Figure 2

Time series of Legionnaires’ disease as a percentage of bacterial pneumonia discharges in Healthcare Cost and Utilization Project hospitals, 26 US states, 1998–2011. The Legionnaires’ disease series is highly seasonal in the Northeast, Midwest, and South. There are very few cases and a lack of apparent seasonality in the West. The changes in the Legionnaires’ disease series after 2002–2003 may result from increased vigilance, testing, and reporting of atypical pneumonias (24).
