Chinese study sheds light on how well treatment may work as prevention in the real world

The study examined a cohort of people with HIV, in which research had already yielded two contradictory estimates of the effectiveness of ART in preventing transmission. Many of the original HIV-positive partners were infected through selling blood in non-sterile conditions between the early 1990s and 1998. In 1998, the practice was outlawed, but not before it had created a local HIV epidemic.

A study from the Henan province of China published recently shows that antiretroviral therapy (ART) may not be as effective at suppressing HIV and preventing onward transmission in ‘real world’ settings as it is in the best clinical practice.

The study found that ART given to the partner with HIV within monogamous heterosexual couples with different HIV status only reduced the number of HIV infections passed on between them by about 50% over the course of a study period – though its effectiveness of ART did increase over time and by the end of the study stood at 67%.
