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 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.

Exposure
Assessment

Risk 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
Characterization

The 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.

Risk
Management

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