What happened

Diphtheria was once one of Australia’s most feared childhood infections, killing thousands of children before vaccines were available.

Why it matters

Then for decades, it became so rare most doctors never saw a case.

Common ground

Diphtheria has reappeared in parts of Australia, with cases reported in the Northern Territory, Western Australia, South Australia and Queensland.
