EPIDEMIOLOGICAL FEATURES OF ROTAVIRUS INFECTION AMONG HOSPITALIZED CHILDREN IN CHITA

Abstract

The purpose of the study. To study morbidity rate of rotavirus infection for the period 2014-2020 among hospitalized in regional clinical infectious diseases hospital children with acute intestinal infection aged 0 to 17 years.

Materials and methods of research. A retrospective analysis of the digital data of the statistical reports of the clinical infectious diseases hospital of Chita for the period 2014-2020 was carried out. Statistical processing was performed using "Statistica 10".

Results. From 2014 to 2019, the number of hospitalized children with viral diarrhea increased by 2.3 times. In 2020, the number of patients with intestinal infection decreased by 35%. The incidence of bacterial diarrhea in children decreased by 56.5%, and viral diarrhea increased – 69.3%. Rotavirus infection (RVI) accounted for an average of 24,5% among intestinal infections and was 72,1% among other viral diarrheas. The morbidity rate of rotavirus infection in 2020 compared to 2014 became higher by 27.1%, but the proportion of RVI among other viral diarrheas, on the contrary, became lower by 24.8% and mainly among children of the first year of their life – 1.7 times (p˂0.05).

Conclusions. The increase in the morbidity rate of RVI from 2014 to 2020 was revealed against the background of a significant decrease in the number of hospitalized children with acute intestinal infections in 2020. At the same time, there was a decrease in cases of rotavirus diarrhea among children in their first year of life.
