These symptoms, such as fever, malaise, lethargy and loss of appetite are often referred to as "sickness behavior" and are a consequence of systemically produced pro-inflammatory mediators. These inflammatory mediators signal to the brain, leading to activation of microglial cells, which in turn, signal to neurons to induce adaptive metabolic and behavioral changes.
