How is Batman infected with Joker blood?

[Wobb the Great and Terrible!!!!!]

He took the cure in Arkham City, prepared by Freeze. That's how Joker died, because Bats took the cure, saved a bit for Joker but Joker stabbed him in the back and he dropped the vial, breaking it.

So how is he still infected now? How did the cure not work? It's not because it was a temporary cure because the temporary cure was the potion that Ras gave to Bats, that wasn't prepared fully by Freeze who had been working on a cure and only needed that certain enzime or whatever that was found in Ras' blood or something, right?

I have played this through a whole bunch of times now, and unless I am missing something somewhere, it never explains how the cure only worked for a short while and now he is infected again.

And it's also not because the Scarecrow gas kind of re-activated it, because Bats was already aware he was infected because he had the chamber all ready to lock himself up once he started showing symptoms.

Anyone have any idea what's happening here? Or was it just a cheap trick used to bring back Joker?
Not complaining too much if so, because Luke Skywalker is always entertaining as the voice of Mr. J.

The cure was for the Titan infection that was killing Joker. The Joker infection was a completely unexpected side effect that didn't turn up until later. The cure didn't completely work, because Batman had a massive transfusion of Joker blood (far more than any of the other people).

I do agree they should've explained this better in-game though.

Even if it was just a cheap trick to get the Joker back, imagine Arkham Knight without him... one big shallow game.

In AC, Joker says "take my blood... I wish someone would.... this stuff is KILLING ME!!! Hahahahaha"
So it wasn't a cure for Titan infection. That was cured, which was bringing him back from the Titan creature he had turned into.
The infection Joker died from was like a mutation of the after-effects of the Titan formula.
Thus, it was literally his blood killing him pretty much.

The Batman wiki linked here by lucasj1210 doesn't even offer a proper reason why Bats is still infected, just saying that maybe it was because he only used like half of the cure, or that it was further mutated by the Titan formula or something.

Should have been explained properly I thought, either way.
As I said, I still don't mind even if it was just the only way they could find to bring back Joker, because Joker has been a highlight of this whole series, except for in arkham origins, which was a bit lacklustre compared to the rest (but still great compared to other superhero games)
