Well, I happen to have some of the BUMED instructions on my computer for exam studying purposes...
"Active duty military members...will be medically evaluated at a designated HIV evaluation and treatment unit (hetu) to determine the status of their infection....If the active duty member has no evidence for unfitting conditions, and therefore is fit for continued Naval service, the evaluation is documented in the member's medical and dental records. If unfitting conditions are found, a medical board is convened."
IRL, I've seen very few stay in, though more now with the cocktail. In reality, a non-deployable member can make it harder on everyone else, as there are fewer Conus or shore rotations open for others.
