The world-wide vaccination campaign has led to a 99% reduction in polio cases since 1988.1
Risk areas for Polio
The polio virus lives in the intestine and spreads from person to person through coming into contact with the faeces of someone who has the infection.1 Eating food or drinking water contaminated by the faeces of someone who has polio can also transmit the disease.3
Most countries are now free of polio (see map). The risk of polio is greatest in Afghanistan and Pakistan.1 Certain other countries are also affected.2
Most people will not experience any symptoms.3 Those who do may get a flu-like illness up to 3 weeks after infection, including symptoms such as fever, fatigue, headache, vomiting, stiffness of the neck and pain in the limbs.1,3
Polio can be fatal and cannot be treated.1 Severe polio causes paralysis in 1 in 200 people, mainly of the legs and sometimes of the muscles used to breathe.1
