Since the early days of treatment there are questions about treatment being a cornerstone of prevention. What does it really mean to be “undetectable” – how much does this translate into being not infectious? Is there a difference between heterosexual and homosexual encounters in this context? Or more precise: Is there a difference when it comes to anal sex versus vaginal intercourse? Is the amount of virus particles in the blood and semen or vaginal fluid the same? What is the risk by not using a condom, if somebody is on treatment and the viral load is undetectable? What does it mean to have one permanent partner versus several partners? There are so many questions and one hears so many different answers and it seems the debate is ongoing. The Body.com has tried to bring together all the information about these questions and it makes an interesting reading. To read their findings please click here.
