Poliomyelitis and its symptoms:
Poliomyelitis (polio) is a highly infectious disease caused by a virus. It invades the nervous system, and can cause total paralysis in a matter of hours. The virus enters the body through the mouth and multiplies in the intestine. Initial symptoms are fever, fatigue, headache, vomiting, stiffness in the neck and pain in the limbs. One in 200 infections leads to irreversible paralysis (usually in the legs). Among those paralysed, 5%–10% die when their breathing muscles become immobilized.
Persons at risk of polio:
Polio mainly affects children under five years of age.
Prevention of polio:
There is no cure for polio, it can only be prevented. Polio vaccine, given multiple times, can protect a child for life.
