They remain human in appearance and their strength does not change. They may mutter something, but conversation is impossible. They are not rotting; they are in a state like being afflicted by a disease. Wounds do not regenerate. [Progression of Symptoms After Becoming a Zombie] Day 1: Movements are very sluggish, and some individuals still retain their reason.

Descending from the mountains toward the town, it wanders the road while green liquid drips from its mouth. A... aaagh... uuh...
