Abstracts were invited across three interconnected tracks: Biomedical, Clinical, and Impact, covering biological mechanisms, clinical research, lived experience, healthcare systems and the wider implications of PAIS.

How are abstracts presented?

Accepted abstracts have been considered for oral presentations, poster sessions, or panel discussions, depending on scientific relevance and overall program balance.

What were the 2026 key dates?

Late-Breaking Poster Abstract submission is now closed

Thank you to everyone who submitted a late-breaking poster abstract for the 2026 Amsterdam ISLC-PAIS Conference. This final submission round was intended for important new findings that were not available before the regular abstract deadline. The submission and review schedule described on this page relates to the completed 2026 edition. No further submissions are being accepted.

To support a clear and fair review process, abstracts are expected to be written in professional English and should clearly describe the purpose, approach and key findings or insights.

For practice-based and impact-oriented submissions, these elements may be adapted to reflect the nature of the work, such as implementation experience, policy relevance, or societal impact. Abstracts should describe completed or sufficiently developed work at the time of submission. Submissions are expected to include substantive findings or insights, rather than statements of intent.

When referring to patients or populations, authors are kindly encouraged to use person-first language (for example, “people with Long COVID” rather than condition-first terms).

The 2026 ISLC-PAIS Conference welcomed abstract submissions contributing to a better understanding of Long COVID and other Post-Acute Infection Syndromes (PAIS). The call included original research, clinical insights, practice-based evidence, and societal, policy, healthcare system and lived-experience perspectives. Interdisciplinary contributions and submissions from early-career researchers and professionals were encouraged. The 2026 submission process is closed.

Abstracts must be submitted electronically via the online submission system before the stated deadline 30 May 2026. All required fields in the submission form must be completed before final submission. Submissions by email are not accepted. A single optional figure may be included in the uploaded abstract file for illustrative purposes. Tables and multiple figures are not permitted. The abstract text remains the primary basis for review.

It is the responsibility of the submitting author (primary contact) to ensure that all co-authors approve the submission and are informed of the abstract’s status.

Abstracts that are incomplete or not formally submitted before the deadline cannot be reviewed.

Accepted abstracts will be included in the official conference abstract book and may be made publicly available via the ISLC-PAIS website after the conference. By submitting an abstract, authors agree that their submission will be reviewed for conference and program purposes only, in accordance with applicable data protection regulations.

The 2026 review process was based on scientific relevance, clarity, alignment with the conference tracks and overall program balance. Review was assigned to the International Abstract Committee, with final scheduling and session placement assigned to the Scientific Program Committee. The dates and procedures described on this page relate to the completed 2026 edition; no review or notification round is currently pending.

We are grateful to our distinguished international experts who generously contribute their time and expertise to ensure a rigorous and fair review process.
