Question: 1 / 400

What characterizes varicella lesions?

Pustular lesions that crust

Puritic maculopapular lesions that become vesicular

Varicella lesions, commonly known as chickenpox, are characterized by their progression from purpura maculopapular lesions to vesicular formations. Initially, the lesions appear as small, red spots that develop into raised bumps (papules) before progressing to fluid-filled vesicles. This vesicular stage is particularly distinctive, as the lesions often crust over after a few days, which is a key feature of the infection. The intense itching associated with these lesions also sets them apart from other types of skin manifestations.

Understanding the progression of varicella lesions is essential for identifying the disease and managing symptoms in school-aged populations, particularly where vaccination coverage may impact the incidence of varicella. Knowledge of this progression helps school nurses educate students and parents about the nature of chickenpox, its contagiousness, and the importance of early recognition for appropriate management and care.
