Figure 4.4. Physical Distribution of Smallpox Lesions Versus Varicella Lesions

Illustration shows two human figures, one on a red background and labelled 'Smallpox' and the other on a yellow background and labelled 'Chickenpox'. Both figures are covered with black dots showing where lesions are likely to appear. On the 'Smallpox' figure, most of the black dots appear on the head, arms, and legs, while on the 'Chickenpox' figure, most of the dots are on the head and torso.

Note: The smallpox lesions are concentrated on the face and extremities, including the palms and soles. In contrast, the varicella lesions are concentrated on the face and trunk.
