What is 21st International Congress on Infectious Diseases?
On behalf of the International Society for Infectious Diseases (ISID), it is our distinct honor to invite you to the 21st International Congress on Infectious Diseases (ICID 2026), which will be held in Madrid, Spain, from November 10–13, 2026.
Since its inception more than two decades ago, the ICID has served as a globally recognized platform for advancing science, clinical practice, and public health policy in the field of infectious diseases. Each congress has marked new milestones, whether unveiling pivotal research outcomes, informing pandemic preparedness, or fostering the next generation of leaders in global health. Building on this legacy, ICID 2026 promises to be a landmark event that both reflects on transformative progress and looks ahead to emerging challenges.
The scientific programme will feature plenary lectures from internationally renowned experts, in-depth symposia, interactive workshops, and state-of-the-art poster sessions, designed to highlight the latest breakthroughs in microbial pathogenesis, vaccine development, antimicrobial resistance, zoonotic and emerging infections, digital health innovations, and strategies to advance health equity worldwide.
By bringing together scientists, clinicians, epidemiologists, policymakers, and community stakeholders, ICID 2026 in Madrid is designed to spark collaborations that turn research into practical, global health solutions, set within a city whose vibrant cultural heritage and history of scientific exchange reflect the energy and diversity of our field. This Congress provides a vital forum for all attendees from seasoned investigators and public health leaders to veterinarians, industry partners, and early-career professionals to share knowledge, forge partnerships, and collectively guide the future of infectious disease prevention and care.
We look forward with great anticipation to welcoming you to Madrid for what promises to be an unforgettable and transformative gathering of the infectious disease community.
