Whooping cough is surging in Australia. Why, and how can we protect ourselves?

Cases are highest in Queensland and New South Wales, with more than 1,000 recorded in each state.

Key Points: 
  • Cases are highest in Queensland and New South Wales, with more than 1,000 recorded in each state.
  • The last time Queensland recorded more than 1,000 cases in three months was the first quarter of 2013.
  • So what is whooping cough, why are cases rising now, and how can you protect yourself?

It’s most dangerous for babies

  • The initial symptoms of whooping cough resemble other cold and flu-like symptoms.
  • However, as the disease progresses into the second week, the coughing fits become worse and more frequent.
  • After or between bouts of coughing, patients may gasp for air and produce the characteristic “whoop” noise.
  • Immunity from these vaccines wanes over time, so it’s also recommended adults receive a booster, particularly those who may come into frequent contact with babies.

Why are cases rising now?

  • Due to COVID measures such as border closures, social isolation and masks, the number of cases declined dramatically during 2020–23.
  • In Australia, cases have been particularly high during this outbreak in children aged 10–14.

A potential superbug

  • Most vaccines used in Australia and other developed countries stimulate your immune system to recognise and target three to five components of the bacteria.
  • These mutations make the bacteria look slightly different to the one used in the vaccine, helping it better hide from the immune system.
  • But in 2008, a new strain appeared in Australia that no longer produced pertactin, one of the components targeted by the vaccine.
  • This means your immune system, like a detective, has one less clue to recognise the bacteria.

What next?

  • Greater tracking of whooping cough strains, like we do with COVID, is needed to inform future vaccine design and treatments.
  • Importantly, although the bacteria is evolving, current vaccines are still very effective at preventing serious disease and reducing transmission.
