Measles Surge: Australia's Immunity Below 95% Amid Travel

Health authorities nationwide are on high alert due to a sharp increase in measles cases. In 2025, Australia recorded 168 measles cases, a near threefold rise from the 57 cases observed in 2024. This surge is attributed to a decline in childhood vaccination rates, with national coverage for two-year-olds now at 89.7%, falling below the 95% needed for herd immunity.

The rise in infections coincides with increased international travel during the summer holidays. A significant "Boxing Day cluster" emerged, believed to have originated from a single traveler, leading to alerts in New South Wales and South Australia. This cluster has also impacted Western Australia and Victoria, underscoring the contagious nature of the airborne virus.
