title: [Etiology of the epidemic outbreak of community-acquired pneumonia in children in St. Petersburg].
abstract: In September-December 1998 the epidemic rise of outhospital pneumonia (EP) among children was observed in St. Petersburg, which led to a twofold increase in morbidity rate this year. The study of the etiology of EP during the period of 1998-2001 confirmed the prime role of Streptococcus pneumoniae (74.5%) and, for the first time in Russia, revealed the epidemic outbreak of acute chlamydiosis (Chlamydia pneumoniae), diagnosed in 67.3% of children, the maximum occurrence (87.5%) in 1998 with only 19% of the patients having the disease in the form of monoinfection. The prevalence of S. pneumoniae and C. pneumoniae in the etiology of EP and more severe course of mixed infection suggested that these infective agents played a leading role in the epidemic outbreak of acute respiratory infections in St. Petersburg.
