Polio is a highly infectious viral disease that largely affects children aged below five years, according to the World Health Organization (WHO). There is no cure for polio; however, it can only be prevented by immunisation. The polio vaccine, given multiple times, can protect a child for life. Initial symptoms of polio are fever, fatigue, headache, vomiting, stiffness of the neck and pain in the limbs. One in 200 infections leads to irreversible paralysis (usually in the legs). Among those paralysed, 5–10 per cent die when their breathing muscles become immobilised.
