We present here the results of this medical evaluation performed 1\u00a0month after the infection.<\/jats:p><jats:p><jats:bold>Methods:<\/jats:bold> We retrospectively analyzed between April 2020 and February 2021 200 records of divers suspected of COVID-19 contamination. Data collected included physical examination, ECG, blood biochemistry, chest CT scan and spirometry.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> 145 PCR-positive subjects were included, representing 8.5% of the total population of French military divers. Two divers were hospitalized, one for pericarditis and the other for non-hypoxemic pneumonia. For the other 143 divers, physical examination, electrocardiogram and blood biology showed no abnormalities. However 5 divers (3.4%) had persistent subjective symptoms including fatigability, exertional dyspnea, dysesthesias and anosmia. 41 subjects (29%) had significant decreases in forced expiratory flows at 25\u201375% and 50% on spirometry (n = 20) or bilateral ground-glass opacities on chest CT scan (<jats:italic>n<\/jats:italic> = 24). Only 3 subjects were affected on both spirometry and chest CT. 45% of these abnormalities were found in subjects who were initially asymptomatic or had non-respiratory symptoms. In case of abnormalities, normalization was obtained within 3\u00a0months. The median time to return to diving was 45\u00a0days (IQR 30, 64).<\/jats:p><jats:p><jats:bold>Conclusion:<\/jats:bold> Our study confirms the need for standardized follow-up in all divers after COVID-19 infection and for maintaining a rest period before resuming diving activities.<\/jats:p>","DOI":"10.3389\/fphys.2022.1022370","type":"journal-article","created":{"date-parts":[[2022,11,11]],"date-time":"2022-11-11T06:19:07Z","timestamp":1668147547000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["Symptomatic or asymptomatic SAR-CoV-2 positive divers should be medically evaluated before returning to scuba diving"],"prefix":"10.3389","volume":"13","author":[{"given":"Jean","family":"Morin","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nicolas","family":"Vall\u00e9e","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pierre-Louis","family":"Dufresne","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sarah","family":"Rives","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Henri","family":"Lehot","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lucille","family":"Daubresse","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Romain","family":"Roffi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Arnaud","family":"Druelle","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pierre-Julien","family":"Cungi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jean-Eric","family":"Blatteau","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2022,11,11]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"171","DOI":"10.1016\/j.path.2010.04.002","article-title":"Small airways disease","volume":"3","author":"Allen","year":"2010","journal-title":"Surg.
