Progress towards polio eradication
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 WHO region have recorded zero cases for three consecutive years while meeting surveillance targets, the region can be certified as polio-free.
