Re-reading Revelations from the Mouth of a Madman, it occurs to me that by the latest rules clarifications in Numeria: Land of Fallen Stars, page 24, the Dragon Worm parasite should be classified as an "infestation" rather than a "disease." This makes it a bit more dangerous, as on top of the natural immunity to remove disease you've given it (which would normally still handle infestations), it ignores immunity to disease.
