Health authorities are urging residents of the Fleurieu Peninsula and Kangaroo Island to ensure their families are protected against whooping cough as South Australia experiences a sharp rise in cases of the highly contagious disease. So far this year, 1,349 cases of whooping cough, or pertussis, have been reported across the state—13 times the number recorded at this time last year.

The Fleurieu Peninsula and Kangaroo Island, known for their close-knit communities, are particularly encouraged to act, given the heightened vulnerability of infants and the potential for rapid spread in smaller populations. The disease, which is spread through coughing and sneezing, poses the greatest risk to babies and young children, who can suffer severe complications such as pneumonia, brain damage, and even death.

To combat the surge, health officials are emphasising the importance of vaccination. Free whooping cough vaccinations are available for babies at six weeks, four months, and six months as part of the National Immunisation Program. Pregnant women can also access a free vaccine between 20 and 32 weeks of pregnancy to pass on immunity to their newborns, providing protection until they are old enough for their own vaccinations.

Boosters are available for children at 18 months, four years, and in Year 7 as part of the school vaccination program. Health authorities are also urging parents, grandparents, and anyone who works closely with infants—such as early childhood educators and healthcare workers—to ensure they are up to date with their vaccinations.

“This surge in whooping cough cases is a wake-up call for our community,” says Chief Public Health Officer, Professor Nicola Spurrier. “Vaccination is the best protection, especially for pregnant women and young children. If you’re unsure of your immunisation status, speak to your doctor. It’s also vital to practice good respiratory hygiene, including covering your mouth when coughing, washing your hands, and staying home if you’re unwell.”

For the close-knit and family-focused communities of the Fleurieu Peninsula and Kangaroo Island, ensuring infants and vulnerable individuals are protected is paramount. Recent cases in other states have tragically highlighted the dangers of whooping cough, with Queensland reporting an infant death caused by the disease.

Residents can take proactive steps to safeguard their loved ones by consulting local healthcare providers or their GP to access the free vaccination programs. Those involved in community roles, such as childcare or healthcare, are also advised to get vaccinated to help protect the wider population.

With whooping cough waves occurring approximately every four to five years due to waning immunity, the current rise underscores the need for vigilance. By taking action now, Fleurieu and Kangaroo Island residents can help shield their communities from further spread and protect their youngest and most vulnerable members.
