WA Health has issued a warning regarding two new measles cases linked to a cluster in the Perth and Pilbara region, urging travelers to ensure they are vaccinated.

The alert follows the detection of these two new cases, which involve a BHP worker and a Qantas crew member, stemming from three original cases identified in July 2025.

Clare Huppatz, the acting director of the Communicable Disease Control Directorate, highlighted the high infectiousness of measles, particularly for non-immune individuals working in regional mine sites.

The measles vaccine is available at no cost for anyone born after 1965, with individuals aged 30 to 60 years being particularly at risk due to lower vaccination rates.

Early symptoms of measles include fever, tiredness, cough, runny nose, and sore eyes, followed by a red non-itchy rash that typically appears three to four days later.

People who visited any of the new exposure sites during the specified times are advised to monitor for symptoms for 7 to 18 days post-visit.

New exposure sites include various locations in Morley, Rockingham, and Mandurah, as well as flights between Bali and Perth.

Individuals are encouraged to check WA Health for the latest exposure sites, including flights from Perth to Bali.

Fly-in-fly-out workers in Western Australia are particularly urged to get vaccinated against measles following the recent cases.

Dr. Huppatz encourages anyone aged 30 to 60, whether traveling for work or holidays, to verify their vaccination status against measles.

International travel remains the most likely source of measles, with the 30 to 60 age group identified as the most at risk due to their lower vaccination rates.
