Legionnaires' disease occurred in a 3-year-old boy with Down's syndrome. His illness was characterized by bilateral pneumonia, high fever, and response to erythromycin. The diagnosis was made by demonstrating Legionella pneumophila, serogroup 1, in sputum with a direct fluorescent antibody stain. L pneumophila antigen was detected in urine by an enzyme-linked immunospecific assay. The diagnosis was confirmed by a more than fourfold rise in serum antibody titer. Although Legionnaires' disease appears to be uncommon in children, it should be included in the differential diagnosis of pneumonia in the immunocompromised child.
