People with HIV who are undergoing effective treatment cannot pass on the virus through sex, scientists have said, claiming the end of the pandemic could be in sight.
Researchers tested 1,000 gay male couples – one HIV positive and taking antiretroviral drugs to suppress the virus and the other HIV negative – and found no cases of transmission over eight years.
Experts said the results were a “powerful message” that should be shared widely.
Dr Michael Brady, medical director at HIV charity Terrence Higgins Trust, said it was “impossible to overstate the importance of these findings”.
“The study has given us the confidence to say, without doubt, that people living with HIV who are on effective treatment cannot pass the virus on to their sexual partners.
“This has incredible impact on the lives of people living with HIV and is a powerful message to address HIV-related stigma.”
