Is soul vortex saving me from disease?

[Graeme Dice]

Disease prevents a unit from healing to full hitpoints at the end of every turn, causes one hitpoint of damage at the end of every turn, and tends to cause other afflictions either through the damage or through some other mechanism. Units that regenerate will not die from disease as they will still heal at the end of every turn, though they will still gain afflictions. Undead and demons are completely unaffected by disease. Any unit that is healed during battle, either through regeneration, the healing spells, or life drain effects (soul vortex, wraith sword, hell sword, blood thorn, etc.) will not die from disease as its hitpoints can be replenished during battle.
