Measles Alert Issued After Traveler Arrives in Sydney

Authorities in Sydney, Australia, have issued a health advisory following a confirmed measles case entering the city. This announcement urges vigilance among those who may have been exposed to the virus at the international airport.

Exposure Points Identified

The New South Wales (NSW) health department confirmed the individual arrived from Southeast Asia, where measles outbreaks are ongoing. The infected person landed in Sydney on Monday.

People on Vietnam Airlines flight VN773, which arrived at Sydney International Airport on Monday, are advised to watch for symptoms. Individuals in the arrivals and baggage claim areas between 8:00-9:30 a.m. on the same day should also monitor their health.

Mitchell Smith, the acting director of Public Health for the South Western Sydney Local Health District, stated that initial symptoms can include fever, sore eyes, runny nose, and a cough. A rash spreading from the face follows some days later.

“It is important for anyone who was on the flight or in those areas of the airport to monitor for symptoms for 18 days.”

According to the CDC, measles can spread quickly through coughing and sneezing, even before symptoms appear. A recent report indicates a rise in measles cases, with the United States seeing a 1,000% increase in the last year (CDC 2024).

Rising Measles Cases

The National Notifiable Disease Surveillance System recorded 80 confirmed measles cases in Australia during 2025. There were 57 cases in 2024 and 26 in 2023.

This health alert emphasizes the need for prompt action among those potentially exposed to the virus in Sydney. They must monitor themselves for symptoms within the specified timeframe.
