[Effect of influenza epidemics on acute respiratory morbidity of noninfluenzal etiology].
The use of correlation analysis has made it possible to reveal a high degree of influence exerted by influenza epidemics on morbidity rate in adenoviral, respiratory-syncytial, parainfluenza and mycoplasmic infections among the population. During the months of influenza epidemic considerable concomitant incidence of respiratory-syncytial, adenoviral and especially mixed infections was observed in all age groups in comparison with periods free from influenza epidemic. The study of concomitant morbidity during the periods of 6 influenza A (H3N2) epidemics and 3 influenza B epidemics has shown that the immunosuppressive activity of influenza virus, leading to the activation of other causative agents of acute respiratory diseases, reaches its highest level at the periods of influenza A epidemics characterized by a more intensive and severe clinical course of the disease, such as in influenza A/Victoria/35/72 (H3N2), and drops to a minimum at the periods of influenza B epidemics.
