We unite scientists, policy makers and activists to galvanize the scientific response, build global solidarity and enhance human dignity for all people living with and affected by HIV. Here are some numbers that show how we do that.


IAS change makers. Carefully selected HIV researchers, advocates, healthcare providers and others we educate to drive an evidence-based HIV response that puts people first.


IAS Members worldwide. We convene people from diverse backgrounds to drive a shared vision of a world in which HIV is no longer a threat to public health and individual well-being.
