General Information

The annual Conference on Retroviruses and Opportunistic Infections (CROI) brings together top scientists from around the world to share with each other, with clinicians, and with policy makers the latest studies, important developments, and best methods in the ongoing battle against HIV/AIDS and related infectious diseases. CROI is a global model of collaborative science and the premier international venue for refining clinical practice from research results.

Exemplifying the extraordinary scale of CROI, the registered attendees often number 4000 from more than 87 countries. Nearly half of CROI attendees come from outside the United States.  In recent years, more than 1000 abstracts have been selected for presentation at CROI.

Abstracts are evaluated by the Scientific Program Committee for, among other criteria, the relevance of their topics, the rigor of their research, and the distinct contributions they make to the broad spectrum of study that CROI strives to provide each year. For more information on preparing abstracts, submitting them electronically, and submission deadlines, visit the Abstract Guidelines page.

Attendance at the conference is open to researchers and clinical educators actively involved in the study and management of HIV, other retroviruses, and related medical conditions. For registration information, visit: the Conference Registration page. Limited space is also available to members of the media whose work aligns with the scientific and educational aims of the conference. Media professionals interested in attending can find application and registration materials in the Conference Registration page

During and after CROI, most of the presentations and material shared will be made available online via webcasts, podcasts, audio recordings, and electronic copies of abstracts, posters, and other documents. To view or download electronic materials, visit
