smallpox rash

Smallpox rash typically begins as flat red spots that quickly become raised bumps. Over a few days, these bumps develop into pus-filled blisters that are about the size of a pea. The rash often starts on the face and then spreads to other parts of the body, including the arms, legs, and trunk. As the infection progresses, the blisters become pustules and then scabs, eventually falling off. The rash is usually deep and well-defined, with lesions often at the same stage of development across the body. This characteristic pattern helps distinguish smallpox from other rashes.
