The United States Conference on AIDS (USCA) is the largest AIDS-related gathering in the U.S., bringing together over 3,000 workers from all fronts of the HIV/AIDS epidemic-from case managers and physicians, to public health workers and advocates, people living with HIV/AIDS (PLWHAs) to policymakers-to build national support networks, exchange the latest information, and learn cutting-edge tools to address the challenges of HIV/AIDS. USCA's mission is to increase the strength and diversity of the community-based response to the AIDS epidemic through education, training, new partnerships, collaboration, and networking. The Call for Abstracts has been issued by the USCA Planning Committee to solicit proposals from people working in the field of HIV/AIDS interested in convening a seminar, workshop, roundtable or poster presentation at the 2010 USCA.
