Viewed from above, this 1977 image depicts a smallpox scab (left), and chickenpox scab (right), as a demonstration in comparative morphology. See PHIL 3326, for another smallpox-chickenpox scab comparison. Unlike smallpox, chickenpox lesions are superficial, and on any one part of the body, lesions are found to be in different stages, i.e. papules, vesicles, and crusts. Also, chickenpox rarely has lesions on the palms and soles, which is not the case with smallpox.
