The purpose of these reports is to provide a descriptive annual summary of the reporting and burden of Legionnaires’ disease within the United States. Topics include case count and incidence, seasonality and geographic distribution, demographic characteristics, potential exposure sources, disease severity indicators, and diagnostic laboratory test results. Data from two surveillance systems were combined to provide a more comprehensive understanding of the national burden of Legionnaires’ disease.
