Role of viral suppression in HIV treatment and prevention and its potential in addressing harmful laws and discrimination.

The World Health Organization's (WHO) global public health mandate includes a focus on expanding access to HIV testing, antiretroviral therapy (ART) and treatment monitoring to improve the clinical management of HIV, achieve sustained viral suppression, and prevent HIV-related incidence, morbidity, and mortality. This article documents key moments in research and WHO policies that have informed how ART is applied within HIV programs, including as a prevention tool with the potential to support efforts to address HIV-related discrimination. For more than 20years, WHO has promoted the benefits of HIV treatment including as part of the approach to prevent the mother-to-child transmission (vertical transmission) of HIV. WHO guidance has followed, and continues to follow, the evolving evidence. In 2023, WHO continues to clarify that there is zero risk of sexual HIV transmission when a person living with HIV has an undetectable viral load and an almost zero or negligible risk of sexual transmission when a person living with HIV has a viral load of ≤1000copies/mL - helping to evolve the focus of community campaigns and health worker training to include a focus on 'virally suppressed' while also continuing to emphasise the ultimate goal of achieving an undetectable viral load. This evolution does two things: first, it strongly reasserts the evidence around there being no chance of transmission if a person has an undetectable viral load; and second, it provides an extremely strong degree of confidence that, similarly, individuals who are virally suppressed will not pass on the virus sexually. WHO is now encouraging positive and clear messaging to highlight that the consistent use of ART prevents onwards HIV transmission.

Partnership, sex, and marginalization: Moving the Global Fund sexual orientation and gender identities agenda.

After almost three decades of work to address HIV and AIDS, resources are still failing to adequately address the needs of the most affected and marginalized groups in many societies. In recognition of this ongoing failure, the Global Fund to Fight AIDS, Tuberculosis and Malaria (the Global Fund) has approved a sexual orientation and gender identities (SOGI) Strategy. The Strategy is designed to help its investments more effectively reach men who have sex with men; transgender populations; male, female, and transgender sex workers; and women who have sex with women. The Global Fund financing model is unique and based on ideas of broad partnership. It emphasizes the importance of country-ownership while ensuring that work is appropriately targeted, evidence-based, and rooted in principles of human rights. The classic international development tension of pursuing a rights-based agenda, while also supporting strong country ownership, has moved the Global Fund into a more substantive technical, advocacy, and policy arena, resulting in the creation of the SOGI Strategy, which emphasizes the needs of marginalized groups. A strong commitment to participation and consultation was crucial during the development stages of the Strategy. Now, as the Strategy goes live, it is clear that progress will only be achieved through continued and strengthened partnership. The diverse partners - in particular the governments and other stakeholders in recipient countries that helped develop the Strategy - must now commit to stronger collaboration on this agenda and must demonstrate bold leadership in overcoming the considerable technical and political challenges of implementation that lie ahead.
