The Conference on Retroviruses and Opportunistic Infections (CROI) was established in 1993 to provide a forum for basic scientists and clinical investigators to present, discuss, and critique their investigations into the epidemiology and biology of human retroviruses and associated diseases. The synergy of basic science and clinical investigation has been a major contributor to the success of the meeting. CROI has facilitated the presentation of important discoveries in the field, thereby accelerating progress in HIV and AIDS research. CROI highlights the latest research in HIV, hepatitis viruses, SARS-CoV-2 (including long COVID), mpox, and their related conditions.

In 2016, NMAC created the Biomedical HIV Prevention Summit (Summit) as a response to the high rates of HIV diagnosis among Black and Latinx people and the health inequities in PrEP and treatment access for communities of color.

Since inception, our goal is to translate scientific discovery and biomedical solutions for the HIV workforce into effective delivery to communities that need them the most. In its ninth year, the Summit is a unique convening of federal and state government, the HIV workforce, the healthcare sector, and PrEP users and advocates. 

The NaLa Conference previously known as the National Latinx Conference on HIV/HCV/SUD aims to provide Healthcare and Social Service Providers with innovative concepts, best practices, and new information on how to better serve Latinx communities.
