In the mid-20th century, a disease that struck without warning turned every parent’s world upside down. Known as infantile paralysis, polio was a terrifying scourge that left thousands of children permanently disabled or dead. Today, thanks to widespread vaccination, it is largely a memory in Australia—but its history is a stark reminder of the fragility of public health.
The terror of polio
Polio, or poliomyelitis, is a highly infectious viral disease that can cause irreversible paralysis. In the 1940s and 1950s, Australia experienced severe epidemics, with summer outbreaks sparking panic. Parents kept children away from swimming pools, cinemas, and playgrounds, fearing the invisible enemy. The disease often struck children under five, but could affect adults too.
A parent’s worst fear
For families, a polio diagnosis meant weeks or months in isolation wards, with no cure available. Many children were left with permanent disabilities, needing leg braces, crutches, or iron lungs to breathe. The emotional and financial toll was immense. One mother recalled, “You’d watch your child struggle to walk, and there was nothing you could do.”
The forgotten disease
With the introduction of the Salk vaccine in 1955 and later the oral Sabin vaccine, polio cases in Australia plummeted. The last naturally occurring case was reported in 1977. Today, polio is often called a “forgotten disease” because younger generations have no memory of its devastation. However, it remains endemic in a few countries, and vaccination campaigns continue globally.
Lessons from history
Public health experts warn that complacency could allow polio to return. The COVID-19 pandemic highlighted how quickly infectious diseases can disrupt society. The story of polio is a testament to the power of vaccines and the importance of maintaining high immunisation rates. As one historian put it, “We owe it to past generations to remember the nightmare they endured—and to protect future ones.”
Today, polio is a footnote in Australian medical history, but its legacy endures in the stories of survivors and the ongoing fight against vaccine hesitancy. The “forgotten disease” may be gone, but it should never be forgotten.
