when I first heard about U=U, I had, I think, some of the same reservations that I think other people are experiencing now, which is that if you don't include the sexual transmission part of it, it sounds too good to be true. And in fact, at this point, with our understanding of the research, it is too good to be true. So U=U is applying to the sexual transmission of HIV, not potential transmission through, vertical transmission through pregnancy, or potential transmission through sharing injection drug materials. So initially, I had some concern, because I thought it was maybe too simplistic, but then when it actually needs to be always accompanied by the sexual transmission, and then it is science - it is sound science. When I realized that, that it was specifically around sexual transmission, then for me, it was very exciting. And I understand that organizations have, in many respects, I'm assuming just not had the time or taken the time to to really grasp this. But I think that this is something - is really the same as 20 years ago, when combination therapy came out, or the cocktail as we called it then. It's so important that people have to get their heads around it, they have to take the, you know, close the office for a day or have a weekend retreat, or they have they have to get their heads around this because this is absolutely vital to their clients. And we need to be shouting it from the rooftops. We need to really help other service providers, clinicians, as well as people living with HIV and their sexual partners, know this information and be comfortable with this information because it truly is ground-breaking.
