Whooping Cough Cases Surge in Australia: What You Need to Know About Vaccination and Risks
Updated June 10, 2025
Australia is grappling with a significant surge in whooping cough cases, also known as pertussis, with numbers exceeding typical epidemic levels.While whooping cough circulates regularly in Australia, the current outbreak, which began in 2024, has prompted concern among health officials.
In 2025, over 14,000 cases have already been reported, with regions like Queensland and Western Australia’s Kimberley experiencing notable increases. In 2024, Australia recorded over 57,000 cases, the highest annual total since 1991, including 25,900 in New South Wales.
Several factors contribute to this surge. COVID-19 lockdowns in 2020 and 2021 reduced natural immunity and disrupted vaccination services.The United States is also experiencing a surge, with cases at their highest as 1948.
Vaccine coverage in Australia, while relatively high, has dipped below the 95% national target, impacting infection rates. Niall Johnston, a conjoint associate lecturer at UNSW Sydney, and colleagues Helen Quinn and Phoebe Williams have highlighted the importance of maintaining high vaccination rates.
Young babies, especially those under six weeks, face the greatest risk from whooping cough, as they are too young to be vaccinated. infants under six months are also more likely to require hospitalization and may experience severe complications. Though, in 2024, over 70% of cases occurred in children 10 and older, and adults.
While the whooping cough vaccine is effective, its protection wanes over time. Booster doses at 18 months and four years are crucial for maintaining immunity. Adults who want to reduce their risk should also receive a booster, especially those caring for infants. Health care workers and early childhood educators should get a booster every ten years.
Vaccination during pregnancy is highly recommended to protect newborns. If a woman hasn’t been vaccinated during pregnancy, she should be vaccinated after delivery.
Whooping cough is highly contagious, even more so than the flu. Vaccinated individuals may experience milder symptoms but can still spread the infection. Siblings are a common source of infection for babies, emphasizing the importance of timely vaccination for all close contacts.
Early symptoms resemble a cold, but the cough worsens after a week, frequently enough with a “whoop” sound. Infants may experience breathing cessation or turn blue. Teens and adults may only have a persistent cough. Individuals with whooping cough are infectious for up to three weeks unless treated with antibiotics.
To reduce your risk, check your vaccination record, get a booster if pregnant or caring for infants, and consult your doctor if you have a persistent cough.
What’s next
Continued monitoring of whooping cough cases and sustained efforts to improve vaccination rates are essential to controlling the current surge and protecting vulnerable populations. Public health campaigns emphasizing the importance of booster doses and vaccination during pregnancy can further mitigate the impact of this highly contagious disease.
