STI & HIV World Congress 2025

The International Society for Sexually Transmitted Diseases Research (ISSTDR) exists to promote research on sexually transmitted diseases and facilitate the timely exchange of information among research investigators. To these ends, ISSTDR sponsors a biennial, interdisciplinary scientific meeting, at venues that historically have alternated between Europe and North America.

During the three decades since the Society was founded, the ISSTDR meetings have been the premier scientific conferences that address the entire breadth of research on STD, including HIV infections and the acquired immunodeficiency syndrome, and encompassing microbiology, virology, immunobiology, pathogenesis, and other basic sciences; clinical sciences, social and behavioral sciences, epidemiology, and prevention; and research in health services, public health, and prevention policy.
