One of the most pressing problems is the infection of a poliovirus called poliovirus, which causes the virus to become paralyzed or die. The latter, as a result of the provision of periodic vaccines, but its threat continues to threaten many developing countries,
The infection occurs from one person to another through several means, such as contaminated food, drink, mucus, faeces and phlegm from the transmitting mouth. Once the virus enters the mouth or nose, it spreads rapidly through the throat and intestines and then travels through the blood to infect different parts of the body This period is called incubation of the virus, which takes from one to two weeks.
The virus branch after entering the body into three tracks are:
1 – development of the disease: in which the patient does not appear symptoms of the phenomenon, and the initial symptoms, including: fever, vomiting, feeling tired and pain accompanying the throat, and continue these symptoms for two days or less.
2 – Non-paralytic: This case is accompanied by symptoms appear more deadly than the previous, the same clinical symptoms, but more severe, in addition to pain in the neck, hands, feet and back, and may be accompanied by meningitis or muscle spasm.
3 – paralytic: This type affects the spinal cord or the brain or rheumatism affects both, and symptoms associated with this type loss of reflex and muscle spasm, and softness in the peripheral organs.
One of the problems associated with poliomyelitis is post-polio syndrome, which is defined as a range of symptoms or signs that are likely to occur long after the disease, specifically 25-35 years after the previous symptoms but accompanied by other symptoms, such as: Muscles are generally in disarray or atrophy, weak joints and fatigue when exerting any effort, difficulty breathing and swallowing, and problems associated with sleep like choking.
A common complication of polio is urinary tract infections, pneumonia, bowel problems, myocardial infarction and shortness, permanent or temporary disability. In some cases, the patient may die from lung dysfunction or syndrome. Post poliomyelitis, which appears at a later stage as mentioned above.
The risk of children begins to decline if the child is eaten at early stages of childhood, and if there is confusion with the carriers.
Such vaccines are given to activate the child’s immune system, which has the ability to form antibodies that are able to resist and eliminate the pathogen before the outbreak of such viruses that kills the child.
