Multinational Undetectable = Untransmittable (U=U) Call-to-Action

Top Health Officials Call on World Leaders to Fully Integrate Undetectable = Untransmittable (U=U) into the Global HIV Response at AIDS 2022

National U=U supporters, Canada and the United States, affirm importance of U=U and call for global support of its critical message


For decades, the International AIDS Society (IAS) has convened leading global HIV scientists, clinicians, other service providers, and advocates to generate consensus on how to overcome the HIV epidemic. The theme of AIDS 2022 in Montreal, Canada is “re-engage and follow the science.”

Throughout the history of the epidemic, following the science has transformed heartbreak into hope, sickness into health, and death into life. In 2016, a group of advocates living with HIV followed the science and sparked a global movement celebrating the fact that effective HIV treatment prevents sexual transmission of the virus.

The evidence demonstrated zero sexual HIV transmissions when a person living with HIV on antiretroviral therapy achieved and maintained viral suppression (<200 copies/mL)12345. In response, advocates formed the Prevention Access Campaign (PAC) in 2016 to build scientific consensus6 around and disseminate the revolutionary but largely unknown research finding through the Undetectable = Untransmittable (U=U) campaign.

Since then, this knowledge has transformed what it means to live and love with HIV across the globe. To-date, over 1,000 official U=U partners from all sectors in 105 countries7 have signed on to the campaign to share the message.

As global leaders once again meet to discuss the way forward in ending the HIV epidemic, national early adopters of U=U are calling on other nations around the world to support the evidence-based U=U message, and to ensure that U=U is fully integrated into national HIV responses in order to accelerate progress towards ending the global epidemic.
