Once a dreaded killer of children that caused the deaths of millions of Native Americans after the arrival of European settlers in the Americas, smallpox was declared eradicated in 1980 following a worldwide vaccination campaign.

Note: A surface with many blemishes is sometimes said to be “pockmarked” because it resembles the skin of a smallpox sufferer.
Note: Smallpox is the first disease of humans to be completely eradicated by a worldwide campaign of inoculation.
Note: Today, the smallpox virus exists only in laboratories.
Note: The use of smallpox is a major concern in the area of bioterrorism.
