A retrospective analysis was conducted on 2,000 hospitalized patients from December 2022 to February 2023, categorized into mild, moderate, and severe COVID-19 groups. Among these, 300 patients had bacterial coinfections, with\n                    <jats:italic>Klebsiella pneumoniae<\/jats:italic>\n                    and\n                    <jats:italic>Acinetobacter baumannii<\/jats:italic>\n                    identified as the main pathogens. The study found a higher male prevalence and a higher median age, with severe cases mostly affecting individuals aged 70\u201390 years. The drug resistance rates of patients with mild and severe COVID-19 were low. Patients with severe COVID-19 were mainly infected with carbapenem-resistant Enterobacterales (CRE), carbapenem-resistant\n                    <jats:italic>A. baumannii<\/jats:italic>\n                    (CR-Ab) and extended-spectrum \u03b2-lactamase producing bacteria (ESBLs (+)).
