As the directing and coordinating authority on international health, the World Health Organization (WHO) takes the lead within the UN system in the global health sector response to HIV/AIDS. The HIV/AIDS Department provides evidence-based, technical support to WHO Member States to help them scale up treatment, care and prevention services as well as drugs and diagnostics supply to ensure a comprehensive and sustainable response to HIV/AIDS.
The International AIDS Conference (IAC) is held every two years and brings together some 25,000 scientists, government representatives, health workers, activists, corporate leaders, and people living with HIV and AIDS. It is an opportunity to share new scientific research and engage in dialogue concerning the global response to HIV/AIDS. The theme of this year's conference was "Universal Action Now," emphasizing the need for continued commitment on the part of all stakeholders contributing to the global response to HIV/AIDS - including WHO.
