Polio
Polio or more correctly Poliomyelitis is a highly infectious disease caused by a virus which attacks the nervous system. This category is for questions about the disease, its history, its symptoms, its treatments, the vaccine created to combat/eradicate it and the continuing studies of not only the virus,and its treatment, but its sociological impact and the people who survived it.

disease may be defined as a failure of the adaptive mechanics of an organisms to counteract adequately the stimuli and stress to which it is subjected, resulting in a disturbance in function or structure of some parts of the body.
disease may be described as a departure from a positive state of health or well being
disease exists whenever there is an impairment of the normal state of organisms that affect the performance of vital function
disease results when, in struggle between the organisms and the individual, there is a visible evidence of the interaction
disease is the detectable reaction of the individual, the human host to a parasite (an infectious agent in a particular environment
Why is it difficult to kill polio virus inside the body?
Because viruses are not living things, so you can not "poison" them to kill them like you can bacteria and other disease causing infectious organisms that are alive. We must rely on the ability of our immune systems to render the virus particles inert/inactive by blocking their entry into our cells with antibodies, or rely on vaccines to prevent the viral infections.
In addition, it is difficult to prevent infections by viruses that easily mutate, such as the common cold. They mutate so rapidly and into so many different forms it is not possible to create a vaccine before the virus has mutated again. This is also one of the reasons why we need an annual vaccination for the flu. This is another virus that can mutate to new forms and disrupt our bodies' ability to prevent the infection with antibodies from prior infections of the same virus.
Polio is not caused by a bacterial infection. Polio is caused by a viral infection. While both are extremely tiny the viruses are 100 times smaller. Both viral and bacterial infections can sometimes be prevented by proper sanitation. Washing your hands after using the bathroom is a good way to avoid many viral and bacterial infections.
Why did Jones Salk study the polio vaccine?
Because he really wanted to make a difference and he felt bad for the people that had Polio. (I did a report on him once.)
What part of the body affected of polio?
Muscles that get information from the nervous system are affected by polio. It would be like having nerve damage at a certain level on the spinal cord. At times, a person would be so effected, they would always have to live in an iron long which would breathe for them.
Is polio virus enveloped or non enveloped?
Yes, A SSRNA one.
HIV is a retrovirus. All retroviruses are enveloped. This means when they leave the host cell after replication, they "bud" out and become coated in some of the host cell's plasma membrane which they embed with viral proteins. The capsid is then enveloped with a coating that the immune system is less likely to recognize as being foreign.
Is polio virus a microorganism?
Microorganism means very small sized organism. It can not be seen with naked eye. You have to use microscopes to see it. Polio virus is a virus. Virus are too small as compared to other microorganisms. So polio virus is included in the category of the microorganisms.
What age group is most likely to be affected by Polio?
at birth,then after 6 weeks,then in the 10th week,and 14th week.after that booster doses is given in 5 years
What impact has polio on people?
I have answered this question as the impact of the illness on the physical health of the person who has contracted it, based on information provided from the Health and wellness Resource Centre database. Other resources are available on the web at:
Centers for Disease Control and Prevention (CDC) http://www.cdc.gov/
World Health Organization (WHO) 2 http://www.who.int/ (http://www.who.int/)
There are two forms of polio illness:
Minor poliomyelitis (also called abortive poliomyelitis), which occurs primarily in young children, is the most common of the two. The illness is mild, and the brain and spinal cord are not affected. Symptoms appear three to five days after exposure to the virus and include slight fever, headache, sore throat, vomiting, lack of appetite, and a general feeling of illness and discomfort.
Major poliomyelitis (also called paralytic and non paralytic polio) is a more severe illness that develops approximately 7 to 14 days after exposure to the virus. Symptoms include fever, severe headache, stiff neck and back, and deep muscle pain. Some people experience temporary abnormalities of skin sensation. Muscle spasms and a tendency to retain urine are common. Muscle weakness and paralysis may develop rapidly or gradually during the time fevers are occurring, but paralysis does not continue to get worse afterwards. The disease most commonly affects the muscles of the legs, but the areas affected depend on what portion of the spinal cord is damaged and can include the arms, abdominal muscles, chest, neck and throat muscles. Respiratory failure occurs if the virus infects the nerves in the spinal cord that control the respiratory muscles of the chest or the parts of the brain involved in respiration.
Recovery from minor polio occurs in about three days. The fever and other symptoms of major polio can go away within days, but paralysis can be permanent. Some muscle function may return during the first six months after the acute illness, and improvement can continue for two years.
People with minor illness and nonparalytic forms of polio recover completely, and most people with major illness who were paralyzed also recover completely. Less than 25% of people with polioare disabled for life.
Even though you can recover completely from polio symptoms, poliodoes leave behind some damage. As you age, your nervous system may become less able to compensate for the damage that polio has caused, so symptoms may gradually reappear. If this occurs, it can happen 15 or 30 years after the polio infection was active. Recurring symptoms from polio are called post-poliosyndrome.

Where is Polio most commonly found?
Polio is transmitted through saliva. This could be found in lakes, pools, sharing a drink, etc.
When did Jonas Salk discover the polio vaccine?
After years of research, his discovery was confirmed in early 1955 and announced to the press and public in April 1955.
What does polio infect in your bodies?
Polio infects the central nervous system in your body. At this part of the central nervous system, nerves go to the muscles. A person is paralyzed from this level of the cord down.
Can a healthy man marry a polio affected woman?
yes, an healthyman can mary a polio affected women and can be with her till his death
The maximum state of paralysis is usually reached within just a few days. The remaining nerves begin to grow branches to compensate the destroyed nerves. This process continues for about six months.
How was the polio vaccine invented?
The first ever polio vaccine was developed by Dr Jonas Salk at the University of Pittsburgh in the early 1950s. It was a killed vaccine that was tested in clinical trials in 1954 and ultimately gained government approval by 1955 for use on the common public. There is also another polio vaccine that was developed by Dr Albert Sabin. This vaccine was a live version of the polio virus and is taken orally. It was approved for use in the general public in 1963. == == == == == == == ==
Why was a vaccine against polio needed in a America?
because that vaccine contains alive polio virus which caused polio in healthy people therefore america banned it and sell it in asia fpr frewe among muslims
What did the polio vaccination contain?
The first vaccine was developed in 1952 by Jonas Salk.
The vaccine was made from dead viruses grown in a monkey kidney tissue culture. Heat and formaldehyde were used to kill the virus.
