During which stage might a patient begin to experience fatigue and malaise?

The prodromal stage is characterized by the onset of non-specific symptoms that often precede more severe signs of illness. During this stage, patients typically experience general feelings of discomfort, fatigue, and malaise as their body responds to infection. These symptoms are an early indication that the body is fighting off the pathogen, and they can signal the impending onset of more distinct and specific symptoms related to the illness.

In contrast, the other stages have specific characteristics: the acute stage is when the disease process is at its height and the symptoms are fully developed; the incubation stage is the period after infection and before the first symptoms appear, which means fatigue and malaise wouldn’t yet be experienced; and the declining stage occurs after the acute symptoms have peaked, often involved in the recovery process when patients might start feeling better rather than fatigued. Therefore, recognizing that fatigue and malaise are prominent in the prodromal stage aligns with the understanding of disease progression in infection control.
