"Many adults don't realise they have whooping cough, but can still spread it. People with a cough should, if possible, try and avoid contact with young babies."
On-time immunisation is the best way to help protect babies, children, pregnant women and adults from whooping cough. Protection for babies begins in pregnancy with free immunisation for pregnant women between 28 and 38 weeks of pregnancy.
"By getting immunised each pregnancy, you pass on your immunity to your baby. This helps protect them from birth until their first immunisation at 6 weeks old," Dr Murray said.
"It is really important that babies get their first immunisation on time at 6 weeks. If immunisation is delayed, they are more at risk of catching whooping cough from others."
After the 6 week immunisation, further free childhood immunisations are required for ongoing protection.
Contact your family doctor to check whether you, your baby and other family members are up to date with whooping cough and other immunisations and make an appointment if needed.
