Plans for the 28th Conference on Retroviruses and Opportunistic Infections (CROI 2021) are in development as the COVID-19 pandemic continues to evolve. At this time, it is unclear if travel to Chicago in March will be safe or practical due to the COVID-19 pandemic, and we are planning for a virtual component for all attendees and speakers. CROI 2021 will include a virtual component that features 4.5 hours of live (real-time) interactive and engaging sessions in a variety of formats. The deadline for the submission of General Abstracts has been extended to December 1, 2020 (subject to further extension). Other milestones are listed below are subject to change.
