This is called treatment as prevention.

HIV treatment involves taking medicines that slow the progression of the virus in your body. HIV is a type of virus called a retrovirus, and the combination of drugs used to treat it is called antiretroviral therapy (ART). ART is recommended for all people living with HIV, regardless of how long they’ve had the virus or how healthy they are. ART must be taken every day, exactly as your health care provider prescribes.
What Is HIV Drug Resistance?
Drug resistance can be a cause of treatment failure for people living with HIV. As HIV multiplies in the body, it sometimes mutates (changes form) and produces variations of itself. Variations of HIV that develop while a person is taking ART can lead to drug-resistant strains of HIV.

In 1996, UNAIDS (the Joint United Nations Programme on HIV/AIDS) was established to lead a multisectoral response. In 2000, the United Nations General Assembly adopted the Millennium Development Goals, which committed to ‘halting and reversing the AIDS epidemic by 2015’. In 2002, The Global Fund to Fight AIDS, Tuberculosis and Malaria was established as a financing mechanism to attract and invest resources to end these three diseases. A year later, in 2003, the United States President’s Emergency Plan for AIDS Relief (PEPFAR) was launched, the largest ever bilateral international health initiative.
