that is, risk).

Risk
ManagementThe goal of risk management is to reduce or eliminate risks and the negative consequences associated with risks. Risk can be managed using many different strategies and is most effective when it is informed through risk characterization.

Case studies provide real world examples of the risk assessment framework put into action.
