Countries with wild poliovirus transmission are considered endemic. Countries are shown as polio-free (not certified) if they have demonstrated the absence of wild poliovirus transmission. When all countries in a World Health Organization region have recorded 0 cases for 3 consecutive years while meeting surveillance targets, the region can be certified as polio-free.
Note: The country Nauru already eradicated polio in 1910, which explains the starting date of this map. The first "larger" countries' eradication of polio can be seen after 1960.
