This study examined the seroprevalence of Chlamydia trachomatis, Mycoplasma genitalium, herpes simplex virus (HSV) types 1 and 2, and several human papillomaviruses (HPV) in the Swedish population over time.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>The study population consisted of 30-year-old women attending maternity care, and 50\u00a0year-old men and women attending health check-ups, from 1975 to 2018.

Of these, 41.5% showed seropositivity for Chlamydia trachomatis, 16.7% for Mycoplasma genitalium, 70.5% for HSV-1, 14.9% for HSV-2, 13.2% for high-risk HPV, and 8.3% for low-risk HPV. Seropositivity for Mycoplasma genitalium, HSV-1 and especially Chlamydia trachomatis decreased over time.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>There was a decrease over time in Chlamydia trachomatis seroprevalence, probably due to contact tracing, testing and early treatment; this might also have affected Mycoplasma genitalium seroprevalence. Despite the reduction, seroprevalences are still high, so continued and new efforts to reduce STI incidence are essential.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/09564624241248874","type":"journal-article","created":{"date-parts":[[2024,4,25]],"date-time":"2024-04-25T02:37:23Z","timestamp":1714012643000},"page":"696-702","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Seroprevalence of sexually transmitted infections over 44 years \u2013 A cross-sectional study in Sweden"],"prefix":"10.1177","volume":"35","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7682-4565","authenticated-orcid":false,"given":"Nirina","family":"Andersson","sequence":"first","affiliation":[{"name":"Department of Public Health and Clinical Medicine, Dermatology and Venereology, Ume\u00e5 University, Ume\u00e5, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tim","family":"Waterboer","sequence":"additional","affiliation":[{"name":"Infections and Cancer Epidemiology, German Cancer Research Center (Deutsches Krebsforschungszentrum [DKFZ]), Heidelberg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elisabet","family":"Nylander","sequence":"additional","affiliation":[{"name":"Department of Public Health and Clinical Medicine, Dermatology and Venereology, Ume\u00e5 University, Ume\u00e5, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7865-4560","authenticated-orcid":false,"given":"Annika","family":"Idahl","sequence":"additional","affiliation":[{"name":"Department of Clinical Sciences, Obstetrics and Gynecology, Ume\u00e5 University, Ume\u00e5, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2024,4,24]]},"reference":[{"key":"bibr1-09564624241248874","doi-asserted-by":"publisher","DOI":"10.1093\/infdis\/jiad047"},{"key":"bibr2-09564624241248874","doi-asserted-by":"publisher","DOI":"10.1186\/s12978-022-01403-z"},{"key":"bibr3-09564624241248874","doi-asserted-by":"publisher","DOI":"10.1097\/OLQ.0000000000001380"},{"key":"bibr4-09564624241248874","doi-asserted-by":"publisher","DOI":"10.1001\/jama.2021.23487"},{"key":"bibr5-09564624241248874","doi-asserted-by":"publisher","DOI":"10.1097\/00007435-200102000-00009"},{"key":"bibr6-09564624241248874","unstructured":"The public health agency of Sweden - disease statistics.
