For many countries, polio outbreaks are a distant memory, with 80% of the world’s population now living in certified polio-free regions. However, in certain countries around the world, polio remains a very real threat, particularly to children under the age of 5. According to the WHO, the failure to eradicate polio from these last remaining polio strongholds could result in as many as 200,000 new cases every year, within 10 years, all over the world.1
