Those on flight OD195, a connecting flight from Perth to Auckland, have been asked to monitor for typical symptoms which can include a runny nose, fever and cough.

Passengers are asked to call their usual health provider for testing and treatment, as well as to stay away from pregnant people or babies if they’re unwell with typical whooping cough symptoms.

Those who find themselves having difficulty breathing are urged to contact 111.

People can start developing symptoms anytime in the two to three weeks from exposure.

Te Whatu Ora medical officer of health, Dr Michael Hale said the illness is especially dangerous for babies, young people and those who are pregnant.

Hale said the illness can become unpredictable in young children and babies, who can become very sick very quickly.

“While the risk for most passengers on the flight was low, we are keen to make sure those who could become very sick from whooping cough are alerted to the risk and know the signs to look out for,” he said.

Most people exposed to the illness will find their symptoms develop seven to 10 days after exposure, they’ll find their cough grows worse and they can experience long coughing attacks for up to 12 weeks.

In babies and young childen, the attacks often end with a “whoop” sound at the intake of break - hence the illness’ name.

Hale urged the public to consider getting immunised against the illness, which is the best way to protect against the sickness.

“If you are not sure if you or your child are up to date with immunisations, check with your GP or your practice nurse,” he said.

“Immunising against whooping cough during pregnancy is 90 per cent effective in protecting babies in their first few weeks of life.”
