Smallpox Skin Lesions: Clinical Presentation and Historical Documentation #3674924 (License: Personal Use)

The image displays two hands and forearms densely covered with firm, rounded, umbilicated pustules-a hallmark of variola major infection. The lesions are uniformly distributed, raised, and appear tense and opaque, consistent with the late eruptive stage of smallpox (days 7-14 post-rash onset). The surrounding skin shows minimal erythema, emphasizing the discrete yet coalescing nature of the vesiculopustular eruption.

This image is commonly used in medical textbooks, WHO archives, and epidemiology resources to illustrate smallpox pathology; it serves educational, historical, and biosafety training purposes, especially for recognizing orthopoxvirus infections in differential diagnosis.
