"The Northern Territory and Western Australia are experiencing outbreaks of an
almost-eradicated infection, diphtheria.

The NT has recorded 17 cases of respiratory diphtheria in the past month and 60
cases of the less serious cutaneous diphtheria, affecting the skin, in the past
year.

In the Kimberley region of WA, 27 cases have been reported in the past month
alone, with one-quarter of those respiratory infections.

Cases have also been found in Queensland (two) and South Australia (one) this
year.

Historically, diphtheria was a leading cause of childhood death globally. More
than 4,000 Australians died from diphtheria between 1926 and 1935.

Vaccination started in Australia in the 1930s and the disease has rarely been
seen since the 1950s.

But vaccine coverage has waned since the COVID pandemic, leading to a rising
number of cases."
