Abstract:

Considerable interest exists in establishing realistic standards for water quality as related to the transmission of infectious disease. The development of such standards is a complicated task that consciously, frequently subconsciously, involves the concept of risk assessment. In the context of our study, risk assessment involves the relationship between the concentration of a pathogen in water and the likelihood of disease occurring in individuals who drink the water. A mathematical model was developed to take into account the variability of the pathogen concentration in water, and hence the dose, as well as the biological variability inherent in the dose-response relationship. An interactive computer program was developed that allows the user to select the organism of interest, the amount of water consumed, the treatment-alternative removal rate, the pathogen concentration, the dose-response model, and the number of susceptible individuals. Based on the users selections, a computer- generated risk curve is produced.
