The American Conference for the Treatment of HIV: ACTHIV® is the premier conference in the US dedicated exclusively to the frontline care team and its members who are caring for persons living with or at risk of acquiring HIV. The conference delivers information on new developments and research findings that can be rapidly translated and directly applied to the clinical setting. ACTHIV® Institute board members, Program Planning Committee, Conference chairs and speakers are all volunteers. Registration fees, donations, and other funding received for the Conference support the educational work of ACTHIV® Institute. Thank you for your continued interest and support of the ACTHIV® 2024 Conference. The planning committee of the American Conference for the Treatment of HIV® (ACTHIV®) believes an in-person conference provides the best learning experience as in-person attendees are able to learn from one another as well as from expert clinical faculty educators. At ACTHIV® 2024, those who attend in Atlanta will be able to interact and ask questions not only of our faculty educators, but also of each other, our session co-chairs, and our exhibitors. You can also take advantage of learning opportunities beyond the conference sessions including the poster session, exhibit hall, satellite symposia, and the New Providers Track, which is designed specifically for care team members who are newer to caring for people with HIV*. And of course there will be plenty of networking opportunities during breakfasts, breaks and lunches daily as well as during the Welcome Reception on Thursday evening and the Networking Hour on Friday evening for attendees to build their professional networks and interact with HIV team members from across the US. We recognize that the demands placed on care team members in the current healthcare environment might make traveling to an in-person conference difficult so we are pleased to again offer a virtual attendance option. As an added bonus, whether you attend in person or virtually, you will be able to access all the conference educational sessions online for three weeks after the learning event— providing you with an opportunity to re-engage with the sessions that are most relevant to your practice.
