The 33rd Conference on Retroviruses and Opportunistic Infections (CROI) is an annual scientific meeting held in Denver, Colorado, USA, at the Colorado Convention Center. Established in 1993, it provides a forum for basic scientists and clinical investigators to present, discuss, and critique research on the epidemiology and biology of human retroviruses and associated diseases, including HIV, hepatitis viruses, SARS-CoV-2, mpox, and related conditions.
The conference facilitates the exchange of ideas, accelerates progress in research, and highlights discoveries through evaluated abstracts and presentations.
