Cape Town - New tools developed by researchers at the University of the Western Cape (UWC) can pinpoint resistance to antiretroviral (ARV) therapies for HIV.
The HIV inside people taking ARVs changes all the time. Sometimes, especially if a person is not taking the right ARVs or isn’t adhering to their treatment, strains of HIV will develop against which the drug do not work. These strains reproduce and become the dominant HIV in the person’s body. The ARVs no longer work, and the person has drug-resistant HIV.
