smallpox definition

An acute and infectious disease caused by a virus and now almost completely eradicated. Smallpox was characterized by high fever and large sores on the body that leave scars.

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.
