Viruses that enter and multiply in the small intestine, can enter the bloodstream and reach the central nervous system. Virus will damage motor nerves, the nerves that instruct the muscles to move. This nerve damage can not be recovered, resulting in muscles can not function again (permanent paralysis). More often experience muscle paralysis is muscle in the leg area, compared to muscles in the arm. This paralysis is also called acute flaccid paralysis (AFP). If paralysis persists, it can lead to paralysis of the two pairs of limbs (quadriplegia). In severe cases, the virus can invade the brain stem, causing breathing disorders and difficulty swallowing and speaking, which can end up with dead .
Although only one of the 200 people infected will suffer from paralysis. But some of these factors are known to increase the risk of an infected person to experience paralysis:
A person with body resistance is low for such in children
Those who had tonsillectomy (removal of tonsils glands)
Preventive what to do?
Polio can not be cured, but can be prevented through immunization. Recommendations by the Indonesian Pediatric Association (IDAI), Polio immunization is given up to 6 times. Full immunization is almost always protects a child for life, and reduce the risk of the child suffering from paralysis due to polio.
In addition, environmental sanitation such as drinking water supply and sewerage should be noted and also higine every person is needed to prevent infected by this virus.
Polio vaccine discovery is one of the biggest teroboson in the 20th century. There are two kinds of polio vaccine:
Polio vaccine containing inactivated polio virus, which is given by way of shed (oral polio vaccine, OPV). Were discovered by Dr. Albert Sabin, in 1961.
Polio vaccine contains a dead virus, inactivated (killed) polio vaccine (IPV), which was discovered by Dr. Jonas Salk, 1955, the administration by injection.
Consider the advantages and disadvantages of both types of vaccine, the polio vaccine is currently given is kind of Oral Polio Vaccine, which is given by way of dripped into the mouth.
