IUMS 2026, the 19th Congress of the International Union of Microbiological Societies, returns to Lisbon, Portugal from 4 November 2026 to 6 November 2026, bringing the congress community together. Bringing together professionals, researchers and decision-makers, it has become an important meeting point for the field. As a biennial event, it gives the community a regular moment to come together. Organisers expect close to 1400 attendees, from first-time visitors to seasoned professionals. Doors open at Lisbon Exhibition and Congress Centre, a space designed to keep large gatherings flowing smoothly.

Hosting IUMS 2026 in Lisbon is part of the draw. Lisbon pairs world-class event infrastructure with the kind of energy that makes a business trip worthwhile. Whether you fly in or come by rail, Lisbon is well served and easy to move around. Rooms near the venue go quickly around the dates, but the wider city offers plenty of alternatives within easy reach. Leave a little time to explore: Lisbon's dining, culture and attractions make the trip about more than just the event.

The agenda spans Microbiology, Clinical Microbiology, Bacteriology, Virology, Mycology and Health Care, with something for both newcomers and seasoned professionals. Roundtables, masterclasses and Q&A sessions round out the experience. Meeting the right people is half the point, and the schedule is built to make that happen. Kenes Group handles the organising, and the seamless run of the days is the proof.

Expect to leave informed, inspired and better connected than when you arrived. IUMS 2026 has become a dependable highlight for experts, buyers and partners from around the world, and this edition looks no different.

A little planning goes a long way here: map out the sessions or stands you cannot miss before you arrive.
