Multiple Sources of the Outbreak of Legionnaires’ Disease in Genesee County, Michigan, in 2014 and 2015

Abstract

This is the first LD outbreak in the United States with evidence for three sources (in 2014): <i>a</i>) exposure to hospital A, <i>b</i>) receiving Flint water at home, and <i>c</i>) residential proximity to cooling towers; however, for 2015, evidence points to hospital A only. Each source could be associated with only a proportion of cases. A focus on a single source may have delayed recognition and remediation of other significant sources of <i>L. pneumophila</i>. https://doi.org/10.1289/EHP5663.
