Answer

Risk factors for children are less well defined than they are in adults. Apparent predisposing factors, from reported cases, include the following: [4, 8]

  • Immunodeficiency (primary or secondary) - Malignancies, severe combined immunodeficiency, chronic granulomatous disease, organ transplantation, and treatment with corticosteroids

  • Preexisting respiratory disease - Acute or chronic lung disease, asthma, tracheal stenosis, and tracheobronchomalacia

  • Young age (especially neonates)

  • Water births

Rare cases of legionellosis are reported in children who are immunocompetent and who lack predisposing conditions.
