Quick Summary

Health authorities in South Australia are concerned about recent outbreaks of diseases like measles and diphtheria. A measles outbreak at Brighton Secondary School has brought the total cases for this year to nine, the highest since 2016. The outbreak started with a traveller who contracted measles overseas, leading to three more student infections and one adult case requiring hospitalization. SA's Chief Public Health Officer attributes declining vaccination rates partly to misinformation spread during the pandemic. Meanwhile, Australia is experiencing its largest diphtheria outbreak on record, predominantly affecting Indigenous people in remote areas across four states and territories.

Story summary

In South Australia, a recent outbreak of measles at Brighton Secondary School was sparked by a traveler who contracted the disease abroad. The infected individual spread measles to three other students and an adult in their 40s, who required hospitalization. This resurgence is concerning as Australia had been declared free of endemic measles by the World Health Organisation (WHO) in 2014, indicating no ongoing local transmission but allowing for imported cases.

Australia also faces its largest diphtheria outbreak since records began, primarily affecting Indigenous communities in remote areas across four states and territories. Prior to widespread vaccination, contracting measles was a common childhood experience, with Australia eliminating the disease through a successful vaccine campaign that has maintained endemic measles-free status since late 2014.

These outbreaks highlight the ongoing challenges of maintaining high vaccination rates and the risks posed by diseases reintroduced from overseas.
