Since first being identified in 1976 as the cause of epidemic pneumonia at a Philadelphia American Legion convention, Legionella pneumophila has been recognized as an important cause of community-acquired and nosocomial pneumonia in adults1,2 Reports of Legionella pneumonia in childhood are unusual, however. The incidence of Legionella infection in children is unknown, as the diagnosis is rarely considered. Serosurveys in normal children have shown that by 5 years of age, 20% to 50% of children have at least 1:64 antibody titers to Lp1, suggesting that early exposure may be common.3,4 Nevertheless, fewer than 4% of normal children with community-acquired pneumonia have a fourfold rise in convalescent antibody to Legionella.3-6
