	Poliomyelitis - Wikipedia, the free encyclopedia
		Polio (infantile paralysis) is a communicable disease which is categorized as a disease of civilization.
		On May 5, 2005, news reports broke that a new case of polio was diagnosed in Java, Indonesia and the virus strain was suspected to be the same as the one that caused the outbreak in Nigeria.
		The polio victims have in their daily trips (one or two) a means of life with more dignity than begging, and that involves them in the community life instead of being outcasts.

	Polio Facts
		Polio is diagnosed by a blood test or culture.
		Polio is most common in infants and young children, but complications occur most often in older persons.
		Wild polio is naturally circulating polio that is not caused by the oral polio vaccine.

	Polio vaccine - Wikipedia, the free encyclopedia
		Though Salk's vaccine had reduced the incidence of polio to a tiny fraction of what it was in the early 1950s, Sabin's vaccine was considered superior for these reasons and became the standard treatment.
		In the United States, once polio was eradicated within its population, the Centers for Disease Control decided that the slight advantages of the live-virus vaccine were not worth several vaccine-induced cases of polio each year.
		The two vaccines have eliminated polio from most of the countries in the world and reduced early cases from hundreds of thousands per year to only 1000 worldwide in 2001.

	HHMI's BioInteractive - Featured Infectious Disease: Polio
		Polio has already largely been relegated to the history books in the United States—although many people who had contracted polio in childhood suffer the muscle pain and weakness of postpolio syndrome.
		Polio has existed for thousands of years, but it wasn't until 1908 that two scientists showed that paralytic polio is a contagious viral disease.
		For much of this century, and especially before the discovery of the polio vaccine in the 1950s, polio was a much-feared illness, causing major epidemics in 1910 and 1916 and in the 1930s, 1940s, and 1950s.

	Polio Definition
		Polio, or more properly poliomyelitis, was one of the most feared and studied diseases of the first half of the 20th Century.
		This is probably due to the fact that as polio epidemics ended in North America and Europe, research on the disease also came to an abrupt halt.
		The belief that the polio virus is spread by contact with the feces of an already infected person has been offered as an explanation for the increased incidence of polio in developed countries such as the United States during the 20th Century.

	Dr. Koop - Post-Polio Syndrome- Health Encyclopedia and Reference
		Polio, also known as poliomyelitis or infantile paralysis, is caused by three viruses that enter the mouth, grow in the intestines and pass along the nerves into the brain and then the spinal column causing the nerves to stop working normally.
		Polio was eradicated in the 1950s with the introduction of the polio vaccine developed by Jonas Salk.
		Mandatory immunization for polio is recommended at 2 months of age, 4 months of age, 6 to 18 months age, and 4 to 6 years of age.

	Information About the Late Effects of Polio (Site not responding. Last check: 2007-10-21)
		Survivors who had polio as children may have no conscious memory of the illness or subsequent rehabilitation, whereas some survivors vividly remember the pain and paralysis of the acute infection and their medical treatments.
		Polio survivors can have feelings of guilt about being “a burden.” Or, they may feel sadness for “the way things were.” You may feel resentful of your new responsibilities.
		Polio survivors who visit your office may be reporting a variety of neurologic, orthopedic, medical, musculoskeletal, emotional, and rehabilitation complaints, all of which need to be methodically addressed and not dismissed simply as signs of aging.

	Development of Polio Vaccines
		Polio can be spread through contact with infected feces or through infected droplets traveling through the air, in food, or in water.
		Although polio never devastated large numbers of the population like the plague or influenza, it was a frightening, highly contagious disease that attacked both the poor and rich and arose in terrifying outbreaks which seemed impossible to stop in spite of advances in medicine.
		We now know that polio is caused by three strains of quite stable viruses that are a part of the enterovirus family, which have RNA as their genetic material.

	Polio
		Polio (also called poliomyelitis) is a contagious, historically devastating disease that was virtually eliminated from the Western hemisphere in the second half of the twentieth century.
		Although polio has plagued humans since ancient times, its most extensive outbreak occurred in the first half of the 1900s before the vaccination, created by Jonas Salk, became widely available in 1955.
		Polio is transmitted primarily through the ingestion of material contaminated with the virus found in stool (poop).

	Polio - DrGreene.com
		Polio is a disease once widely feared for its ability to strike healthy children without warning, causing paralysis or death.
		Children with polio may develop a fever along with one or more of a variety of symptoms including headache, neck and back pain, sore throat, abdominal pain, constipation, appetite loss, nausea, vomiting, and fatigue.
		Polio should be suspected based on the symptoms — especially with the combination of fever, headache, neck and back pain, and paralysis without loss of sensation.

	Polio definition - Medical Dictionary definitions of popular medical terms
		Polio: Abbreviation for poliomyelitis, an acute and sometimes devastating disease caused by a virus.
		In polio, there is inflammation of the central nervous system, especially the anterior horn cells of the spinal cord and the brainstem (the portion of the brain between the cerebral hemispheres and spinal cord).
		Polio can be a minor illness, as it is in 80-90% of clinical infections, chiefly in young children, and not involve the CNS.

	The polio vaccine (0-12 months)
		Polio has now been eliminated from the Western hemisphere; there has not been a case of natural polio in the United States since 1979 or in the Americas since 1991.
		But outbreaks of polio continue in Africa and Asia, and global travel is common enough that a traveler could easily import polio back to this country.
		No child ever contracted polio from the oral vaccine when it was given as a third or fourth dose, but the government decided the risk of giving this vaccine was still too great, so they took it off the schedule.

	Information about Polio
		In paralytic polio, the polio virus invades the central nervous system -- the spinal cord and the brain -- and may cause weakness, paralysis, serious breathing problems or death.
		Polio is caused by a virus that lives in the throat and intestinal tract.
		Post Polio Syndrome is a 'second' disability affecting a large number of polio survivors.

	Communicable Disease Fact Sheet
		Polio is a viral disease which may affect the central nervous system.
		Polio is more common in infants and young children and occurs under conditions of poor hygiene.
		In exceedingly rare cases, oral polio vaccine has caused paralytic polio in a person who received the vaccine or in a person who was a close contact of a vaccine recipient.

	Polio
		The polio viruses (there happen to be three of them) are from a class known as "enteroviruses", because they usually infect the intestines (at least initially).
		However, the oral vaccine is still used in countries where polio remains prevalent; the risk of getting polio from the vaccine is much less than the risk of catching polio from someone else in those areas.
		Since polio is still prevalent in developing countries, it's sometimes a good idea for adults to receive a booster dose of vaccine (usually IPV, since we don't routinely carry OPV in the United States) before traveling to those areas.

	Vaccine Science: Polio (Site not responding. Last check: 2007-10-21)
		Immunity against polio can be stimulated in one of two ways, either through immunization, when the body attacks the weakened/dead virus and thus grows immune to it, or following natural infection with poliovirus.
		The action of oral polio vaccine (OPV) is two-pronged: OPV produces antibodies in the blood (‘humoral’ or serum immunity) to all three types of poliovirus.
		For this reason, OPV is the vaccine of choice wherever a polio outbreak needs to be contained, even in countries that rely exclusively on IPV for their routine immunization programs (polio outbreak in the Netherlands in 1992).
