Epidemiological parallels of community-acquired pneumonia, influenza and ARVI in Moscow

Abstract

The problem of community-acquired pneumonia continues to be urgent due to high incidence, hospital admission rates, and mortality. The objective of the study is to characterize epidemiological parameters of incidence and mortality of community-acquired pneumonia, influenza, and ARVI in Moscow. Subjects and methods . The incidence and mortality of community-acquired pneumonia, influenza, and ARVI among different population groups in Moscow were analyzed. The Pearson correlation coefficient (rxy) was calculated to assess the relationship between incidence of pneumonia, influenza, and ARVI. Data were analyzed using IBM SPSS Statistics IBM statistics, version 23.0. Results. Over the studied period of long-term changes in the incidence of community-acquired pneumonia among all population groups, a pronounced upward trend is observed. The highest incidence rates of community-acquired pneumonia in Moscow are registered among under in infants one year, 1-2 years old and 3-6 years old pediatric patients. The months of the maximum incidence of community-acquired pneumonia in adults coincide with the months of the maximum incidence of influenza (January - February). The maximum incidence of community-acquired pneumonia among children 15-17 years old and 0-14 years old is registered 2 months earlier than with influenza. The highest mortality of pneumonia is observed after 1-2 months after the maximum incidence of ARVI and influenza, which is due to delayed mortality as a result of the exacerbation of chronic diseases. The authors suggest considering simultaneous vaccinations against influenza and pneumococcal infection among people over 65 years old and high-risk groups during the pre-season vaccination against influenza.
