Welcome to the 21st Workshop website!


Workshop's mission
The objective of this conference is to bring together junior and senior researchers from both developed and developing countries working on cohorts of patients with HIV or hepatitis to present in an informal format their latest findings and work in progress and allow open discussions on common issues of cohort methodology, techniques and statistics. This conference aims at pursuing new findings or analyses and facilitating scientific debates of methods, results, and clinical and epidemiological implications of the HIV epidemic in Europe and elsewhere in the world. We are once again aiming to include attendees representing cohort studies from all regions. As in the past, we encourage discussion of work in progress, so all data presented will not be publicised outside of the Workshop, this includes the programme not being distributed prior to or after the meeting.
