Undetectable HIV poses ‘zero risk’ of sexualtransmission - W.H.O says

Updated: Jul 26, 2023

olicy documents don’t usually trigger excitement. But at this week’s 12th International AIDS Society Conference on HIV Science, a rare thing happened when the World Health Organization presented its latest brief.

“People living with HIV who have an undetectable viral load, have zero risk of transmitting HIV to their sexual partners,” Lara Vojnov, technical officer at WHO’s Department of global HIV, hepatitis and sexually transmitted infections programs, said before a packed room of delegates who erupted in applause.

For many people working on HIV this information is not new. A campaign that started in 2016, called “U=U,” which is short for “undetectable equals to untransmittable,” was essentially making the same argument and WHO has also included this information in its HIV treatment guidelines.
