Recurrent aspiration of sediment\u2010rich river water can lead to chronic inflammatory lung injury with possible environmental pathogen colonization and destructive lung disease, even in immunocompetent individuals. A 35\u2010year\u2010old non\u2010smoking professional diver in a tropical mangrove region of the Sundarban, Bangladesh, with 17\u2009years of exposure performing 10\u201315 daily dives in muddy saline mangrove water, presented with 1\u2009year of progressive exertional dyspnea and intermittent cough. Water aspiration during mud collection was frequent; four coworkers reported similar symptoms. SpO\n                    <jats:sub>2<\/jats:sub>\n                    was 93% at rest, dropping to 89% after 700\u2009m on a 6\u2010min walk test, indicating exercise\u2010induced desaturation despite preserved walking distance. Digital clubbing and bilateral coarse crepitations were present. HRCT showed diffuse nodules and a left upper lobe cavitary lesion; Mantoux and Interferon gamma release assay were negative. Pulmonary function revealed severe restrictive defect (TLC 39%, FVC 25%, DLCO 36%, RV\/TLC 48%). BAL grew\n                    <jats:italic>Acinetobacter<\/jats:italic>\n                    sensitive to meropenem and amikacin. After 7\u2009days of IV therapy, symptoms improved, but domiciliary oxygen was not feasible. The patient died 1\u2009month later. Muddy water pneumonitis can cause progressive necrotizing lung injury in divers, likely representing a multifactorial process involving environmental particulate exposure with superimposed infection. It was worsened by socioeconomic constraints and highlights the need for occupational protection and early recognition.\n                  <\/jats:p>","DOI":"10.1002\/rcr2.70697","type":"journal-article","created":{"date-parts":[[2026,7,30]],"date-time":"2026-07-30T04:06:08Z","timestamp":1785384368000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Muddy Water Pneumonitis: An Emerging Occupational Lung Disease in Professional Divers"],"prefix":"10.1002","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8979-2256","authenticated-orcid":false,"given":"Sadia Sultana","family":"Resma","sequence":"first","affiliation":[{"name":"Department of Respiratory Medicine National Institute of Diseases of the Chest and Hospital  Dhaka Bangladesh"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dewan Azmal","family":"Hussain","sequence":"additional","affiliation":[{"name":"Department of Respiratory Medicine National Institute of Diseases of the Chest and Hospital  Dhaka Bangladesh"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rashedul Hasan","family":"Ripon","sequence":"additional","affiliation":[{"name":"Department of Respiratory Medicine National Institute of Diseases of the Chest and Hospital  Dhaka Bangladesh"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-3987-078X","authenticated-orcid":false,"given":"Fazle","family":"Rabbi","sequence":"additional","affiliation":[{"name":"Department of Respiratory Medicine National Institute of Diseases of the Chest and Hospital  Dhaka Bangladesh"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,7,29]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.diagmicrobio.2016.10.014"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1586\/14787210.2015.1025055"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1136\/thorax-2024-222306"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12879-017-2589-0"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1164\/ajrccm.166.1.at1102"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1183\/09031936.00150314"}],"container-title":["Respirology Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/rcr2.70697","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1002\/rcr2.70697","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/rcr2.70697","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,27]],"date-time":"2026-08-27T03:23:38Z","timestamp":1787801018000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/rcr2.70697"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,7,29]]},"references-count":6,"journal-issue":{"issue":"8","published-print":{"date-parts":[[2026,8]]}},"alternative-id":["10.1002\/rcr2.70697"],"URL":"https:\/\/doi.org\/10.1002\/rcr2.70697","archive":["Portico"],"relation":{},"ISSN":["2051-3380","2051-3380"],"issn-type":[{"value":"2051-3380","type":"print"},{"value":"2051-3380","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,7,29]]},"assertion":[{"value":"2026-04-03","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-07-03","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-07-29","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"e70697"}}
