When the COVID-19 pandemic hit Switzerland in 2020, the government implemented hygiene measures for the general population. We investigated the impact of these measures on the transmission of CARV in lung transplant recipients in Switzerland. Materials and Methods: In this multicenter, retrospective study of lung transplant recipients, we investigated two time periods: the year before the COVID-19 pandemic (1 March 2019\u201329 February 2020) and the first year of the pandemic (1 March 2020\u201328 February 2021). Data were mainly collected from the Swiss Transplant Cohort Study (STCS) database. Descriptive statistics were used to analyze the results. Results: Data from 221 Swiss lung transplant cohort patients were evaluated. In the year before the COVID-19 pandemic, 157 infections were diagnosed compared to 71 infections in the first year of the pandemic (decline of 54%, p &lt; 0.001). Influenza virus infections alone showed a remarkable decrease from 17 infections before COVID-19 to 2 infections after the beginning of the pandemic. No significant difference was found in testing behavior; 803 vs. 925 tests were obtained by two of the three centers during the respective periods. Conclusions: We observed a significant decline in CARV infections in the Swiss lung transplant cohort during the first year of the COVID-19 pandemic. These results suggest a relevant impact of hygiene measures when implemented in the population due to the COVID-19 pandemic on the incidence of CARV infections.<\/jats:p>","DOI":"10.3390\/medicina59081473","type":"journal-article","created":{"date-parts":[[2023,8,16]],"date-time":"2023-08-16T10:17:52Z","timestamp":1692181072000},"page":"1473","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Impact of SARS-CoV-2-Related Hygiene Measures on Community-Acquired Respiratory Virus Infections in Lung Transplant Recipients in Switzerland"],"prefix":"10.3390","volume":"59","author":[{"given":"Isabelle","family":"Baumann","sequence":"first","affiliation":[{"name":"Faculty of Medicine, University of Zurich, 8032 Zurich, Switzerland"},{"name":"Division of Pulmonology, University Hospital Zurich, 8091 Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1994-7443","authenticated-orcid":false,"given":"Ren\u00e9","family":"Hage","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, University of Zurich, 8032 Zurich, Switzerland"},{"name":"Division of Pulmonology, University Hospital Zurich, 8091 Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paola","family":"Gasche-Soccal","sequence":"additional","affiliation":[{"name":"Division of Pulmonology, University Hospitals Geneva, 1205 Geneva, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8856-4000","authenticated-orcid":false,"given":"John-David","family":"Aubert","sequence":"additional","affiliation":[{"name":"Division of Pulmonology, University Hospital Lausanne, 1011 Lausanne, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5404-7566","authenticated-orcid":false,"given":"Mac\u00e9 M.","family":"Schuurmans","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, University of Zurich, 8032 Zurich, Switzerland"},{"name":"Division of Pulmonology, University Hospital Zurich, 8091 Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"The Swiss Transplant Cohort Study","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,8,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"32","DOI":"10.1136\/thoraxjnl-2013-203581","article-title":"Incidence and outcomes of respiratory viral infections in lung transplant recipients: A prospective study","volume":"69","author":"Bridevaux","year":"2014","journal-title":"Thorax"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"399","DOI":"10.1136\/thx.2008.105155","article-title":"Respiratory viruses in bronchoalveolar lavage: A hospital-based cohort study in adults","volume":"64","author":"Garbino","year":"2009","journal-title":"Thorax"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"1071","DOI":"10.1111\/j.1600-6143.2011.03490.x","article-title":"Respiratory Viruses in Lung Transplant Recipients: A Critical Review and Pooled Analysis of Clinical Studies","volume":"11","author":"Vu","year":"2011","journal-title":"Am.
