Most viruses have no cure… What does this imply?
In: 0
It doesn’t *imply* anything. It means that human immune system is good at keeping check on many viral infections, especially after the initial ones. Some viruses are especially good at hiding in inaccessible tissues like nerves, and they are very hard for immune system to get rid of because it can’t get there. Some infections become dormant – the immune system recognizes infected cells who are misbehaving, but not the viral material inside the cell if it doesn’t do anything for a while. And some of viral DNA is permanently incorporated in our DNA (around 8%, and many more sequences seem to have viral origin too).
