INTRODUCTION
Over there look like a girl trying hard to drag her body on the floor and cause abrasion on her knee while an elderly sell old items from his wheelchair to raise some money for food and there is also a young man moves hardly, aided by obsolete surfboard. Just imagine about the agony and paralysis of the muscles that become flabby and shaky and may not heal back. This situation describes how polio suffered and seized their ability to walk forever in their life. Polio (or poliomyelitis) is a disease that can cause lameness among children. It is caused by an infection with the poliovirus. Poliovirus is a very contagious virus that can spread easily from person to person. Poliovirus is a single-stranded RNA virus from the family Picornaviridae and genus enterovirus, and it remains stable in and survives under acidic conditions. Poliovirus only infects humans, and it is more common during summer in temperate climates. In tropical climates, there is no seasonal pattern (Parker SP (ed.), 1998). This disease can be diagnosed by clinical symptoms, detection the presence of virus in feces and antibody detection in blood sample (Shafinaz S.M, 2000). It is usually spread through contact with stool of the infected person known as fecal-oral transmission, for an example, by changing an infected baby’s diapers, and through contact with infected respiratory secretions or saliva known as oral-oral transmission such as through airborne droplets, in food or in water (Neil Z.Miller, 2004). The virus then enters the body by nose or mouth, then travel and incubates in intestine. Following polio transmission, a person does not become immediately sick. A person who is infected with polio can spread polio about 7-10 days before symptoms occur. Symptoms usually start to occur from about one to the three weeks after...
