Flint water switch led to most Legionnaires’ cases
Most of the more than 90 Legionnaires’ disease cases during the deadly 2014-15 outbreak in the Flint area were caused by changes in the city’s water supply — and the epidemic may have been more widespread than previously believed, according to two studies published Monday. “There was clearly a large proportion of cases that can be attributed to the switch in the water,” said Shawn McElmurry, an environmental engineering associate professor at Wayne State University who leads the research partnership. “While there may not have been a good enough epidemiological investigation at the time, and the data may not have been collected..., this makes it very clear that the increase in the Legionnaires’ cases is attributable to the change in water quality.”
