As I understand it, “hidden” is a relative thing. Before exposure one’s immune system doesn’t know what to look for, after exposure, and immune response, one’s T and B cells have a much better chance. That’s why denovo immune response to an epitope may not be sufficient, but once the immune system has been ‘exposed’ or ‘educated’ the response is much more specific. There are two parts to the immune system, innate, basically structural, and adaptive (T’s and B’s) that can be primed with certain factors to create a very precise response. The long term nature of immune response is dependent on those cells, which come in number of different ‘flavors’. Tissue Resident Macrophages hang out in the area of initial infection, waiting for “that guy” to show up again. They can sit relatively dormant for years. I don’t want to mislead, our understanding of the long term memory function of the immune system isn’t completely understood. And so we don’t know how long a given immune response will last, at least not yet. Does that help? I’m not an immunology prof, or researcher, so I may not have been clear.

This is specifically the bit I’m struggling with. How will they know it’s “that guy”?
It’s a bit like saying “We know this criminal uses disguises. We’ve given everyone copies of his mugshot, which they’ve used for target practice. Now if he wanders in wearing a disguise, people will recognise him.”

I guess this is the answer?
Going back to my analogy, you’re saying his disguises are pretty simple. So he might wear glasses or a fake beard, but he isn’t likely to turn up in a full clown outfit, with multi-coloured hair, make up, and a big red nose.
