University of the District of Columbia Outbreak of Escherichia Coli Case Discussion

Question Description

Case Study

In the Summer of 1998, a large outbreak of Escherichia Coli 0157:H7 infections occurred in Alpine, Wyoming. There were 157 ill persons; stool from 71 of them yielded E. Coli 0157:H7. In two cohort studies, illness was significantly associated with drinking municipal water. The unchlorinated water supply had microbiologic evidence of fecal organisms and the potential for chronic contamination with surface water. Among persons exposed to water, the attack rate was significantly lower in town residents than in visitors and decreased with increasing age. The lower attack rate among exposed residents, especially adults, is consistent with the acquisition of partial immunity following long-term exposures. Serologic data, although limited, may support this finding. Contamination of small, unprotected water systems may be an increasing public risk.
