Measles and diphtheria cases rise in Australia amid falling vaccination rates

Australia, long free of endemic measles, is confronting a new cluster after an overseas-infected traveller introduced the virus to Brighton Secondary School in South Australia, resulting in nine confirmed cases, including a hospitalised adult. Chief Public Health Officer Nicola Spurrier described the development as disappointing but unsurprising given post-pandemic drops in vaccination and anti-vaccine misinformation. Epidemiologist Adrian Esterman highlighted access issues and busy parents as factors behind falling uptake, noting parallel surges abroad in Canada, the UK and the United States.

Concurrently, the country is experiencing its biggest diphtheria outbreak since records began, with over 600 infections, 22 of them in South Australia, predominantly among Indigenous peoples in remote areas. SA Health reports that vaccination campaigns have delivered more than 4,500 doses to affected communities, and the response in the APY Lands has been praised. Officials stress that maintaining high immunisation rates is essential to prevent further resurgence of these once-controlled childhood diseases.
