HIV drugs stop sexual transmission of AIDS virus, say doctors

Professor Rodgers said the results "can help end the HIV pandemic by preventing HIV transmission".

The study gives a ray of hope to the gay community, reinforcing that HIV transmission could be stopped if antiretroviral therapy is used.

Although 15 men did become infected with HIV during the study, genetic testing showed that none of the viruses came from their main partner.

But, he said, maximising the benefits of the treatment, particularly for men who have sex with men, has been hard.

"Increased efforts must now focus on wider dissemination of this powerful message and ensuring that all HIV-positive people have access to testing, effective treatment, adherence support and linkage to care to help maintain an undetectable viral load".

Despite notable improvements, almost 25 percent of New York City residents with a new HIV diagnosis in 2015 had not initiated treatment within six months of their diagnosis.

She added: "Our findings provide conclusive evidence for gay men that the risk of HIV transmission with suppressive ART [antiretroviral therapy] is zero".

The study's findings also match similar findings of an earlier phase of the study looking at HIV transmission risk for serodiscordant heterosexual couples.

"Diagnosis of HIV infection is hard in the early stages of infection when transmission is very efficient, and this limitation also compromises the treatment as prevention strategy."According to the National Aids Trust, 97% of people on HIV treatment in the United Kingdom have an undetectable level of the virus, meaning they can not pass it on.

To reach the monumental goal of ending the HIV epidemic, it is important to continue to expand and target HIV testing in order to achieve earlier diagnosis and treatment for people with undiagnosed HIV infection", said McKaylee Robertson, the study's lead author and an epidemiology doctoral student at the CUNY Graduate School of Public Health and Health Policy".

Data from time periods where the partner was on pre-exposure prophylaxis (PrEP), which is a treatment taken by an HIV-negative partner to further eliminate the chance of getting HIV, was not included in the analysis.

The researchers are now thrilled to report that there were zero cases of infection amongst the couples, regardless of the amount of sexual contact. The overall government funding to specialist health services is falling.

In the study, the men with HIV had been taking antiretroviral therapy for an average of four years before it began, making the virus undetectable, defined as fewer than 200 copies per ml of blood. "The results ... provide yet one more catalyst for a universal test-and-treat strategy to provide the full benefits of antiretroviral drugs". Of the gay couples who did participate in PARTNER1, however, the rate of within-couple transmission was zero.
