  • Check abstract thoroughly for spelling and grammar.
  • Do not include references.
  • Abstract presenters who are not scholarship recipients will be required to fund in full their own attendance at the Congress (including Congress registration and travel expenses) and should not accept to present an abstract if this is not possible.
  • All accepted and presented abstracts will be published in an international journal prior to the Congress.
  • Please indicate at the time of abstract submission if you wish to apply for a scholarship. Please see the scholarship information page for further details.

Disclosure of Interest

ISSTDR and IUSTI recognize the considerable contribution that industry partners make for professional and research activities. We also recognize the need for transparency and the disclosure of potential conflicts of interest by acknowledging these relationships in publications and presentations.

The abstract submitter and presenting author will each need to provide disclosure information. This statement will not count towards the 300 word limit. If your abstract is accepted, you will be requested to include a Disclosure of Interest statement in your oral or poster presentation. 

By submitting an abstract, all authors agree to release the license to the Congress organizers and give permission to publish the abstract in the Congress handbook and on the website (and by doing so, certify that the abstract is original work).

Late Breaking Abstracts

The Congress organizers are interested in attracting the latest and strongest scientific findings in STI and HIV research. You are invited to submit a Late Breaking Abstract reporting on your research in the format specified in the Late Breaking guidelines.

Late Breaking Abstract Submission Guidelines: Please follow the Abstract Submission Guidelines outlined above.

Selection Criteria:

  • Late Breaking Abstracts must present original data of the highest methodological standards. For example, for a clinical or epidemiology presentation, the main results of a randomized controlled trial or large observational study would be eligible for consideration.
  • The topic of the research should be of the strongest interest to the Congress delegates.
  • The body of the abstract must clearly indicate that data collection for the research was still underway in 2019 or late 2018, if a complex analysis was required.
  • Abstracts that do not explicitly meet these requirements will not be sent for review.

Late Breaking Abstract Submission Deadline: March 22, 2019 (23:59 PST).

Please note: Late breaking abstract presenters will be required to fund in full their own attendance at the Congress (including Congress registration and travel expenses) and should not submit a late breaking abstract if this is not possible.  No scholarships are available for late breaker abstract presentations.

Final selection of Late Breaking Abstracts will be done by members of the International Scientific Program Committee and notification of acceptance or non acceptance of abstracts will be sent to the submitting author by April 5, 2019.
