CROI 2022: summary of basic science research in HIV and SARS-CoV-2.

The Conference on Retroviruses and Opportunistic Infections (CROI) 2022, which was held as a virtual conference, continues to serve as the preeminent forum that features research advances in HIV-1 and its associated coinfections. The conference has extended its area of coverage to include research advances in SARS- CoV-2. As pointed out in the presentation from Hatziioannou in the New Investigators workshop, there has been an explosion in research activity on SARS-CoV-2 that has eclipsed that for HIV-1. In the past 12 months, there were approximately 6600 publications on HIV-1 and approximately 64,000 on SARS-CoV-2. Although these numbers include review articles, they reveal the tremendous response by researchers to the existential threats posed by lentiviruses and coronaviruses. This poses challenges for any conference committee tasked with selecting abstracts for presentation from the large number submitted for consideration. CROI organizers have consistently been able to assemble a program that, through invited presentations, abstract-driven talks, posters, interactive sessions, workshops, and symposia, showcases the most recent research advances.
