Polio Decline and the Role of Iron Lungs in Treatment
Polio was a major health threat in the early 20th century, leading to paralysis and death in thousands of Americans annually. The iron lung was introduced in the 1920s as a life-saving device for severe cases. Widespread vaccination campaigns in the 1950s and 1960s drastically reduced polio cases in the US. The last reported case of wild poliovirus transmission in the country was in 1979. Over time, advances in medical technology and vaccination have made the iron lung obsolete, with only a handful of patients worldwide still using the device, mostly in developing countries.
Ms. Lillard’s reliance on the iron lung persisted into her 70s, making her a rare survivor of the polio era. Her case was well-known among polio survivors and medical historians as the last in the US to depend on this device.
“She lived a full life, and her death marks the end of a significant chapter in medical history.”
— Her son, James Lillard
