Child and Adolescent Health

Severity of acute respiratory infection is higher in developing countries, especially among the socioeconomically underprivileged. Viral pneumonias are more common, especially among children. A prospective hospital-based case control study was undertaken in Bogota between November 2000 and August 2001, aimed to identify factors related to severe low acute respiratory infection (SLARI). Cases were limited to children aged between 2 months and 5 years who filled WHO criteria for SLARI. Controls were children at the same hospital with ARI in a similar age range, but without symptoms of chest drawing. A total of 638 children (277 cases and 361 controls) were included. The most important risk factors included the following: living in borrowed houses (odds ratio (OR) = 2.7; 95% Confidence Interval (CI): 1.06-7.07), sharing the bed (OR = 1.88, CI: 1.0-3.7), living with more than 9 people (OR = 1.82, CI: 1.0-3.51), and living with smokers (OR = 1.4, CI: 1.0-2.05). Of the 114 samples collected (from children at third day after beginning of symptoms), 98 had viruses, sincitial respiratory virus was the most frequently identified virus (41.8%), followed by influenza A virus (3.1%) and influenza B virus (1%). All positive isolates for influenza A and B were sent to the United States Center for Disease Control (CDC) in Atlanta, where they were classified as influenza A/PANAMA/2007/99-like and influenza B/SICHUAN/379/99-like, respectively.
