More and more people with HIV and/or hepatitis are going to need organ transplants, particularly liver transplants. As more of us all over the world discover we are carrying one or more of these viruses, even if we are being treated for them--or particularly if we are being treated for them--the more likely it becomes that one of our organs is going to cease working effectively. And the longer we are being treated, the longer we live and the more that chance grows.
