Whooping cough cases have surged to an unprecedented high, reaching a 35-year peak, according to experts. This alarming trend is attributed to a significant decline in childhood vaccination rates in Australia, which has potentially dire consequences. The Australian Centre for Disease Control's data reveals a staggering 57,257 confirmed cases in 2024, with a concerning 37,663 of these cases affecting infants and children up to 14 years old. This spike marks the highest yearly count since 1991. The situation is particularly dire in NSW and Queensland, where nearly 26,000 and over 15,000 cases were detected, respectively. In 2025, authorities confirmed an additional 25,272 notifications. Whooping cough, caused by the bacterium Bordetella pertussis, can be fatal and leads to prolonged, severe coughing fits. Common symptoms include a runny nose, sneezing, and a mild dry cough in the initial week, followed by heavy coughing episodes after two weeks. Archana Koirala, a paediatrician, links the 2024-25 surge to COVID-19 pandemic restrictions, which limited bacterial spread but also deprived immunized children of the usual immune boost. The decline in vaccination coverage across Australia has led to waning immunity among those who were vaccinated and a delay in vaccine administration for some. This situation creates a 'perfect storm' for outbreaks. Routine childhood immunizations in Australia protect against diseases like hepatitis B, diphtheria, pertussis, polio, rotavirus, measles, meningococcal, and influenza. Paul Griffin, director of infectious diseases, emphasizes the dire consequences of declining vaccination rates, warning that population susceptibility and risk increase, and vaccine-preventable diseases may become more prevalent. In 2024, vaccination rates for one-year-olds, two-year-olds, and five-year-olds fell short of the national target of 95%, with the lowest coverage rates since 2014, 2015, and 2016, respectively. Dr. Koirala highlights the coincidence of declining vaccination rates with an increase in measles cases, with 181 confirmed cases in 2025, up from 57 in the previous year. If vaccination rates don't improve, Australia risks a re-emergence of diseases like endemic measles, a significant concern given the country's success in eliminating constant local transmission in 2014. Catherine Hughes, a vaccine advocate, shares a personal tragedy, losing her son Riley to whooping cough at 32 days old. She laments the decline in childhood vaccination rates and warns of the dangers of misinformation and 'anti-vaccine propaganda' on social media, which can have devastating consequences.
