"In recent years, an overwhelming body of clinical evidence has firmly established the HIV Undetectable = Untransmittable (U=U) concept as scientifically sound, say officials from the National Institutes of Health. U=U means that people living with HIV who achieve and maintain an undetectable viral load—the amount of HIV in the blood—by taking and adhering to antiretroviral therapy (ART) as prescribed cannot sexually transmit the virus to others. Writing in JAMA, officials from NIH’s National Institute of Allergy and Infectious Diseases (NIAID) review the scientific evidence underlying U=U and discuss the implications of widespread acceptance of the message."
"In the new commentary, NIAID Director Anthony S. Fauci, M.D., and colleagues summarize results from large clinical trials and cohort studies validating U=U. The landmark NIH-funded HPTN 052 clinical trial showed that no linked HIV transmissions occurred among HIV serodifferent heterosexual couples when the partner living with HIV had a durably suppressed viral load. Subsequently, the PARTNER and Opposites Attract studies confirmed these findings and extended them to male-male couples. "
