HIV-positive individuals who begin antiretroviral therapy (ART) early dramatically lower the risk of transmitting the virus to their partners.
A major study by the National Institute of Allergy and Infectious Diseases (NIAID) demonstrates that starting virus inhibitors early reduces HIV transmission risk by 96%.
Start treatment immediately
Researchers analyzed 1,763 HIV-positive individuals and their uninfected partners across four continents. Half of the HIV patients started antiretroviral therapy immediately, while the other half delayed until symptoms appeared.
Over the study period, 28 partners contracted HIV. Notably, only one transmission occurred from a participant who had begun immediate therapy.

Faster access to treatment
Many people with HIV delay medication until their health declines. This research confirms that early ART not only benefits the patient but also prevents transmission. Treatment should begin right after diagnosis.
