Abstract Submission

Late breaker abstracts are welcome at IUSTI 2026. They are expected to contain results of exceptional value that will significantly change current practice. There should be good reasons why the results could not have been presented in time for the regular abstract cut off date: for example closing date for trial recruitment is after standard date. Late breaker abstract submissions will be subject to the same level of peer review as standard abstracts but with rejection likely where these criteria are not met.

We cannot guarantee that Late Breaker abstracts will be published in the Congress proceedings but will make every effort to do so. We have reserved specific oral presentation time for selected Late Breaker abstracts. Please note that the late breaker abstracts are not eligible for the awards.

Late Breaker Submission Opens: Monday 6 July 2026 

Late Breaker Submission Closes: Tuesday 11 August 2026

Late Breaker Notification: early September 2026

IUSTI 2026 World Meeting Scholarships and Awards

A range of awards will be presented at the IUSTI 2026 World Congress to recognize outstanding scientific contributions. Some awards will be restricted by geographic region or career stage, while others will provide financial support to attend the 2026 World Congress. Awards are primarily based on the quality of the submitted abstract, with some also considering excellence in presentation during the congress. Please answer the following eligibility questions to be considered for these awards. The Congress Scholarship Committee reserves the right to request additional documentation for verification. All decisions of the Scholarship Committee Chair are final.

The Elwyn Hopkin Scholarship was established in memory of Elwyn E Hopkin to support the participation of outstanding early-career researchers from low- and middle-income countries attending the International Union Against Sexually Transmitted Infections World Congresses. The scholarship is awarded to a graduate student or postdoctoral fellow who is attending the Congress in person, has submitted a highly ranked abstract, and has been selected to deliver an oral presentation. In 2026 the value will be £1000.
