|Description:||Viewed from above, this image depicts a chickenpox scab (left), and smallpox scab (right) as a demonstration in comparative morphology. See PHIL 14761, for another smallpox-chickenpox scab comparison.|
Unlike smallpox, chickenpox lesions are superficial, and on any one part of the body, lesions can be 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.
