Polio and the Iron Lung: A Brief Background
Polio was a widespread infectious disease in the early 20th century, causing paralysis and death in thousands annually. The development of the polio vaccine in the 1950s drastically reduced cases. During the height of polio outbreaks, the iron lung was a lifesaving device used for patients with paralysis affecting breathing. Over time, as vaccination rates increased, the use of iron lungs declined. Martha Lillard’s reliance on the device made her a symbol of the disease’s historical toll in America.
Her death in 2024 represents the last known use of an iron lung in the country, a device that was once common in hospitals across the US.
“Martha Lillard’s passing marks the end of an era in American medicine and reminds us of the importance of vaccination and disease prevention.”
