* Historical Smallpox Eradication Data (1950-1980)
|
|
*
|
|
* This dataset represents one of humanity's greatest public health achievements:
|
|
* the complete eradication of smallpox through coordinated global vaccination.
|
|
*
|
|
* Data Sources:
|
|
* - World Health Organization Archives
|
|
* - CDC Historical Records
|
|
* - Fenner et al., "Smallpox and its Eradication" (1988)
|
|
*
|
|
* Data Structure:
|
|
* - Endemic countries with decade-by-decade status
|
|
* - Vaccination campaign intensity by country
|
|
* - Last known cases with exact locations
|
|
* - Historical milestones and significance
