Does polio affect the immune system?
One way the human immune system protects itself is by producing antibodies that engage the protein covering of the poliovirus, preventing the virus from interacting with another cell..
How does polio kill?
Polio can result in permanent disability. Polio can also cause death, usually by paralyzing the muscles used for breathing. Polio used to be very common in the United States. It paralyzed and killed thousands of people every year before polio vaccine was introduced in 1955.
Can polio cause problems later in life?
Symptoms vary from mild, flu-like symptoms to paralysis and possibly death. People who have had polio may experience effects later in life called the late effects of polio. The late effects of polio are when physical symptoms return 15 years or more after the first polio infection.
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 caused the polio virus?
What causes 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 you be cured of polio?
Failure to eradicate polio could result in as many as 200 000 new cases every year, within 10 years, all over the world. There is no cure for polio, it can only be prevented. Polio vaccine, given multiple times, can protect a child for life.
What famous person had polio?
President Franklin D. RooseveltAmong the famous survivors of polio are President Franklin D. Roosevelt, who contracted polio in 1921 at the age of 39 and used a wheelchair thereafter, though he attempted to hide his paralysis during public appearances.
Can you catch polio twice?
Does past infection with polio make a person immune? There are three types of polio virus. Lifelong immunity usually depends on which type of virus a person contracts. Second attacks are rare and result from infection with a polio virus of a different type than the first attack.
What is the key symptom of polio?
Paralysis is the most severe symptom associated with polio, because it can lead to permanent disability and death. Between 2 and 10 out of 100 people who have paralysis from poliovirus infection die, because the virus affects the muscles that help them breathe.
How is polio treated today?
Once the virus that causes polio has infected a person, there is no treatment that will cure polio. Early diagnosis and supportive treatments such as bed rest, pain control, good nutrition, and physical therapy to prevent deformities from occurring over time can help reduce the long-term symptoms due to muscle loss.
Can you walk after polio?
Polio often paralyzed or severely weakened the legs of those who contracted the disease. Regaining the ability to walk was thus a significant measure of recovery from the disease. However, walking meant more than the physical act itself.
How many polio survivors are still alive?
The World Health Organization estimates that 10 to 20 million polio survivors are alive worldwide, and some estimates suggest that 4 to 8 million of them may get PPS.
How old is the oldest polio survivor?
Loraine Allen may be the oldest survivor of polio in the U.S. Allen is 97.
Can you get polio from swimming?
We now know that polio is spread through a fecal-oral contact route, and almost always through contaminated water. The adoption of modern plumbing, sewer systems and water treatment facilities in the late 1800s and early 1900s meant that infants were far less likely to be exposed to polio during the early ‘safe’ phase.
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.
