Contamination from poliomyelitis is spread through contact with somebody who as of now has the ailment or as an aftereffect of poor sanitation
where human waste items taint others. The mouth is the typical pathway of the infection, which then enters the blood framework. Loss of motion
generally to the arms and legs happens from sores to the focal sensory system. These sores happen when the polio infections start to attack the focal
sensory system. Clinical responses to the polio infections can extend from none to mellow manifestations looking like the normal frosty (cerebral
pain, sore throat, slight fever). These side effects can vanish in a brief timeframe, anywhere in the range of one to three days. A noteworthy sickness of

That number held firm from the mid–1950s to the early part of the following decade of the 1960s. By 1992, the quantity of reported cases all through
the world dropped to 15,406. In 1991, Peru was the last nation in the western side of the equator to report an affirmed instance of polio. Since 2001,
less than two thousand instances of polio have been accounted for worldwide every year. There were 414 reported and recorded cases worldwide in

The Global Eradication of Polio Essays
The Global Eradication of Polio
The possibility of the eradication of polio worldwide is an imminent and exciting prospect as the "goal" year quickly approaches. In 1988, the World
Health Assembly, which governs the World Health Organization, set the goal of eliminating polio from the world by the year 2010. Many
organizations have joined the effort along with the World Health Organization: the Center for Disease Control and Prevention, UNICEF, Rotary
International, Global Health Network, the US Agency for International Development, National Immunization Day, and the International Broadcasting
Bureau. Together, these "worldwidepolio partners" have implemented a strategy to completely rid the world of this disease. It is a difficult...show more

The poliovirus enters the body through the mouth, and multiplies in the throat and intestines. It may remain unmanifested for anywhere from four to
thirty–five days. Once the virus is in the intestines it has the potential to spread throughout the body by way of the bloodstream, and infiltrate into the
central nervous system. In the central nervous system, the virus can spread out along the nerve fibers and begin to destroy the nerve cells, or motor
neurons, resulting in limpness in the arms and legs. This is known as acute flaccid paralysis and this symptom of polio (also a symptom of several
other diseases) is used to uncover new cases which may have been misdiagnosed or not diagnosed at all (WHO 1999). This is a necessary procedure
in that it helps to cover all the bases in the pursuit of eradicating poliovirus from the earth.
It is important to note that paralysis does not occur in all polio cases. Acute poliomyelitis manifests itself as a two–phased disease in a small proportion
of its victims. The first phase is minor, a "non–specific febrile illness" (Prevots 1999). All patients with polio experience this phase, and only a small
percentage develops the second phase, "aseptic meningitis and/or paralytic disease" (Prevots 1999). The aseptic meningitis is inflammation, caused by
the virus, of the meninges of the

Ancient Egyptian paintings and carvings narrate otherwise healthy people with withered limbs and children walking with the help of canes at a
young age.(1) It is theorized that the Roman Emperor, Claudius was suffered from poliomyelitis because of it, he walked with a limp for the rest of
his life. Earliest recorded case of poliomyelitis was that of Sir Walter Scott. In 1773 Scott was developed "a severe teething fever which disabled him of
paralysis of his right leg".( 2)
The symptoms of poliomyelitis had been described by many ways. In the early nineteenth century the disease was known as: Dental Paralysis,
Infantile Spinal cord Paralysis, Essential Paralysis of Children, Regressive Paralysis, myelitis of the Anterior Horns cells, Tephro...show more content...
It invades the human nervous system and can cause complete paralysis in a matter of hours. Humans are only reservoir. The virus is mostly transmitted
by person–to–person spread mainly through the fecal–oral route , less frequently, by a common vehicle for example, contaminated water or food.It
multiplies in the intestine. Initial symptoms are commonly fever, fatigue, headache, vomiting, stiffness of the neck and pain in the limbs. 1 in

paralyzed. Polio mainly affects children under 5 years of age. There is no cure for polio paralysis, it can only be prevented with multiple doses of two
drops of polio
Major polio epidemics were unknown before the 20th century; localized paralytic polio epidemics began to appear in Europe and the United States
around 1900. The first report of multiple polio cases was published in 1843 and described an 1841 outbreak in Louisiana.(5)
On Saturday, June 17, 1916, an official announcement was made regarding existence of an epidemic polio infection in Brooklyn, New York. That year,
there were

