Mauro has been involved in the AIDS movement since the late 1990s, focussing on injecting drug use, harm reduction, access to the highest standard of care for active drug users, and the end of prohibition. Mauro was the first person openly living with HIV to address the CND plenary, and has been a member of the UN expert committee on HIV and drug use (the last denomination being Strategic Advisory Group or ‘SAG’) between 2005 and 2018.

Aditia Taslim, Advocacy Officer
Aditia has been involved in the HIV and drugs movement since 2005. His involvement started with an Indonesian-based community-led organisation, Rumah Cemara, focusing on different range of services for people who use drugs and people living with HIV in general. In the early days, his work focused on the initiation of harm reduction services for the very first time in Indonesia. He was also part of the initiation of a drug-user movement in Indonesia which eventually led to the development of a national network of people who use drugs. In 2018-2020, Aditia was one of the Asia Pacific NGO Delegates to the UNAIDS Programme Coordinating Board (PCB), bringing the voice of Asia Pacific region and his living experience as both a person who use drugs and who lives with HIV.
