Norovirus infection in children: an analysis of their own observations

Abstract

Norovirus infection (NVI) ranks second in the structure of intestinal infections of viral etiology in children, is the main cause of outbreaks in all age categories and accounts for up to 50—90% of group cases. The incidence of NVI in the Russian Federation and the Yaroslavl region remains at a fairly high level. Purpose of the study: analyze the clinical and laboratory features of norovirus infection in children. Materials and methods: the article presents literature data on the significance of the problem of NVI in children at the present stage and the results of our own observations of 1332 children hospitalized in the Infectious Diseases Clinical Hospital of Yaroslavl in the period from 2017 to 2022. Results: in the age structure of cases, children of the first three years of life predominated (59.0%); children under 1 year old were 10.3%. An increase in the number of severe forms of NVI has been noted. The severity is due to toxicosis with exicosis. In recent years, NVI occurs in combination with other pathogens of intestinal infections, as well as respiratory viruses, which aggravates the course of the underlying disease, creating an important practical significance of the problem.
