After exposure to the virus, it takes around #7-17# days for symptoms to appear.

Explanation:

The average incubation time for the smallpox virus is #12-14# days during which time the infected person feels fine and is not contagious.

Symptoms like high fever, headache, bodyache, sometimes vomiting manifest around #7-17# days after infection, progressing to a rash that develops into raised bumps and pus-filled blisters.

These blisters form crusts and scabs and, after about three weeks, the scabs fall off, leaving behind a pitted scar.
