ABSTRACT
Sickness, or sickness behavior, is a state of altered physiology and behavior generated by the brain-immune axis during infection, which is generally assumed to contribute to host defense. Here, we examine this assumption by framing sickness as organismal-scale immunity and explore predicted parallels with immunity at the cellular and tissue scales.
