Abstract

This study was aimed at investigation of effects of vaccination against influenza and pneumococcal infection on seasonal morbidity and mortality of influenza, acute respiratory viral infections (ARVI) and community-acquired pneumonia (CAP) in 2012 – 2016 in population of the Central district of Moscow. Methods. Data for the analysis were obtained from official statistic reports and death certificates of patients died in a hospital from flu and CAP. Results of virological investigations of nasopharyngeal swabs for viral RNA of influenza А(H1N1)09v, А(H3N2), and В, and results of bacteriological investigations of sputum and were also used. Results. The morbidity of infectious and parasitic diseases in the Central district of Moscow has decreased by 21.0% in 2016, if compared to 2012, including 19.0% decrease for ARVI. Morbidity of flu increased, probably due to epidemic circulation of influenza virus and improvement in laboratory diagnosis. CAP morbidity was associated with epidemic circulation of influenza and other respiratory viruses and has increased from 2015 to 2016. The highest morbidity of CAP and severe fatal CAP were registered during influenza epidemics. There was a 1.95-fold increase in vaccination coverage against influenza and 3.69-fold increase in vaccination coverage against pneumococcal infection. Though CAP and influenza morbidity increased, vaccination was related to decrease in mortality from CAP in 2016. Conclusion. The results demonstrated that ARVI morbidity in the Central district of Moscow had decreased in 2012 – 2016, but influenza incidence increased. Pneumonia morbidity was associated with epidemic growth of flu and ARVI morbidity. Vaccination coverage against flu and CAP increased and resulted in decreased morbidity of ARVI and decreased mortality from CAP and influenza.
