Founded in 1923, the International Union against Sexually Transmitted Infections (IUSTI) is the oldest international organization in the field. Its core objective is the achievement of international cooperation in the control of STIs, including HIV. Because IUSTI is international in scope, the various IUSTI regions hold regular regional meetings and IUSTI hosts World Meetings annually. The IUSTI focuses on the research, medical, social, and epidemiological aspects of STIs and HIV/AIDS. IUSTI is on the Roster of the United Nations Economic and Social Council and is an Official Non-Government Organization in Consultative Status with the World Health Organization (WHO). IUSTI is a voluntary body of unlimited duration, without any political, religious or social ties.
Established in 1977, the ISSTDR promotes research on sexually transmitted diseases and facilitates the timely exchange of information among research investigators – addressing the entire range of the biomedical, behavioral, and social sciences related to STIs and HIV. ISSTDR organizes biennial, interdisciplinary scientific meetings.
The joint ISSTDR-IUSTI Congress is renowned as a global platform for sharing knowledge, fostering collaboration, and addressing challenges related to the prevention, diagnosis, treatment, and advocacy of sexually transmitted diseases and infections. This Montreal 2025 Congress will bring together a diverse range of researchers, clinicians, healthcare, social and public health workers, and advocates from around the world to exchange ground-breaking insights, innovative approaches, and evidence-based best practices. These two respected organizations are dedicated to advancing research, improving patient care, and promoting sexual health worldwide.
We are pleased to inform you that the STI & HIV 2025 World Congress will be accredited. The professional accreditation details will be published in due time for the Congress, along with the launch of the full program.

The creative concept designed to represent the STI & HIV 2025 World Congress was developed around the event’s thematic “Sexual Health for All”, expressed through diverse sexualities and forms of sexual expression. Inspired by diversity flags, the idea was to distillate graphically the essence of inclusivity, representing in an abstract way the infinite mosaic of people, in all its shapes and colours. To achieve this, we approached graphics as deconstructed iconic flags to create a set of minimalist themed tiles made out of the original style of lines and colour palette.
Using square tiles as a modular unit, we created colourful combinations to represent this diverse mosaic of people: everyone interested, involved and/or touched in some way by the topics of this prestigious World Congress. The graphic device can be connected and recombined in endless variations and formats as blocks, lines or icons. The goal was to create a brand image that could also be deployed as a series of visuals translating into a unique, memorable, approachable image communicating the innovative, global and unifying spirit of this special event.
