A total of  85 patients with confirmed H1N1 were hospitalised (56 adults and 29 children).  Patients\u2019 median age was 39 years (range 1 month\u201394years) and the mean hospital  length of stay was 12 days. Conditions promoting influenza complications were  present in 59% of patients and were mainly asthma, chronic obstructive pulmonary  disease (COPD), haematologic disorders and immunosuppressive treatment. The  most common reported symptoms were cough, fever, dyspnoea and rhinopharyngitis.  Most of the patients (n = 72, 85%) were treated by neuraminidase inhibitors,  and 44% (n = 37) received antibiotics for secondary bacterial infection.  Fourteen patients (11 adults and 3 children, 16%) developed respiratory failure  and were admitted to the intensive care unit (ICU) for respiratory monitoring  and\/or ventilatory support. The mean ICU length of stay was 11.3 days. The  mortality rate was 2.5% among all patients.\nCONCLUSIONS:Geneva\u2019s  experience of the 2009 H1N1 pandemic showed that most of the hospitalised  patients were young adults or children. Half of them presented predisposing  diseases but only 16% were admitted to the ICU. The mortality rate was  low.<\/jats:p>","DOI":"10.4414\/smw.2011.13177","type":"journal-article","created":{"date-parts":[[2011,10,27]],"date-time":"2011-10-27T03:48:08Z","timestamp":1319687288000},"page":"w13177","source":"Crossref","is-referenced-by-count":4,"title":["Clinical  features and outcomes of hospitalised adults and\u00a0children with the 2009  influenza A H1N1 infection at\u00a0Geneva\u2019s University Hospital"],"prefix":"10.57187","volume":"141","author":[{"given":"A","family":"Iten","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"N","family":"Wagner","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M","family":"Descombes","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"V","family":"Camus","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"L","family":"Kaiser","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M","family":"Louis-Simonet","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"LM","family":"L\u00fccker","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"36756","published-online":{"date-parts":[[2011,3,14]]},"container-title":["Swiss Medical Weekly"],"original-title":[],"link":[{"URL":"https:\/\/smw.ch\/index.php\/smw\/article\/download\/1264\/1412","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/smw.ch\/index.php\/smw\/article\/download\/1264\/1413","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/smw.ch\/index.php\/smw\/article\/download\/1264\/1412","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,15]],"date-time":"2025-08-15T02:47:51Z","timestamp":1755226071000},"score":1,"resource":{"primary":{"URL":"https:\/\/smw.ch\/index.php\/smw\/article\/view\/1264"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2011,3,14]]},"references-count":0,"journal-issue":{"issue":"1112","published-online":{"date-parts":[[2011,3,14]]}},"URL":"https:\/\/doi.org\/10.4414\/smw.2011.13177","relation":{},"ISSN":["1424-3997"],"issn-type":[{"value":"1424-3997","type":"electronic"}],"subject":[],"published":{"date-parts":[[2011,3,14]]}}}
