Abstract
The comprehensive study was carried out in one of the gimnasias in Kazan to analyze both dynamics of air in class room during a day and behavior of schoolchildren in case of development of droplet infections. The study involved hygienic, microbiological and mass-spectrometer techniques. The increasing of general microbial dissemination of air of class room during school day was established in case of both absences of ventilation and blind-end ventilation with reduction of exposure time. The increase of specific variety of microbiocenoses of air during school day at the expense of opportunistic and pathogenic microflora of upper respiratory ways and skin under violation of ventilation regimen is demonstrated. The behavior of schoolchildren during period of epidemics of influenza and acute respiratory viral infection (self-treatment, refusal of vaccination, wearing of disposable mask, nonobservance of bed rest, etc.) testifies their inadequate sanitary literacy and promotes prevalence of mentioned above infections. The results of studies indicate necessity of sanitary epidemiological control of microflora of air in school classes of educational institution and development of new methodical approaches using modern techniques (sequence analysis, mass-spectrometry) in evaluation of air microbiocenoses in closed premises dictated by increasing effect of this factor of environment to population health, especially children and adolescents and conditioning reinforcement of focusing of preventive activities to decreasing of risks of development of diseases of respiratory system.