Poliio Research Paper
Polio is a very contagious disease that is caused by a virus, Poliovirus, which affects the nervous system (Johnson). According to the article
Poliomyelitis, Polio transmits through fecal matter and once viral reproduction is established, poliovirus multiplies in specialized cells that are in the
intestines. They enter the blood stream to take over the central nervous system, where it spreads along nerve fibers. When they finally multiply in the
nervous system, they can destroy nerve cells which activate skeletal muscles. Nerve cells can't revive, and the affected muscles lose their job due to a
lack of nervous enervation. Muscles of the legs are affected more than the arms and extensive paralysis, involving the trunk and muscles of the thorax
and abdomen, can result in quadriplegia. Severe cases usually makes it harder for the body to breath, which in turn causes difficulty in swallowing and
talking (Poliomyelitis). Once a person receives Polio, there is no visible way of treating it as doctors can only treat the symptoms as the disease slowly
kills the body (Johnson). However, it can be prevented before a person receives it by getting the polio vaccine. Because of the vaccine, outbreaks have
been reduced significantly in the U.S....show more content...
The disease is usually caused by fungi, bacteria, or viruses (Pneumonia). Usually the germs can't get past a healthy body's guards but in a body that is
weak, the germs can get by (Pneumonia: Is It Contagious?). Pneumonia causes inflammation in the lung's air sacs, also known as alveoli (Normandin).
The alveoli fills with fluid making it harder for the person to breathe (Normandin). To treat Pneumonia, doctors usually use antibiotics as it has a high
healing rate in people, although the type is based on a number of things (Pneumonia – Treatment). Most cases are here, in the United States (Pneumonia

Informative Essay On Polio
Henrietta Lacks is a women who died 62 years ago from an aggressive form of cervical cancer at Johns Hopkins Hospital in 1951 but her cells are still
alive which are the human cell lines scientists most commonly used. George Gey is a researcher who researched cancer cell for ten more years and
found the cells from Henrietta Lacks's uterus can keep alive. He was the head of tissue culture at Johns Hopkin when Henrietta was being treated for
cervical cancer and he had been actively trying to grow an immortal cell line. They were the first human cells which grown in a lab. George Gey
named this sample Hela from the initial letters of Henrietta Lacks' name. Though Gey had the mind of a scientist and the hands of skilled craftsman, he
often got caught up in his experiments without much thought of the consequences. He relied on his wife named Margaret Grey, who was trained as a
surgical nurse, to take care of the day–to–day details of running a proper lab. More, Mary Kubicek was the lab assistant which attended an autopsy at

This vaccine was then used in a test called Francis Field Trial which led by Thomas Francis. The test began with some 4.000 children at Franklin
Sherman Elementary School In McLean, Virginia. Because the test need a large number of Hela cells, NFIP found a facility capable of
mass–producing Hela cells. In 1955, Hela cells were the first human cells successfully cloned by Theodore Puck and Philip Marcus at the University
of Colorado. At that time, Hela cells have been used for research into cancer, AIDS, the effects of radiation and toxic substances, gene mapping, and
many other scientific pursuits. Also, Hela cells have been used in testing how parvo virus infects cells of humans, Hela, dogs and

Polio, or poliomyelitis, is an infectious disease that manifests as a variety of symptoms, the most severe of which is paralysis which can lead to
permanent disability and death. Some people show no symptoms at all. Children who recover from polio at a young age may develop new symptoms
later in life ("CDC Global Health – Polio – What Is Polio?," n.d.). Polio was considered a disease of developed countries for much of the 1900s.
However, in the 1960s and 1970s, prevalence of polio in schoolchildren in developing countries across the world was found to be much higher than
in the United States (Modlin, 2010). By 2000, polio has been mostly eradicated around the world, with the number of cases having fallen by more
than 99%. Today, there are only a few countries that still have new cases of polio each year and the total number of reported polio cases is, on average,
less than 100 each year ("CDC Global Health – Polio – Updates on CDC's Polio Eradication Efforts – March 18, 2016," n.d.). Vaccinationexists for
polio, with two forms currently in use. The live poliovirus vaccination is more effective and widely used in endemic regions, while the inactive
vaccination is used in areas where polio has been eradicated (Modlin, 2010).

