The research objective was to study prevalence of pneumococcal nasopharyngeal carriage among different age-group populations as well as evaluate annual dynamics of nasopharyngeal carriage levels against incidence rates of community-acquired pneumonia in Khabarovsk city in 2015. The bacteriological research was conducted among 2429 people (1100 adults and 1329 children) suffering from respiratory diseases. The level of pneumococcal carriage of the whole group was equal to 12.3±0.67%. The pneumococcal carriage was registered in all age-groups; its highest levels were diagnosed in children from 1 to 3 years old and in children from 3 to 6 years old (27.0±2.16 and 23.1±1.97%, respectively). The incidence rates of community-acquired pneumonia equaled to 290.2 per 100000 of general population and 687.1 per 100000 of children population. The comparative analysis of annual dynamics of pneumococcal carriage and community-acquired pneumonia incidence rates among general population of Khabarovsk city and separately for children from 0 to 14 years old has shown a correlation between these epidemiologic manifestations. Typically, pneumococcal carriage and incidence rates are the lowest in August; they elevate in September due to influence of common factors that are associated with “mixing” of people. The peculiarity of annual dynamic of community-acquired pneumonia incidence rates is a double-wave course with maximum in April and September. The revealed trends show the correlation between epidemic process of community-acquired pneumonia and undetected epidemic process of pneumococcal infections manifested as pneumococcal carriage.
