Like for example, the cold sore virus apparently stays with you for it’s whole life once you’re infected. But it has “active” phases where you actually have cold sores, and then it can go away and just lay dormant inside your body after, until it’s ready to do it again.
What’s the point of this dormant phase? How does the virus benefit from this? In my mind, it would make more sense if you always had cold sores once infected.
If we know the virus doesn’t leave and is just having a spa day when it doesn’t feel like doing it’s thing, how come we can’t get rid of it? If we know what the problem is, and where the problem is, why can’t we do anything about it?

After initial infection, the Herpes Simplex Virus (causative agent of cold sores), travel and hides on our nerves.
Viruses are usually something that can be combatted by our immune system, but our immune system does not travel around nerves.
So basically it just waits for its time that the body starts to have weaker immune system again or be in a state where the virus could replicate again, causing the on and off cold sores.
