How long has polio been infecng people?
Polio has been infecng people for thousands of years. A stone carving from
Egypt dated to about 1500 B.C.E. shows a boy with shrunken legs caused by the
virus. Tiny Tim in Charles Dickens’s A Christmas Carol was probably a vicm of polio.
Polio mainly infects children.
Which U.S. President had polio? When did he serve as President? How old was
he when he contracted polio?
Franklin Delano Roosevelt, FDR, was 39 years old when he contracted polio on
August 10, 1921. He was the 32 nd President. “Once you’ve spent two years trying to
wiggle one toe, everything is in proporon,” Franklin Delano Roosevelt said in 1945.
FDR had paralyc polio, which caused him to be paralyzed from the waist down.
He was the only disabled president. He served as President from 1933 to 1945. He
was the only U.S. President to serve three terms. He died less than three months
aer he was elected to his fourth term. The United States Constuon has since been
changed, so that no one can be elected for more than two terms as President.
Who discovered the polio vaccine?
Polio used to be widespread unl Dr. Jonas Salk, a true American hero,
discovered the polio vaccine. The polio vaccine was made available to the public in
1955. He did not patent his polio vaccine discovery, because it would have drascally
increased the medicine’s price. He freely distributed the polio vaccine so every child
could be saved from contracng this potenally crippling disease. In addion to
polio, Dr. Salk dedicated his life to researching the causes, prevenons, and cures of
influenza, cancer, and AIDS.
