Dear Colleagues,
It is my great pleasure to welcome you to the World Conference on Infectious Diseases (WCID-2026), taking place from March 12–14, 2026, in the magnificent city of Paris, France, with hybrid access available for participants worldwide.
WCID-2026 serves as a premier international platform bringing together leading scientists, clinicians, researchers, public health professionals, and industry experts to discuss the latest advances, challenges, and innovations in infectious diseases. The conference will feature plenary and keynote lectures, oral and poster presentations, and interactive scientific discussions, fostering meaningful collaboration across disciplines and borders.
As the field of infectious diseases continues to evolve rapidly, evidence-based research, methodological rigor, and global cooperation are more critical than ever. This conference aims to promote high-quality science, encourage transparent and reproducible research, and translate scientific findings into impactful public health and clinical practice.
Whether you join us in person in Paris or participate virtually, I warmly invite you to share your research, exchange ideas, and engage with the global infectious diseases community. Your participation will be essential in shaping future directions in research, policy, and patient care.
I look forward to welcoming you to WCID-2026 and to an inspiring and successful scientific meeting.
Warm regards,
Prof. John P. A. Ioannidis, MD, DSc,
