Given the ongoing pandemic, the 28th Conference on Retroviruses and Opportunistic Infections will be held virtually from March 6 to March 10, 2021. More information will be released soon. As always, the best and most consequential original research will define the science at virtual CROI 2021, which will include research in HIV, hepatitis viruses, SARS-CoV-2, and other viral infections and their related conditions. Virtual CROI 2021 will include 4.5 hours per day of live (real-time) interactive and engaging sessions in a variety of formats. In addition, a rich program of on-demand content will be released each day. Live sessions will begin at 10:00 AM Eastern Time (US) each day: Click Here to Convert to Your Local Time.

The CROI 2021 Preliminary Agenda below is under development and will be updated as additional information becomes available.
