Initial diagnosis of smallpox is most likely based on a history and physical examination findings. Smallpox is usually localized in small blood vessels of the skin and in the mouth and throat. In the skin it resulted in a characteristic maculopapular rash and, later, raised fluid-filled blisters, characteristic scars, commonly on the face, which occur in 65–85% of survivors. The doctor may take a throat swab to make the diagnosis of smallpox. A sample from a freshly opened pustule may also be useful in diagnosis. For suspected cases of hemorrhagic smallpox, the doctor may sample fluid from a spinal tap (lumbar puncture). Viral cultures, polymerase chain reaction (PCR), and/or enzyme-linked immunoabsorbent assay (ELISA) may be undertaken to make a definitive diagnosis once the sample arrives as the lab.
