U=U stands for Undetectable = Untransmissable. It refers to people who are living with HIV and are in treatment for that diagnosis. The treatment is taking the levels of the virus down to such a low level in their body that the disease is therefore untransmissable to any sexual partners. A new campaign is breaking ground in Australia, pioneered by community group, The Institute of Many. Dean Arcuri sat down with Nic Holas to talk all things U=U.
