COVID-19- und influenzaassoziierte Sterbefälle in München ab März 2020 – eine standardisierte Auswertung von Todesbescheinigungen

INTRODUCTION: In light of the current COVID-19 pandemic, the idea arose to conduct a study to comparatively evaluate deaths from two respiratory transmissible infectious diseases (pandemic COVID-19 and seasonal influenza) by means of death certificates received by the health department. METHODS: Death certificates of all deaths in Munich in the death period from 1 March–31 December 2020 were analyzed. The predefined inclusion criteria were the indication of “Corona, COVID-19, SARS-CoV‑2, Influenza (A/B)” on the death certificates. Standardized data entry was performed. The collected data were analyzed descriptively in aggregated form. RESULTS: A total of 12,441 persons died during the study period, 1029 (8.3%) from confirmed COVID-19 and 22 (0.1%) from influenza. The two collectives matched well in the parameters studied. The mean age at death was approximately 80 years and the most common site of death was in hospital. Infectious disease was the cause of death in more than 90% of cases. The most common causes of death were acute respiratory distress syndrome/respiratory failure and multiorgan failure. An average of two previous illnesses were reported, most commonly diseases of the circulatory system and nervous system. There was no influenza death in the second pandemic wave. DISCUSSION: In this study, COVID-19- and influenza-associated deaths were compared for the first time. The deaths of both collectives matched well in the parameters studied, but still require verification in a larger study given the small numbers of influenza cases.
