We report a case of acute empyema caused by\n \n Gemella morbillorum<\/jats:italic>\n <\/jats:styled-content>\n following COVID\u201019 infection in a previously healthy man in his mid\u201040s. He developed persistent fever and cough after COVID\u201019, and left pleural effusion was detected 3\u2009weeks later. Despite meropenem therapy, his symptoms persisted, prompting referral to our institution. Imaging showed multiloculated pleural effusion compatible with stage II empyema, and video\u2010assisted thoracoscopic surgery was performed.\n \n G. morbillorum<\/jats:italic>\n <\/jats:styled-content>\n was isolated from intraoperative specimens, and he recovered uneventfully. This case highlights that even healthy, non\u2010elderly individuals may develop significant bacterial superinfection after COVID\u201019. Clinicians should therefore consider secondary bacterial infections, including empyema, when persistent or recurrent symptoms occur following COVID\u201019.\n <\/jats:p>","DOI":"10.1002\/rcr2.70458","type":"journal-article","created":{"date-parts":[[2026,1,5]],"date-time":"2026-01-05T23:40:42Z","timestamp":1767656442000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Acute Empyema due to\n Gemella morbillorum<\/i>\n Following\n COVID<\/scp>\n \u201019 in an Otherwise Healthy Middle\u2010Aged Man"],"prefix":"10.1002","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-4769-0950","authenticated-orcid":false,"given":"Kazumasa","family":"Nanjo","sequence":"first","affiliation":[{"name":"Department of Thoracic Surgery National Hospital Organization Kochi Hospital Kochi City Kochi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shoji","family":"Sakiyama","sequence":"additional","affiliation":[{"name":"Department of Thoracic Surgery National Hospital Organization Kochi Hospital Kochi City Kochi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naoki","family":"Furukawa","sequence":"additional","affiliation":[{"name":"Department of Thoracic Surgery National Hospital Organization Kochi Hospital Kochi City Kochi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroyuki","family":"Hino","sequence":"additional","affiliation":[{"name":"Department of Thoracic Surgery National Hospital Organization Kochi Hospital Kochi City Kochi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2026,1,5]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.36748\/ijswc.4.1_22"},{"issue":"128","key":"e_1_2_9_3_1","article-title":"COVID\u201019: Immunopathogenesis and Immunotherapeutics","volume":"5","author":"Yang L.","year":"2020","journal-title":"Signal Transduction and Targeted Therapy"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa2015432"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.2169\/internalmedicine.54.4950"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1093\/ejcts\/ezv272"}],"container-title":["Respirology Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/rcr2.70458","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1002\/rcr2.70458","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/rcr2.70458","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,1,27]],"date-time":"2026-01-27T05:43:09Z","timestamp":1769492589000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/rcr2.70458"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,1]]},"references-count":5,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2026,1]]}},"alternative-id":["10.1002\/rcr2.70458"],"URL":"https:\/\/doi.org\/10.1002\/rcr2.70458","archive":["Portico"],"relation":{},"ISSN":["2051-3380","2051-3380"],"issn-type":[{"value":"2051-3380","type":"print"},{"value":"2051-3380","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,1]]},"assertion":[{"value":"2025-11-27","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-12-14","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-01-05","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"e70458"}}
