The U=U global movement is a campaign to end HIV stigma and promote the science-based message of Undetectable = Untransmittable (U=U). U=U communicates the message that people living with HIV who have achieved and maintained an undetectable viral load through treatment can't pass the virus to their sexual partners. By joining the U=U global movement, you can help spread the message and combat the stigma that millions of people living with HIV face every day. Together, we can make a difference.
