Poxwalkers

Poxwalkers are a form of Chaos-infected undead similar to Plague Zombies who have been cursed by one of the Chaos God Nurgle's maladies, the so-called "Walking Pox," so that they can serve as unliving weapons for the Death Guard Traitor Legion. Some Inquisitors of the Ordo Sepulturum -- the new Ordo Minoris of the Inquisition dedicated to battling the undead -- claim that the Walking Pox is a variant of Nurgle's Rot, since unlike Plague Zombies, the victim's flesh often mutates even after physical death, horns and spikes similar to those of Nurgle's victims who become Plaguebearers.
