However, COVID-19-related pneumonia may be increasing since the omicron variant of COVID-19 appeared. <strong><em>Methods:</em></strong> The clinical differences between COVID-19-related and influenza-related pneumonia patients were retrospectively investigated in patients hospitalized from January 2022 to December 2023. <strong><em>Results: </em></strong>COVID-19-related and influenza-related pneumonias were found in 46 of 285 (15.8%) and 6 of 12 (50.0%) patients, respectively (p&lt;0.001). Their mean ages were 75.5 (45-93) years and 53.8 (19-73) years in COVID-19-related and influenza-related pneumonia cases, respectively (p=0.002). Aspiration pneumonia was more common in COVID-19-related pneumonia (28/46=60.9%) than in influenza-related pneumonia patients, and it was treated by sulbactam/ampicillin (31/46=67.4%). The influenza-related pneumonia patients were more often infected in the work place (2/6=33.3%) and not vaccinated (4/6=66.7%), compared with COVID-19-related patients. Death occurred in 7 of 46 (15.2%) COVID-19 patients, but none of 6 influenza-infected patients died. <strong><em>Conclusions:</em></strong> These data suggest that COVID-19-related pneumonia presented as aspiration pneumonia in older patients, although influenza-related pneumonia was more common in younger and non-vaccinated patients and might be associated with immune mechanisms during the omicron variant surge era.</p> Masafumi Seki, Chie Kubosawa, Makoto Ono, Fumitaka Kamoshita, Atsuko Shimizu, Haruka Karaushi, Noriyuki Watanabe, Kotaro Mitsutake Copyright (c) 2024 Global Journal of Epidemiology and Infectious Disease https://www.scipublications.com/journal/index.php/gjeid/article/view/913 Sat, 06 Apr 2024 00:00:00 +0000
