The American health charity March of Dimes was founded as the National Foundation for Infantile Paralysis to help raise money for polio research.

March of Dimes is a United States nonprofit organization that works to improve the health of mothers and babies. The organization was founded by US President Franklin D. Roosevelt in 1938, as the National Foundation for Infantile Paralysis, to combat polio. The name "March of Dimes" was coined by Eddie Cantor as a pun on the newsreel series The March of Time. After funding Jonas Salk's polio vaccine, the organization expanded its focus to the prevention of birth defects and infant mortality. In 2005, as preterm birth emerged as the leading cause of death for children worldwide, research and prevention of premature birth became the organization's primary focus.

Poliomyelitis, commonly shortened to polio, is an infectious disease caused by the poliovirus. Approximately 75% of cases are asymptomatic; mild symptoms which can occur include sore throat and fever; in a proportion of cases more severe symptoms develop such as headache, neck stiffness, and paresthesia. These symptoms usually pass within one or two weeks. A less common symptom is permanent paralysis, and possible death in extreme cases. Years after recovery, post-polio syndrome may occur, with a slow development of muscle weakness similar to what the person had during the initial infection.
