- •Identified 17 measles cases in NSW since January 1, 2026, prompting the warning.

Health authorities in New South Wales have issued a public health alert for passengers who were at Sydney Kingsford Smith Airport (SYD) and on a specific Jetstar Airways (JQ) flight. The measles alert Sydney Airport warning was triggered after a passenger, later diagnosed with the highly infectious disease, transited through the airport's domestic terminal. This event highlights the critical role of airports in the surveillance and potential transmission of communicable diseases.
According to the New South Wales Health (NSW Health) media release, the exposure occurred at Sydney Airport's Domestic Terminal 2 (T2) on Wednesday, February 18, 2026. The infectious individual subsequently traveled on Jetstar Flight JQ505 from Sydney to Melbourne. The alert is part of a broader response to a recent increase in measles cases, with 17 confirmed cases recorded in New South Wales since January 1, 2026. The latest warning was issued on February 21, 2026, following the identification of two new cases, one of whom was a returned traveller from South-East Asia and the other an interstate traveller.
Exposure Details and Public Health Response
The Public Health Alert issued by Health Protection NSW provides specific guidance for individuals who may have been exposed. Passengers and staff present at SYD Terminal 2 on the specified date are advised to be vigilant for symptoms. The incubation period for measles can be up to 18 days after exposure, meaning individuals may not show signs of illness until early March. Symptoms of measles include fever, cough, runny nose, and sore, red eyes, followed by a characteristic red, spotty rash that starts on the head and spreads to the rest of the body.
NSW Health has emphasized the importance of vaccination as the most effective protection against the disease. The Measles-Mumps-Rubella (MMR) vaccine is recommended for all travellers and is part of the standard childhood immunization schedule in Australia. The recent cluster of cases underscores a trend of imported vaccine-preventable diseases through international air travel, particularly from regions experiencing measles outbreaks.
In an official statement, Dr. Vicky Sheppeard, Executive Director of Health Protection NSW, advised potentially exposed individuals on the correct protocol. "If symptoms develop and you've been at one of the locations at the time listed on the website, see your doctor or health service, including an emergency department," she stated. "Call ahead to let them know that you may have come into contact with measles so you don't spend time in waiting rooms with other patients."
Aviation Industry Implications
Incidents of this nature place significant operational responsibilities on airlines and airport operators. While health screenings are managed by government authorities, airlines are often tasked with assisting in contact tracing by providing passenger manifests. Airports serve as frontline locations for public health surveillance due to the high volume of international and domestic passengers passing through daily. The alert for Sydney Airport, a major international hub, demonstrates how quickly an infectious disease can be transported across state and national borders.
The aviation industry has well-established protocols for managing public health events, developed in coordination with bodies like the World Health Organization and national health departments. These procedures include aircraft disinfection, crew health monitoring, and communication with passengers. The current situation with Jetstar flight JQ505 is a practical application of these public health and aviation safety protocols.

Why This Matters
This public health alert underscores the persistent vulnerability of the global aviation network to the spread of infectious diseases. For airlines and airports, it reinforces the need for robust communication channels with health authorities and effective protocols for passenger and crew welfare. For the travelling public, it serves as a critical reminder of the importance of maintaining up-to-date vaccinations, particularly when travelling internationally, to mitigate personal health risks and prevent wider community transmission.
