Anti-HIV medications suppress the viral load of people living with HIV and provide durable protection against heterosexual transmission, a study led by the University of North Carolina at Chapel Hill found. Researchers found a 93 percent reduction of HIV transmission when the HIV-infected person started antiretroviral therapy or ART at a higher CD4 cell count. The groundbreaking final results of the HIV Prevention Trials Network (HPTN) 052 study were published in the New England Journal of Medicine.
