The latest evidence shows that patients who have HIV and are regularly taking their treatment are not going to spread the disease to other people during sex. It seems that the sexual transmission of HIV virus is non-existent when a person who is already infected is on treatment, regardless if they are in a homosexual or heterosexual relationship. This data is from a large scale study of men in homosexual relationships, which was presented at the International AIDS Conference on HIV Science in Paris this month.
Scientists who specialize in HIV have also highlighted the “Undetectable equals Untransmissible” which is a campaign that hopes to encourage staying on treatment for HIV not just for themselves, but to make sure that the disease won’t be spread to anyone else they might be in a sexual relationship with. Although scientists have said that a new vaccine against HIV does show potential, it is still, however, far from being the solution to the disease.
During the study, which is the largest trial on risks associated with HIV among men in homosexual relationships, the scientists collected data on sex lives and HIV rates of well over 350 of couples where one person is infected with HIV. The participants of the study were from Australia, Thailand, and Brazil.
During the study, each couple had to report their sexual activities on their arrival at the clinic that conducted the study, and the couples were also tested to see is any new infections have been happening.
Andrew Grulich, professor of epidemiology at the University of New South Wales in Australia, the head of the conducted study was very excited about the results and has commented: “There was not a single linked HIV infection in these couples. Nobody became infected from their partner.”
There were only three new infections found in total during the course of the trial, however, those cases were not the result of transmission of the infection from the partner involved in the study but rather from a sexual relationship with someone outside of the relationship.
