The Hoffan Disease isn't a disease, it's a poison which renders humans immune to Wraith feeding.

With a 30% casualty rate, down from the est. 90% originally.

Spoilers for S.5:

Spoiler:

The Wraith attempt to destroy a human world for taking in humans immune to the feeding process because they're afraid that those humans will pass on the immunity. Also a radical shift in the survival rate of the poison on the human populations only furthers their fears and eagerness to find a new food source before they starve.

They forced Michael into hiding again, thus he stopped disseminating the drug. The effects are still there, which is why Beckett is going on off-world humanitarian missions.