Essay on Polio Vaccine
Poliomyelitis (shortened to polio) has been around for thousands of years, and there is still no cure, but at the peak of its devastation in the United
States, Dr. Jonas Salk introduced a way to prevent it. Polio attacks the nerve cells and sometimes the central nervous system, causing muscle wasting,
paralysis, and even death. The disease, whose symptoms are flu like, stuck mostly children, and in the first half of the 20th century the epidemics of
polio were becoming more devastating. Salk, while working at the Virus Research
Lab at the University of Pittsburgh, developed a polio vaccine, and the medical trials to prove its effectiveness and safety are still being analyzed. Fifty
years ago the largest medical experiment in...show more content...
The use of the dual protocol illustrates both the power and the limitations of randomized clinical trials. The control trials with the placebo were
important to define the vaccine as the product of scientific medicine, while the observed trials were done to maintain public support for the vaccine. In
1953, Salk presented his tests of a polio vaccine to the Immunization
Committee, the scientific advisory committee for the NFIP. The test results seemed promising to Basil O'Connor, as the children had shown no ill
effects and the levels of polio antibodies in their blood had risen. However, several of the senior virologist on the committee questioned the relation of
antibodies to permanent immunity. Despite the virologist's critique, O'Connor believed that his organization owed it to the volunteers and donors to
proceed and called for the planning of a major field study. O'Connor, in November of 1953, announced that the field trials would begin in the spring and
the observed plan would be used. Within a month, health departments in 38 states had responded, enthusiastic about the prospect of a vaccine. A few
state officials however, questioned the impartiality of the evaluation run by the foundation, and not by scientists.
Responding to the criticism O'Connor called an meeting of an advisory group to review the statistical design. When the group convened, it had decided
to go strictly with the placebo controlled

Research Paper On Polio
By 1910, a small epidemic of polio became regular especially in cities during the summer months. The disease was later called infantile paralysis,
based on its tendency to affect children. Polio is caused by one of three types of poliovirus. These viruses spread through contact between people, by
nasal and oral secretions, and by contact with contaminated feces. Poliovirus enters the body through the mouth, multiplying along the way to the
digestive tract, where it further multiplies. About 95% of all cases display no symptoms. When symptoms appear they are flu–like symptoms that last
for a few days or weeks, such as fever, sore throat, headache, vomiting, back and neck pain, arm and leg stiffness, muscle tenderness, and muscle
spasms. Polio is often recognized because of symptoms...show more content...
The 1952 polio epidemic became the worst outbreak, of the nearly 58,000 cases reported 3,145 died and 21,269 were left with mild to disabling
paralysis. Three years later, Dr. Jonas Salk from The University of Pittsburgh, became a national hero when he developed the first safe and effective
polio vaccine in 1955 with the support of the March of Dimes. In the two years before the vaccine was, widely available, the average number of
polio cases was more than 45,000. By 1962, that number had dropped to 910. By 1979, the virus had been completely eliminated across the country.
There is no cure for polio once a person becomes infected. Therefore, treatments include antibiotics, pain killers, ventilators to help breathing, and
moderate exercise. The disease can kill and remains incurable, but vaccines have assisted in almost total eradication in the world. Polio vaccination in
the United States is still recommended because of the risk of imported cases, children are recommended to receive the inactivated polio vaccine at 2
months and 4 months of age, and then twice more before entering elementary

