Accepted Answer

Smallpox has been eliminated as a naturally occurring infection in human beings, and this was achieved through widespread vaccination programs across the world. It is believed that smallpox only had a human reservoir, and thus, its elimination was highly feasible through vaccination efforts. Although rare, smallpox can still be found in laboratories or through bioterrorism activities.
