...”Since the immune system cannot reach into those fluid-filled pockets, it cannot kill the virus there”....
So why not inject some of these areas....once you know where it’s raised it’s ugly head.
I'm not sure how feasible that would be. For one thing, the virus is not reproducing in those fluid pockets, it is just sitting there. So anti-virals meant to interrupt viral reproduction might not work. For another thing, it can't be that easy to inject the inside of the eye or some of the other fluid pockets in the body; I think some of them are somewhat inaccessible. And an eye injection...just ugh. I did read the case study of the doctor whose eyes were infected with Ebola virus... I will have to find it again to get the details, I think they treated with ophthalmic drugs.
