Despite the high volume of outbound travel from Australia, peaking at 10.8 million travellers in 2023, limited data exist on the burden of overseas-acquired STIs. This study aims to investigate the burden and trends of overseas- and locally acquired STIs in Australia.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We analysed STI cases notified to Australia\u2019s National Notifiable Diseases Surveillance System (NNDSS) from January 2017 to December 2023. A comparative analysis was conducted by place of acquisition (i.e. overseas versus local), with the geographical origins of overseas-acquired cases mapped using ArcMap and temporal trends assessed across pre-COVID-19, pandemic and post-pandemic periods.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>A total of 967\u2009193 records were obtained from NNDSS, of which 188\u2009788 STI cases (11\u2009782 overseas- and 177\u2009006 locally acquired) were included in the analysis. Males were the most affected group (63% of overseas- and 60% of locally acquired), and young adults aged 20\u201324\u00a0years represented a quarter of cases (24.6% of overseas- and 25.9% of locally acquired). The incidence of overseas-acquired STI cases rose nearly threefold, from 12.8 per 100\u2009000 travellers in 2017 to 35.0 per 100\u200900 travellers in 2019, and then declined during the COVID-19 pandemic due to Australia\u2019s travel restrictions to 16.4 per 100\u2009000 travellers in 2020. A surge was observed in 2021, with 46.5 per 100\u2009000 travellers. The most common regions of acquisition were Southeast Asia (n\u2009=\u20092390, 44.6%), North and South America (n\u2009=\u2009663, 12.4%) and Northwest Europe (n\u2009=\u2009580, 10.8%).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This study highlights the patterns of overseas- and locally acquired STIs in Australia, with chlamydia remaining the most prevalent (but declining since 2021), while gonorrhoea has been increasing, among overseas-acquired cases. Variations in the region of acquisition and demographic factors highlight the critical need for tailored safer-sex advice during pre-travel consultations, particularly for males and young adults travelling to high-prevalence destinations.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1093\/jtm\/taaf022","type":"journal-article","created":{"date-parts":[[2025,3,2]],"date-time":"2025-03-02T23:15:25Z","timestamp":1740957325000},"source":"Crossref","is-referenced-by-count":4,"title":["Overseas- and locally acquired sexually transmissible infections in Australia, 2017\u201323"],"prefix":"10.1093","volume":"32","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4348-591X","authenticated-orcid":false,"given":"Wondimeneh","family":"Shiferaw","sequence":"first","affiliation":[{"name":"UQ Centre for Clinical Research&gt;, Faculty of Health, Medicine and Behavioural Sciences, The University of Queensland , Herston , Queensland (QLD),","place":["Australia"]},{"name":"Asrat Woldeyes Health Science Campus, Debre Berhan University , Debre Berhan,","place":["Ethiopia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Judith A","family":"Dean","sequence":"additional","affiliation":[{"name":"School of Public Health, Faculty of Health, Medicine and Behavioural Sciences, The University of Queensland , Herston , Queensland (QLD),","place":["Australia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Deborah","family":"Mills","sequence":"additional","affiliation":[{"name":"UQ Centre for Clinical Research, Faculty of Health, Medicine and Behavioural Sciences, The University of Queensland , Herston , Queensland (QLD),","place":["Australia"]},{"name":"Dr Deb the Travel Doctor, Travel Medicine Alliance , Brisbane , Queensland (QLD),","place":["Australia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Colleen L","family":"Lau","sequence":"additional","affiliation":[{"name":"UQ Centre for Clinical Research, Faculty of Health, Medicine and Behavioural Sciences, The University of Queensland , Herston , Queensland (QLD),","place":["Australia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luis","family":"Furuya-Kanamori","sequence":"additional","affiliation":[{"name":"UQ Centre for Clinical Research, Faculty of Health, Medicine and Behavioural Sciences, The University of Queensland , Herston , Queensland (QLD),","place":["Australia"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2025,3,5]]},"reference":[{"key":"2025050302111285900_ref1","volume-title":"Global Health Sector Strategies on, Respectively, HIV, Viral Hepatitis and Sexually Transmitted Infections for the Period 2022\u20132030","year":"2022"},{"key":"2025050302111285900_ref2","doi-asserted-by":"crossref","first-page":"851635","DOI":"10.3389\/fmed.2022.851635","article-title":"Incidence trends of five common sexually transmitted infections excluding HIV from 1990 to 2019 at the global, regional, and national levels: Results from the global burden of disease study 2019","volume":"9","author":"Fu","year":"2022","journal-title":"Front Med"},{"key":"2025050302111285900_ref3","first-page":"265","article-title":"Why risk matters for STI control: Who are those at greatest risk and how are they identified?","volume":"19","author":"Traeger","year":"2022","journal-title":"Sex Health"},{"key":"2025050302111285900_ref4","doi-asserted-by":"publisher","author":"King","DOI":"10.26190\/f5ph-f972"},{"key":"2025050302111285900_ref5","first-page":"ofad017","article-title":"Incidence and risk factors for early syphilis among men who have sex with men in Australia, 2013-2019: A retrospective cohort study.
