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.
489 Questions
Is post-polio syndrome contagious?
No. It is a set of neurologic symptoms which exist long after polio, itself, is experienced by the sufferer.
What is the ratio of people in the us with polio?
The answer depends on whether you want the ratio of people in the US with polio compared to people with polio in the rest of the world (or the whole world), or the compared to people without polio in the US.
Are some people or age groups more susceptible than other to Polio?
The older one is, the more likely polio will exhibit serious symptoms like paralysis.
Is polio a water bourne disease?
Not specifically. But sewage contaminated water might contain virus if the disease is active in the area. It can easily be spread from person to person by contact, sneezing, coughing, etc.
How does Polio infect the body?
It usually affects your legs or arms, but in some rare cases can affect speaking, swallowing, and breathing.
Polio, also known as poliomyelitis, affects the grey matter of the spinal cord, which is the inner part of the cord.
Where are the least cases of polio in the world?
The industrialized countries of the world have fewer cases of polio because there are many more vaccinated individuals.
Is polio a hereditary disease and if not why?
Polio is NOT hereditary. It is caused by a virus, poliovirus, that is highly contagious. A vaccine exists to prevent catching the disease.
What percentage of polio cases develop postpolio syndrome?
PPS occurs in about 25% of patients, several decades after their original infection with polio. However, long-term follow-up indicates that two thirds of polio survivors may experience new weakness.
Is polio still an active disease?
Yes, as of October 2012 Polio is still endemic in three countries. These countries are Pakistan, Afghanistan and Nigeria. Polio also spreads to countries The disease has also been reintroduced to 5 non endemic countries.
The total case count for 2012 to date is 166.
The disease of polio is generally not chronic in nature. The effects of the disease, however, can have lifelong and major health consequences.
Who perfected the polio vaccine?
Two polio vaccines are used throughout the world to combat poliomyelitis (or polio). The first was developed by Jonas Salk and first tested in 1952. Announced to the world by Salk on April 12, 1955, it consists of an injected dose of inactivated (dead) poliovirus. An oral vaccine was developed by Albert Sabin using attenuated poliovirus. Human trials of Sabin's vaccine began in 1957 and it was licensed in 1962.

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.
