Eradication

Eradication refers to the complete and permanent removal of a specific disease or harmful organism from all environments and populations worldwide. Achieving eradication means no new cases occur anywhere, and existing cases are eliminated. This process usually involves widespread vaccination, treatment, and public health efforts to break the disease's transmission cycle. An example is smallpox, which was declared eradicated in 1980 after extensive global efforts. Eradication is different from control or elimination, as it aims for permanent absence, preventing any future resurgence of the disease.
