摘要

A field investigation of a recent disease outbreak resulting in three deaths, 34hospitalizations and a total of 240 documented cases of diarrhea was linked through on-site data gathering and use of a distribution system model to the public water supply. The pathogenic agent, E. coli serotype 0157:H7, was isolated from patient's feces and cases were restricted to people using public water supply. Untreated ground water quality was not a factor but some disturbance in the distribution system, possibly 2 line breaks allowed contaminants to enter the water supply. This is the first time a distribution system model has been used to show that the pattern of illness occurrences in a waterborne outbreak study were related to water movement patterns in the distribution network.
