While bronchiectasis following tuberculosis is a breeding ground for many bacterial infections\/colonisation, there are few reports of bronchiectasis following COVID\u201019 being a hotbed for bacterial infection\/colonisation. We present a case of a 69\u2010year\u2010old female who developed bronchiectasis following COVID\u201019 pneumonia. The patient had no abnormal findings on chest CT scan for 5\u2009years before COVID\u201019. She developed persistent cough and sputum after COVID\u201019 and chest CT just after COVID\u201019 revealed new bronchiectasis. One year later, she was introduced to our department for repeating exacerbation of chronic respiratory infection, and <jats:styled-content style=\"fixed-case\"><jats:italic>Haemophilus influenzae<\/jats:italic><\/jats:styled-content> was detected in sputum. This case highlights the potential for <jats:styled-content style=\"fixed-case\"><jats:italic>H. influenzae<\/jats:italic><\/jats:styled-content> to infect\/colonise in post\u2010COVID\u201019 bronchiectasis. While there have been few reports of chronic airway infection complicating bronchiectasis after COVID\u201019 until now, long\u2010term respiratory follow\u2010up and management of bacterial colonisation are crucial in these patients in the future. This case suggests that COVID\u201019 can predispose individuals to bacterial infection in the setting of bronchiectasis, emphasising the need for vigilance in post\u2010COVID\u201019 airway management.<\/jats:p>","DOI":"10.1002\/rcr2.70287","type":"journal-article","created":{"date-parts":[[2025,7,24]],"date-time":"2025-07-24T04:14:42Z","timestamp":1753330482000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["A Case of <scp><i>Haemophilus influenzae<\/i><\/scp> Colonisation in Bronchiectasis Following <scp>COVID<\/scp>\u201019: Post\u2010<scp>COVID<\/scp>\u201019 Bronchiectasis as a Structural Hotbed for Chronic Airway Infections"],"prefix":"10.1002","volume":"13","author":[{"given":"Issei","family":"Oi","sequence":"first","affiliation":[{"name":"Division of Respiratory Medicine Center for Respiratory Diseases, National Hospital Organization Kyoto Medical Center  Kyoto Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuta","family":"Okada","sequence":"additional","affiliation":[{"name":"Division of Respiratory Medicine Center for Respiratory Diseases, National Hospital Organization Kyoto Medical Center  Kyoto Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naoki","family":"Fujimoto","sequence":"additional","affiliation":[{"name":"Division of Respiratory Medicine Center for Respiratory Diseases, National Hospital Organization Kyoto Medical Center  Kyoto Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Saiki","family":"Yoshimura","sequence":"additional","affiliation":[{"name":"Division of Respiratory Medicine Center for Respiratory Diseases, National Hospital Organization Kyoto Medical Center  Kyoto Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shogo","family":"Toyama","sequence":"additional","affiliation":[{"name":"Division of Respiratory Medicine Center for Respiratory Diseases, National Hospital Organization Kyoto Medical Center  Kyoto Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takanori","family":"Ito","sequence":"additional","affiliation":[{"name":"Division of Respiratory Medicine Center for Respiratory Diseases, National Hospital Organization Kyoto Medical Center  Kyoto Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1246-2339","authenticated-orcid":false,"given":"Takuma","family":"Imakita","sequence":"additional","affiliation":[{"name":"Division of Respiratory Medicine Center for Respiratory Diseases, National Hospital Organization Kyoto Medical Center  Kyoto Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Osamu","family":"Kanai","sequence":"additional","affiliation":[{"name":"Division of Respiratory Medicine Center for Respiratory Diseases, National Hospital Organization Kyoto Medical Center  Kyoto Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6902-9085","authenticated-orcid":false,"given":"Kohei","family":"Fujita","sequence":"additional","affiliation":[{"name":"Division of Respiratory Medicine Center for Respiratory Diseases, National Hospital Organization Kyoto Medical Center  Kyoto Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kiminobu","family":"Tanizawa","sequence":"additional","affiliation":[{"name":"Division of Respiratory Medicine Center for Respiratory Diseases, National Hospital Organization Kyoto Medical Center  Kyoto Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,7,23]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12916\u2010024\u201003589\u20104"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1186\/s43168-025-00375-5"},{"issue":"1","key":"e_1_2_9_4_1","first-page":"1","article-title":"Understanding the Effects of Haemophilus influenzae Colonization on Bronchiectasis: A Retrospective Cohort Study","volume":"24","author":"Yang S.
