The Spread of RS-virus Infection and other ARVI not Influenza Etiology in Children and Adults in the Regions
Relevance. Respiratory syncytial virus (RSV) is the leading viral cause of acute lower respiratory tract infections in infants and young children in whom this virus is the cause of the primary infection.
Goal. The aim of the study is to study the spread of diseases with MS infection in federal districts of Russia Materials and methods. The Federal Influenza Center collects and automates the processing of weekly information from 24 cities on the number of influenza and acute respiratory viral infections in the total and diagnosed cases (according to polymerase chain reaction) of influenza, RS virus and other acute respiratory viral infections in children (0-2, 6, 7-14 years)
and adults (15 years and older).Results. The average annual incidence of influenza and ARVI, RS virus and Rhino-viral infections, Paragripp and Adenovirus, Boca, Meta and coronas-viral
In order to study the dynamics of the incidence of influenza and ARI in the cities of Russia and the impact of the demographic composition of its population we evaluated changes in the age structure of the population from 1986 to 2014. Considerable changes in the 28 years dynamics of the total incidence of influenza and ARI revealed. The highest incidence rate from 1969 to 1990 gave way to decrease in the incidence from 1991 to 2008 in all cities, especially in megacities, and to increase during the influenza A(H1N1)pdm09 circulation. Reduction of the differences in the incidence of influenza and ARI in cities with different population is noted. From 1969 to 2014 there have been significant changes in the dynamics of influenza and ARI incidence: reduction in the incidence from 1991 in all the cities, especially in megacities, increasing of incidence during the influenza A(H1N1)pdm09 circulation years from 2009 to 2014, and reducing the difference in the incidence of influenza and ARI in cities with varying populations. In most cities, the incidence remained high throughout the observation period. In 2009 - 2014 the incidence has become higher in the Barnaul, Irkutsk, Yakutsk, and Yuzhno-Sakhalinsk, and lower in the Krasnodar and Ulan-Ude compared with the periods from 1986 to 2008. The results from correlation analysis reveal that incidence of influenza and ARI is significantly positively correlated with the age and number of children's groups, more pronounced in the younger age groups, at 95% confidence level. Children 0 - 2 years revealed significant strong correlation in 27 of the 34 cities, the average correlation coefficient, R = 0.75, children 3 - 6 years - a strong (in 16 cities) and the average (in 16 cities), R = 0.63, children 7 - 14 years - a strong (in 9 cities) and average (in 15 cities), R = 0.53, in adults found an association of moderate strength only in 8 cities R = 0.48.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
