We discovered a security incident on our website and have temporarily taken the website offline as a precaution while we investigate and arrange safe restoration. This affects access to conference Video on Demand sessions and the Patient Recap livestream recording, and delays the first access instructions for in-person conference attendees. We are preparing direct notifications for potentially affected website users. Whether personal information was accessed or copied remains under investigation. We understand the concern and inconvenience. We cannot yet confirm a restoration date, but will share updates as the work progresses. For questions, please contact secretariat@islc-pais.org. Thank you for your patience and understanding.

Fascinating work. The ability to combine whole-body 3D imaging with single-cell transcriptomics opens up some very exciting possibilities for #LongCOVID and #PAIS #research. @DaniBeckman, any chance your talented friend @HarsharanBhatia is available for a trip to Amsterdam next August? Asking for a conference organizer… 😉🇳🇱

To help support attendees travelling to #Amsterdam for the ISLC-PAIS Conference 2026, @airfrance and @KLM Royal Dutch Airlines are offering discounted fares for eligible participants attending the conference. As an independent international non-profit conference, we know that travel costs can be a barrier, especially for researchers, clinicians and early-career professionals travelling internationally. We hope this helps make participation a little more accessible. More information on how to access the travel discount will be shared with registered attendees by email next week. islc-pais.org

ABSTRACT DEADLINE EXTENDED! Over the past weeks, we have received over 125 highly interesting submissions across biomedical, clinical and impact-focused research related to #LongCOVID and Post-Acute Infection Syndromes (#PAIS) for the ISLC-PAIS Conference 2026 (26-29 August) in Amsterdam. At the same time, we have received multiple requests from researchers and interdisciplinary teams asking whether submissions could still be accepted due to ongoing analyses, internal review processes and timing constraints. As an independent non-profit initiative focused on strengthening international collaboration and accelerating real-world impact, we want to make participation possible for as many relevant contributions as we can. Because more knowledge leads to better outcomes, we have decided to extend the abstract submission deadline until: 📅 28 May 2026 We welcome submissions from researchers, clinicians, healthcare professionals and experts from related disciplines. Early-career researchers are especially encouraged to contribute. Accepted abstracts will be considered for: • oral presentations • poster sessions • panel discussions If you are working on #LongCOVID, #MECFS or related #PAIS conditions, we warmly encourage you to submit your work and help shape the international conversation in Amsterdam. 👉 Abstract Submission - lnkd.in/e5gMriXZ We are also very grateful to the members of our International Abstract Committee for helping shape the scientific quality and interdisciplinary scope of the conference, including #DannyAltmann | @DaniBeckman | @surf4children | @jencurtinmd | @Sunny_Rae1 | @AndrewEwing11 | @DrMark_Faghy | @drMHellemons | @DavidJoffe64 | @PutrinoLab | @satish_r_raj | @resiapretorius | #IleneRuhoy. #MedicalResearch #ScientificConference #CallForAbstracts #ClinicalResearch #Immunology #ISLCPAIS2026

A memorable moment during today’s ISLC-PAIS Conference organizing call: our Foundation Chairman @RobWust received the news that his new #LongCOVID/#PAIS research project has officially been awarded funding by @ZonMw . Especially important: the project will also include severely affected homebound and bedbound patients a group still far too often underrepresented in research. Huge congratulations to Rob and his team on this well-deserved recognition. Their recent appearance on Dutch national television once again showed the passion, dedication and scientific curiosity that continue to drive this important work forward. We are so proud to have him as our chairman and the scientific host of the conference. #LongCOVID #PAIS #MECFS #MedicalResearch
