I guess we still don't know why HIV needs our immune cells to reproduce and not others less important. It's absurd since the virus is destroying his own host. Like ourselfs with the planet. Why not try to reprogam the virus telling him to infect something else? What is the engine that keeps HIV infecting immune cells? Is there an explanation?
It's a great question. There are other examples of viral infections like ebola virus which rapidly kill the host, whereas herpes viruses can stay dormant in host cells for a life time. The explanation is elusive.