Polio Virus Essay
Polio Virus
Introduction
The polio virus which causes poliomyelitis in humans is an enterovirus which belongs to the picornavirus (small, RNA) family. Polio virus is rapid,
acid–resistant, stable, highly tissue specific and consists of a single–stranded, positive RNA. Polio virus is able to reside in the throat or intestinal tract
of humans. Poliomyelitis is a highly contagious infectious disease which has three strains, poliovirus 1 (PV1), PV2 and PV3. Polio virus, although rare
in developed countries, can be found in many under–developed countries due to the uncommonness of vaccinations there. Polio is known as a disease
of development. The oldest known record of polio is in an Egyptian stone engraving of a young priest from 1350...show more content...
Receptor–mediated endocytosis is thought to take the receptor into the cell. Polio virus is tissue tropic, meaning it replicates only in specific tissue
types, generally lymphoid tissue in the pharynx and intestine. After uncoating, polio virus, which is an RNA virus, takes a single RNA molecule in its
protective capsid. This RNA can be converted directly to a protein in the cytoplasm. The virus must then replicate its RNA using viral RNA–directed
RNA polymerase. After replication of its own RNA, the virus must package the new RNA into capsids in order to infect more cells.
Transmission
After replication in the mouth and intestine, polio virus spreads through the body via the blood. Polio virus is contained in the Peyer's patches of the
small intestine. Transmission to the central nervous system and neuronal cell destruction is seen in a small number of infected individuals.
Damage
Polio virus affects humans by a lytic cycle. PV1 which is usually associated with epidemics causes paralysis and consequently the most deaths. PV2
normally causes meningitis and a less severe paralysis. PV3 is usually associated with sporadic cases of polio virus. The majority of polio cases
include only diarrhea symptoms or the individual is completely asymptomatic. Five percent of polio cases show flu–like symptoms of fever, malaise,
headache, nausea, sore throat, upset stomach, and achy muscles. In one percent of

population. Polio virus is most commonly found in area with low standards of sanitation. It spreads through faecal–oral transmission or through
contaminated food and water. The polio virus works by replicating the motor neurons in the CNS and then destroying the original motor neuron cells.

In cases of non–paralytic polio, the body doesn't become paralytic but, there may be acute stiffness in the arms and legs. Non–paralytic polio may
include symptoms like; fever, sore throat, headache, nausea and vomiting, fatigue, pain in the back and neck, stiffness in the arms and legs, muscle
tenderness, spasms and in some of the worst cases meningitis which is an infection of the membranes surrounding the brain. There are three types of
paralytic polio, spinal, bulbar and bulbospinal. Spinal Polio attacks the motor neurons in the spinal cord which results in paralysis in the arm and
legs, it can also cause breathing problems. Bulbar Polio affects the medulla oblongata, a muscle in the brain responsible for breathing, heart rate. It can
lead to problematic health issues such as poor eyesight, difficulty in swallowing and respiratory issues like breathing problems. Bulbospinal Polio
includes both the symptoms spinal and bulbar polio. There are also cases of Post–Polio Syndrome which is a cluster of symptoms that affect up to
50% of all polio patients. On average, the syndrome occurs 35 years after the infection. Symptoms of post–polio syndrome include; muscle and joint
pain that progress throughout the body, muscle atrophy which is shrinking muscle volume, unexplained exhaustion and swallowing and breathing

Polio Research Paper
Polio is an infectious disease caused by a special types of viruses. The United States Of America is still at risk of introducing polio. A polio like illness
has recently been discovered in California in children that produces paralysis like in some polio patients. The last case of polio in The United States Of
America was in 1979. Polio is still a very high problem in Africa and Asia. Polio has also been traced back almost 6,000 years ago.
Polio is caused by small viruses, RNA viruses to be exact. The viruses are members enterovirus group of the Picornavirus family. The polio virus is
known to attack the nervous system. There are 3 different types of polio viruses. Type one is responsible for about 85% of all paralytic infections.

One of the main symptoms is muscle weakness and/or tiredness. Another symptom would be vomiting. Another symptom is fatigue Also another
symptom can possibly be joint pain. The rest of the symptoms are headaches, nausea, fever, and sore throat.
If you already have polio there is no cure for it. If you take polio prevention vaccines. There are three different types of vaccines. If you take theses
vaccines the viruses could mutate. If the virus mutates to where the vaccine doesn't work polio can possibly kill you even faster. You mainly want to
make sure that your kids and parents are vaccinated because they are most likely to get polio and not survive.
Here are a couple more facts about polio that you might not know. Up to 90% of polio cases don't even have symptoms. One in two–hundred people
get paralysis from this disease. Five to ten percent of paralyzed patients die. The viruses is found in saliva and feces of all of the patients that have
polio. Children five and under makeup for 50% of the polio cases but any age of people can get polio. Polio cases have decreased more than 99% since
1988. Polio went from having three–hundred and fifty thousand to only four hundred and sixteen. The first polio vaccine was made by Jonas Salk in
1952 to try to prevent polio since there is no

