Health authorities in New South Wales (NSW) have issued a public alert after a confirmed case of measles was reported in a passenger who travelled through Sydney International Airport while infectious. The traveller, who arrived on Vietnam Airlines flight VN773 from Southeast Asia earlier this week, may have exposed others in the airport’s arrival and baggage claim areas between 8:00 and 9:30 am.
The case comes amid ongoing measles outbreaks in several Southeast Asian countries, health officials said. Authorities are urging anyone who was on that flight or in the airport during that time to stay alert for symptoms and monitor their health until 18 days after potential exposure.
Dr. Mitchell Smith, Acting Director of Public Health for South Western Sydney Local Health District, explained that early symptoms of measles include fever, sore eyes, cough, and a runny nose, followed by a rash that typically starts on the face and spreads to the rest of the body. “If you develop any of these symptoms, especially after possible exposure, seek medical attention promptly,” he advised.
Rising measles cases in Australia
According to Australia’s National Notifiable Disease Surveillance System, the country has already recorded 80 measles cases in 2025, up from 57 in 2024 and 26 in 2023, showing a worrying upward trend. Health experts believe international travel and lower vaccination rates in some regions are contributing to the rise.
Globally, measles remains a serious threat. The World Health Organization (WHO) warns that measles is one of the most contagious viral diseases, spreading easily through coughing, sneezing, or even breathing the same air as an infected person. It primarily affects children and can lead to complications such as pneumonia, brain swelling, or death. In 2023 alone, over 107,000 people, mostly children under five, died from measles despite the existence of a reliable vaccine.
How to stay safe: Preventive measures
- Get vaccinated: Two doses of the measles, mumps, and rubella (MMR) vaccine offer lifelong protection in most cases.
- Check your immunization records before travelling, especially to regions with active outbreaks.
- Watch for symptoms if you’ve been in contact with someone infected or were at the Sydney Airport during the specified time.
- Avoid contact with vulnerable groups like infants, pregnant women, and people with weakened immune systems if you’re unwell.
- Consult a doctor immediately if you show symptoms.
Health authorities explain that vaccination is the most effective defence against measles and urge everyone to ensure their immunizations are up to date.
