What occurs during the prodromal stage of an infection?

During the prodromal stage of an infection, the onset of initial symptoms typically occurs, which may include generalized signs like fatigue, low-grade fever, or malaise. This stage acts as a precursor to the more acute phase of the illness where specific symptoms related to the infection start to manifest. It is characterized by the gradual introduction of the infection, without the presence of the more severe or distinct symptoms that indicate a full-blown illness. Understanding this stage is crucial, as it highlights the early warning signs of an infection, allowing for timely intervention and management before the condition escalates.
