STI 2018
Understanding and Addressing the HIV and STI Syndemics
21-22 July 2018 at Hall 11B, RAI Amsterdam | Amsterdam, the Netherlands

HIV and other sexually transmitted infections (STIs) have been inextricably linked since the start of the HIV epidemic. A new era of global health and development driven by the Sustainable Development Goals (SDGs) offers a fresh opportunity to address the critical health issue of STIs through greater involvement, interaction and coordination between the HIV and STI fields. The 22nd International AIDS Conference (AIDS 2018) in Amsterdam, with its focus on HIV within the broader global health context, offered an excellent opportunity to explore the state of knowledge, best practices and a research agenda regarding HIV and STIs.

In the era of universal treatment and pre-exposure prophylaxis (PrEP) STI 2018 identified new challenges, emerging issues, and opportunities for research and programme implementation to counter increases in bacterial STIs (i.e. syphilis, gonorrhoea and chlamydia) being observed in many settings. The conference explored critical issues related to antimicrobial resistance and reproductive, maternal, newborn, child, and adolescent health to ensure an integrated approach.

STI 2018 combined keynote presentations and roundtable discussions to provide a thorough investigation of the current state-of-the-art in STI prevention, treatment and care specifically in the context of the HIV epidemic. It included a number of overarching themes looking at the interface between the two disease areas. The meeting was organized as an official pre-conference to AIDS 2018.
