Session formats

We strive for the congress sessions to be targeted to participants with different levels of experience and professional backgrounds. ECCMID 2023 will include different session formats. Here you can find a brief description for each of them. The programme will also be complemented by special sessions such as the Open Forum and other ad hoc formats.



Keynote Lectures target a broad audience. The speakers are leaders in their fields and present an excellent review of a specific topic to a broad audience (specialists and non-specialists). Topics should be such that introduce cutting edge science or “hot” topics in Clinical Microbiology or Infectious Diseases.
60’ talk (45-50’ minutes presentation + 10-15’ minutes Q&A)
1 speaker
2 chairpersons

Keynote Scientific Interviews feature two experts taking the role of role of interviewer (chairperson-moderator) and interviewee (keynote speaker) and discussing current experience and future challenges in Clinical Microbiology & Infectious Diseases. Interviewer and interviewee may be known to have a different opinion on a specific topic or to have taken different approaches to tackle a similar situation.
60’ talk (45-50’ interview + 10-15’ minutes Q&A)
1 speaker and 1 chairperson

Keynote speakers will also be invited to participate in Fireplace Sessions, closed meetings (requiring pre-registration) aiming at generating informal discussions with ESCMID trainees and early career members. The session will take place after the Keynote Lecture/Scientific Interview and will be moderated by the same chairpersons.


Scientific Symposia
These symposia convene renowned speakers from all over the world and cover a wide range of topics in the fields of clinical microbiology, infectious diseases and infection control. Symposia can give an overview over recent developments and research results, review the literature or present as pro/con debates; the latter being typically a 1-hour Symposium.
1-hour Symposium
2 talks of 25’ + 5 min Q&A each
2 speakers
2 chairpersons
2-hour Symposium
4 talks of 25’ + 5 min Q&A each
4 speakers
2 chairpersons


These sessions involve two speakers (named “Experts”) and target a smaller audience, commonly in an early morning time slot. The topics should have practical relevance. The session should allow for discussion with the experts and include the exchange of personal views, direct interaction, discussion of cases and experiences on a matter (“how best to ...” sessions).
2 speakers from two different countries delivering short talks followed by discussion and audience engagement on a common topic. No chairperson


Educational Workshops
Educational Workshops contain review talks and/or case studies that lend themselves to discussions. The goal of this format is education through interactivity. Individual talks should be complementary and cohesive within the workshop. Workshops can also involve case discussions and be interactive.
3 talks of 30’ each + 30’ final discussion
3 speakers from three different countries
2 chairpersons
In special circumstances, 3-hour Educational Workshops may be considered by the ECCMID Programme Committee.


Open Forums
Open forums are one-hour sessions that take place in Arenas where speakers discuss with the audience ideas and views on a particular issue. Typically, Open Forums feature controversies and policy-related aspects. Speakers can make use of electronic presentations, but that is not mandatory. The allocation of time to presentations and discussions is tailored for each session, depending on its specific agenda.


Pipeline corners
This session type allows small innovative pharmaceutical companies, with early-stage diagnostic or therapeutic solutions, to present their products to a wider audience. More details on Pipeline Corners will be available at a later stage here  and published in the Exhibition Guide.


Oral Sessions
Oral sessions are created by the ECCMID Programme Committee from the top-rated abstracts.
1-hour oral session
5 speakers, 12’ each (10’ presentation + 2 min Q&A)
2 chairpersons
