Major Takeaway
Clinical manifestations of smallpox typically appear after an incubation period of 10 to 14 days and include high fever, severe headache, back pain, malaise and sometimes abdominal pain, vomiting, and diarrhea. In two to four days, enanthem occurs, which is a rash on the mucous membranes of the tongue and palate. This is followed by the onset of an exanthem, or a red, macular rash that typically starts at the face, distal extremities, hands, and soles of the feet and then spreads to the trunk and proximal extremities. Over the course of four to five days, the lesions evolve from macules to papules to vesicles, filled with clear fluid, which can then turn into pus, giving rise to pustules. As these pustules pop open, the pus dries out, and crusts form. An important characteristic of the smallpox rash is that all lesions are at the same stages of development at a time.
