Where did polio originally come from?
1894, first outbreak of polio in epidemic form in the U.S. occurs in Vermont, with 132 cases. 1908, Karl Landsteiner and Erwin Popper identify a virus as the cause of polio by transmitting the disease to a monkey.
What animal did polio come from?
The discovery by Karl Landsteiner and Erwin Popper in 1908 that polio was caused by a virus, a discovery made by inoculating macaque monkeys with an extract of nervous tissue from polio victims that was shown to be free of other infectious agents.
What was cause of polio?
Polio is caused by the poliovirus. The virus enters the body through the mouth. It is spread through contact with the feces (stool) of an infected person or through exposure to phlegm or mucus when an infected person coughs or sneezes.
Can polio be passed down genetically?
No. Post polio syndrome is not inherited .
Where is Polio most common?
Polio remains endemic in two countries Afghanistan and Pakistan.
Does polio have a vaccine?
Inactivated polio vaccine (IPV) is the only polio vaccine that has been given in the United States since 2000. IPV is given by shot in the leg or arm, depending on the patient’s age. Oral polio vaccine (OPV) is used in other countries. CDC recommends that children get four doses of polio vaccine.
What type of virus is polio?
Polio is caused by a human enterovirus called the poliovirus. Polio can interact in its host in two ways: Infection not including the central nervous system, which causes a minor illness with mild symptoms. Infection including the central nervous system, which may cause paralysis.
Can you recover from polio?
People who have milder polio symptoms usually make a full recovery within 1–2 weeks. People whose symptoms are more severe can be weak or paralyzed for life, and some may die. After recovery, a few people might develop “post-polio syndrome” as long as 30–40 years after their initial illness.
What does Polio do to legs?
Symptoms vary from mild, flu-like symptoms to life-threatening paralysis. In less than 1% of cases, polio causes permanent paralysis of the arms, legs or breathing muscles. Between 5 and 10% of people who develop paralytic polio will die. Physical symptoms may return 15 years or more after the first polio infection.
What three countries still have polio?
Only three polio-endemic countries (countries that have never interrupted the transmission of wild poliovirus) remain—Afghanistan, Nigeria, and Pakistan.
Does polio still exist 2020?
Wild poliovirus has been eradicated in all continents except Asia, and as of 2020, Afghanistan and Pakistan are the only two countries where the disease is still classified as endemic.
How long do polio survivors live?
For years, most polio survivors lived active lives, their memory of polio mainly forgotten, their health status stable. But by the late 1970s, survivors who were 20 or more years past their original diagnosis began noting new problems, including fatigue, pain, breathing or swallowing problems, and additional weakness.
Why does Pakistan still have polio?
By 1991, only 83 percent of Pakistani children had been vaccinated. Research by the Center for Disease Control (CDC) in April 1998 cited a failure to vaccinate, vaccine failure, and inadequate immunization strategies as causes for the continued incidences of polio in this time.
