Rationale: The prodromal period is the interval between the early manifestations of the disease and the time when the overt clinical syndrome is evident. Most communicable diseases are contagious during this time. Identifying the prodromal stage is crucial for early intervention and preventing the spread of the disease. While the source and causative agent are important aspects of disease control, recognizing the early signs in the prodromal stage allows the nurse to take timely actions. Constitutional symptoms occur during the active disease phase, indicating that the child has already been contagious, and early intervention opportunities may have passed.
