CONFERENCE EMBARGO POLICY

All E-Poster abstracts are embargoed until 18 November 13:00 CET.

All abstracts are embargoed until the time and date of the start of the session (oral abstract or short oral abstract session) in which they are delivered or during a press conference – whichever comes first.

CONFLICT OF INTEREST

Please note that all presenters are required to include their COI by the time they upload their presentation and inform about it at the start of their oral presentation.

E-Poster presenters will need to upload their COI before being able to upload their poster presentation.

Presentation Format

General Information

  • Updates may be shared during the presentation, but no modifications can be made to the submitted abstract.
  • If you are not able to upload your presentation by the stated deadline of 14 November, notify the corresponding programme as soon as possible:
  • It is strictly forbidden to present abstracts whose content is to be published or publicly presented before presentation at The Union World Conference. Please read the above-mentioned Conference Embargo Policy.
  • The Union is committed to promoting person-centred, non-stigmatising language in all materials and therefore requests that authors follow the guidelines laid out in the Stop TB Partnership’s publication, Words Matter Language Guide | Stop TB Partnership.

As a speaker, you are invited to upload your presentation on the online platform by the stipulated deadline shown on the invitation email that you will receive from support@openslideservices.com. You will also have to check and validate your presentation at the Speaker Service Centre before the beginning of your session. Details about the location and opening hours will be provided at a later stage.

The online platform will make it quick and easy for speakers to upload their Power Point presentations prior to conference. We strongly recommend all speakers take advantage of this option.

For organisational purposes, we invite you to visit the Speaker Service Centre at least two hours before the starting time of your session. A dedicated team of technicians will assist you with verifying your presentation.

To allow each speaker enough time to check their presentation, only minor modifications are allowed on the working stations at the Speaker Service Centre.

Presentation format

All presentations should be in PowerPoint format and PC compatible.

PowerPoint 2019 and previous versions are accepted.

Save your file with a .pptx extension for a better compatibility.

Media elements:

  • Use the ‘Insert’ function to integrate media elements, such as  images and video
  • Try to limit the size of your videos and sound to 1GB and use formats such as .mp4 and .wmv if possible.
  • If your video files come from a medical equipment, make sure you do not need a special proprietary software to play it on a PC.

If you work on a Mac try to avoid specific fonts in Mac OS and rather choose Windows compatible fonts.

You should bring a copy of your presentation, including a copy of your video file(s), on a USB flash drive or an external hard drive, in case required while checking your presentation at the speaker centre on site.

There is no option to load your presentation in the session room using a USB drive, or to connect your personal laptop.  All presentations will be run from the PC provided in the session room.

Information for Chairs

If you are chairing a session at this year’s conference, we encourage you to use the Q&A tool within the conference app to manage audience interactions. This is especially important this year, as public health funding cuts mean that many participants will only be able to join online. 


A short video tutorial is available to guide you on how to open and manage audience questions during your session.


The Chair Tool can be easily accessed through the iPad provided in each session room. Each iPad will also include a quick reference guide, and programme staff and/or volunteers will be available to assist you if needed.
