The risk of developing symptoms of the post-COVID-19 condition is higher in women infected during pregnancy than in non-obstetric cohorts.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Method<\/jats:title>\n                    <jats:p>We conducted a nationwide, prospective, population-based cohort study based on questionnaire data investigating the extent of post-COVID-19 condition after SARS-CoV-2 infection during pregnancy and whether the condition was related to the trimester at infection or the severity of infection. All women with a positive SARS-CoV-2 test during pregnancy in Denmark between 1 March 2020 and 17 November 2021 were invited to participate by responding to an online questionnaire.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Result<\/jats:title>\n                    <jats:p>Overall, 2,406 women met our inclusion criteria and were invited to participate by receiving an online questionnaire. In total, 1,007 (41.9%) responded to the survey, and 920 (38.2%) completed \u226570% of the items in the questionnaire and were included in the analysis. In total, 636 (69.1%) experienced a symptom of post-COVID-19 condition at any given time after SARS-CoV-2 infection, and 465 (50.1%) had at least one symptom of post-COVID-19 condition lasting \u22658\u202fweeks after primary infection with SARS-CoV-2. The most common symptoms were fatigue, a change in the sense of smell and taste, and hair loss. The onset of most symptoms was within the first 4\u202fweeks after infection with SARS-CoV-2. The median duration of symptoms differed substantially, ranging from 4 to 40\u202fweeks, with forgetfulness lasting the longest. Participants who experienced symptoms during their primary SARS-CoV-2 infection were more likely to report symptoms of post-COVID-19 condition. However, we found no association between disease severity or trimester of infection and subsequent post-COVID-19 condition.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Half of the women with SARS-CoV-2 infection during pregnancy had symptoms of post-COVID-19 condition lasting \u22658\u202fweeks. The likelihood of reporting symptoms of post-COVID-19 condition increased when having symptomatic SARS-CoV-2 infection during pregnancy. Nonetheless, we found no association between severe disease requiring hospital admission or the trimester of infection and the subsequent development of post-COVID-19 condition.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fmed.2025.1674554","type":"journal-article","created":{"date-parts":[[2026,1,21]],"date-time":"2026-01-21T06:52:27Z","timestamp":1768978347000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Post-COVID-19 condition after SARS-CoV-2 infection during pregnancy: a population-based questionnaire cohort study"],"prefix":"10.3389","volume":"12","author":[{"given":"Cecilie B\u00f8ge","family":"Paulsen","sequence":"first","affiliation":[{"name":"Department of Anesthesiology, Copenhagen University Hospital \u2013 Hvidovre-Amager","place":["Copenhagen, Denmark"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cecilie","family":"Isgaard","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Copenhagen University Hospital \u2013 Holb\u00e6k","place":["Holb\u00e6k, Denmark"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lone","family":"Krebs","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Copenhagen University Hospital \u2013 Hvidovre-Amager","place":["Copenhagen, Denmark"]},{"name":"Department of Clinical Medicine, University of Copenhagen","place":["Copenhagen, Denmark"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anna J.
