MEDICAL AND SOCIAL FEATURES OF THE FORMATION OF INFECTIOUS MORBIDITY OF CHILDREN OF THE METROPOLIS

Abstract

The study of the features of infectious morbidity, especially during the spread of a new coronavirus infection, is of particular relevance in the organization of medical care to the population and ensuring anti-epidemic safety. A comprehensive study of the infectious morbidity of children aged 0-17 years in St. Petersburg in 2016–2020 was conducted. The indicators of infectious morbidity of the child population by groups of infectious diseases and individual nosologies, by different ages, living conditions and clusters of city districts were assessed. Differences in the sanitary state of the external environment in the districts of St. Petersburg were revealed, such as chemical contamination of surface waters in industrial and central areas, an increase in unsatisfactory samples of bacterial contamination, especially in the historical center, an unsatisfactory situation of chemical contamination of soils in industrial and residential areas. During the observation period, there was a decrease in the general infectious morbidity among children in the city, only in 2018 and 2019 an increase in this indicator was recorded in suburban areas. The highest incidence of intestinal infections was observed in residential areas, the lowest in suburban areas. While maintaining the general trend of reducing the incidence of acute viral hepatitis, an increase in industrial and suburban areas in 2017 and 2018 was noted. The highest flu incidence rates were in residential areas, the lowest — in the historical center. In all groups of districts of the city in 2020 compared to 2019 an increase in the incidence of viral pneumonia was recorded, the most significant in industrial and suburban areas. The incidence of mainly sexually transmitted infections in 2020 decreased in the city as a whole, but in residential, industrial and central areas there was an increase in the incidence of gonococcal infection. The study of the features of the formation of infectious morbidity will contribute to the optimization of organizational and anti-epidemic measures.
