What makes a retrovirus more dangerous than a regular virus?

The answer is there are some classes of viruses that form lifelong infections or what we call persisting infections. HIV is a retrovirus. When you get infected by a retrovirus it's always forever. It's always forever. Now scientists are not supposed to say always, so I should qualify. It's virtually always forever. Far as I know, it's so far been forever. It's true with herpes viruses, usually. It's true with some of the hepatitis viruses, usually. It's true with papilloma viruses, usually. And those viruses are mostly DNA viruses, some hepatitis viruses are not. But a retrovirus is the king of persisting infections, because quickly it inserts its genes into our DNA, into our chromosomal DNA, of the very cell that gets infected. It harbors the virus forever. You say, well, that cell will die someday. Yeah. Before it dies it usually divides, and its daughter cells will also contain the genes of HIV.
