Imagine a fatal disease that you could not see, touch, cure, or hear. This deadliest disease is known as the polio virus. The polio virus causes paralysis of the arms, legs, and chest muscles. The disease used to be called “infantile paralysis”, because it was most common in children. Many could no longer walk again without the use of leg braces. Others could not breathe without the help of machines. This disease caused terror all over the world. People couldn’t figure out how it came about, who the victims would be, or how to cure it. Today, polio does not exist because of the incredible discovery of the polio vaccine. Jonas Salk freed the world from the deadly disease and the fear that encompassed it.
