The 29th Conference on Retroviruses and Opportunistic Infections (CROI) will be held from February 12 to 16, 2022, and will include research on SARS-CoV-2. As always, the best and most consequential original research will define the science at CROI 2022, including research in HIV, hepatitis viruses, SARS-CoV-2, and other viral infections and their related conditions. 

CROI Going Hybrid in 2022: CROI is currently planned to include both virtual and in-person participation. The in-person component, hosted in Denver, Colorado, USA, will feature additional sessions and networking opportunities. The CROI Scientific Program Committee will monitor the COVID-19 pandemic carefully in terms of changes in the safety and practicality of hosting an in-person component. Additional information will be posted as it becomes available. 

Submit a Scientific Abstract: The CROI Program Committee invites submission of original research in HIV, hepatitis viruses, SARS-CoV-2, and other viral infections and their related conditions. General abstract submission opens on September 1, 2021, with a deadline of November 1, 2021. The later general abstract submission deadline has been set to allow more investigators to submit their research for CROI 2022. General abstracts will account for the largest percentage of accepted abstracts (usually about 50% of general abstracts submitted are accepted). Data analyzed after the general abstract submission deadline may be submitted as a late-breaker if they meet a high threshold of scientific merit. The selection criteria are much more rigorous than for general abstracts, and only about 5% of late-breaking abstracts are accepted. 

Key dates and deadlines, including those for general and late-breaking abstract submissions are listed on the CROI Important Dates and Deadlines webpage. Check the CROI Website regularly for updates.
