Key terms: eradication vs. elimination
Eradication
The disease's natural transmission is permanently stopped everywhere in the world. Smallpox is the only human disease eradicated so far.
Elimination of transmission
No ongoing transmission in a defined area, such as a country or region. The disease still exists elsewhere and can be reintroduced.
Elimination as a public-health problem
Cases fall below WHO-set targets and services meet standards. Some cases can still occur.
Certification / validation
The formal WHO process confirming a milestone. WHO certifies polio-free status for whole regions and validates elimination as a public-health problem for individual countries.
Stories are simplified for students. Some historical researchers used methods that would not be acceptable today. Pins are placed near, not exactly on, crowded locations; hollow dots mark other places in a story, and a globe badge marks events that spread worldwide. Passport stamps aren't saved; they reset when you leave or refresh the page.
