An end to Aids disease could be in sight after Scientists landmark a study for gay men that the risk of HIV transmission with the antiretroviral treatment is zero.
The success of the medicine means that if everyone with HIV were fully treated, there would be no further infections.
Scientists studied 1,000 gay male couples – one HIV positive and taking antiretroviral drugs to suppress the virus, and the other HIV negative.
Over the course of eight years, the virus was not transmitted once.
In 2017, there were almost 40 million people worldwide living with Aids, of whom 21.7 million were on antiretroviral treatment.
Antiretroviral (ART) are medications that treat HIV. The drugs do not kill or cure the virus. However, when taken in combination they can prevent the growth of the virus.
