Is a Person Contagious During the Smallpox Incubation Period?
A person is not contagious during the smallpox incubation period. He or she will typically become mildly contagious at the point when symptoms begin. A person is most contagious at the onset of the smallpox rash. At this stage, the infected person is usually very sick and not able to move around in the community. Risks of smallpox transmission may last until all scabs have fallen off.
