In early 2016, the Undetectable=Untransmissable (U=U) campaign began in an effort to ensure the message of U=U was shared with community; at the time there was much resistance to the science and hesitance to share the message with providers and people living with HIV. Led by people living with HIV, the campaign took off and now has become global; the U=U slogan is now universally known in the HIV arena around the world. This session provides an overview of the global campaign today, some of the main community impacts, and remaining community challenges. Key issues covered include: the impact of U=U on dismantling HIV related stigma; importance of ‘language matters’ when communicating the U=U science; and the impact of U=U on the sexual and reproductive lives of PLHIV. Community concerns discussed include the continued resistance to sharing the message, limited updates to existing resources to reflect the U=U science; questions about breastfeeding and syringe sharing; concerns with unequal access to testing, treatment and care; and concerns with stigmatizing and criminalizing people living with HIV who are not virally suppressed. Personal stories of PLHIV and examples of the campaign are shared to illustrate the main points.
