The Conference on Retroviruses and Opportunistic Infections (CROI) was established in 1993 to provide a forum for basic scientists and clinical investigators to present and discuss their investigations into the epidemiology and biology of human retroviruses and associated diseases. The goal of the conference is to provide a forum for researchers to translate their laboratory and clinical findings into tangible progress against the HIV pandemic.

CROI is the preeminent HIV research meeting in the world and attracts more than 4,000 HIV/AIDS research leaders from nearly 90 countries and 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 and additional reviewers for 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 are made available online via webcasts, podcasts, audio recordings, and electronic copies of abstracts, posters, and other documents. To view or download electronic materials, visit
