The causes of hospital-treated acute lower respiratory tract infection in children
Abstract
Objective: To determine the etiologic agents in children with acute lower respiratory infection.
Design: A survey of a series of patients.
Setting: General pediatric hospital serving an urban population with and without referrals in Helsinki, Finland.
Participants: 135 Finnish children aged 2 months to 15 years (mean, 1.75 years), with clinically defined acute lower respiratory infection (with difficulty of breathing), or found to have fever and a pneumonic infiltrate on chest roentgenogram.
Selection procedures: Consecutive sample on voluntary basis.
Interventions: None.
Main results: Of 121 children with adequate samples, an etiologic diagnosis could be established in 84 (70%): 30 (25%) had bacterial, 30 (25%) viral, and 24 (20%) mixed infections. Antibody assays alone identified the agent in 91% of positive cases.
Conclusions: Bacterial infections are common but generally underestimated in acute lower respiratory infection; serologic methods add significantly to their detection.