The similarity between the poliovirus and already solved plant virus's led to a better understanding of how the poliovirus can regenerate within a host.
Although the virus was similar to other plant viruses. The poliovirus was covered with more elaborate loops that are the site of monoclonal antibody
escape mutations (Hogle, Chow and 229: 1358–1365Filman, Science). Individual proteins of the virus particle are produced by proteolytic cleavages
from a larger precursor, yet the amino and carboxy–termini produced by proteolysis are very distinct. By noting this, Hogle and his team were able to
conclude that proteolysis was not just making a lot of proteins from one gene, it is also controlling the timing of assembly (Hogle, Chow and Filman,
Science 229: 1358–1365).
B. Signs and Symptoms: Approximately 95 percent of people who are infected with poliovirus will not have any symptoms, however, people who are
infected and do not have any polio indicators can still spread the poliovirus. People who become infected with the poliovirus can start having
symptoms as soon as four days after being infected, and not have any symptoms for as many as thirty five days. This time period between infection and
experiencing symptoms is referred to as "The Incubation Period," which is when the virus begins to multiply within the cells that line the back of the
throat, nose, and intestines("Signs and symptoms of Polio." eMedtv.com. Clinaero Inc., 2006–2012. Sunday 4–22–12). For the

Polio Summary
Polio was a deadly disease that struck the United States hard with various epidemic breakouts throughout the country. There are many books written
about the disease and how it was controlled. Polio is a well–researched topic in today's medical world but in this book, Heather Green Wooten, takes it
one step further. She placed the focus of the book in the south, a place where the disease struck almost last yet it claimed many lives. It specifies on
the state of Texas. In addition to that, she combined the disease epidemic with the social and economic development of the state in the twentieth
century. The book follows a well–organized chronological order stating by the early cases of polio and its spread. Then it talks about Franklin D...show

The purpose of the chapter is to provide the readers with some background information. Along with this, it also shows how panic overtook the
American communities. The uncertainty of what the virus was or where it came from caused a paranoia in many cities. The initial reaction was
to quarantine victims and keep them away from the general public. The spread of the epidemic from northern states to Texas is accredited,
according to Wooten, by the mass immigration into Texas by residents of other states during the oil industry's boom in Texas in the early twentieth
century. This exposed many people to polio as they moved into cities and the coastal area of Texas became more and more urbanized. The high
standards of American hygene made polio a death threat. The body did not have the ability of fighting a small dose of the disease as new born did
when hygene in the country was not so clean. By not being exposed to the virus the body did not produce the adequate antibodies to fight it off.
When it struck at a later age the body was defenseless and so the epidemic started. The result of the urbanization of Texas and the many polio
outbreaks helped the area create many hospitals and lead the fight against polio. The book also highlights the life of Franklin D. Roosevelt, who also
suffered of polio. Wooten describes how the president acquired the disease and

The discovery of the polio vaccine was an important medical and scientific breakthrough because it saved many lives since the 1950s. In the summer
of 1916 the great polio epidemic struck the United states. By the 1950s hundreds of thousands of people had been struck by the poliomyelitis. The
highest number of cases occurred in 1953 with over 50,000 people infected with the virus. When hygienic conditions were poor polio attacked infants.
The disease was spread by contaminated water and contact with fecal contamination. Many infants died when the conditions were poor. But as
conditions improved the virus spread differently. It was spread more through playmates and family members, the contamination came from the...show

Dean William McEllroy talked Salk into joining the university full–time. Though the school's research budget was a grant from the American Society
for the Study of High Blood Pressure in the amount of $1,800, he saw the opportunity to do two things. One was to continue the work he was
doing on influenza, second was to begin working with the polio virus. A few months after arriving in Pittsburgh, Salk was visited by the director
of research at the National Foundation for Infantile Paralysis. The director asked Salk if he would be willing to participate in a polio typing
program. "I had no experience working with polio, but it provided me with an opportunity. . ." Salk said in an interview. This gave Salk a chance to
get funding, equipment, a laboratory facility, and to hire a staff to work for and with him. Salk's previous work gave him the idea that a killed virus
could in fact work when others thought it couldn't. To type the polio virus Salk infected monkeys with polio by injecting it into them or feeding it to
them. If a monkey survived it built up antibodies to protect against the virus. The monkeys that survived were then given another type of virus to see if
the same antibodies protected against the second type. If it did, it told Salk and his assistants that the two types were related. If it did not, that told Salk
that they were not related. Eventually
