Sydney Measles Alert Issued After Exposure Linked to Overseas Traveller
NSW Health has issued a measles alert in Sydney after confirming a case in a returned international traveller who was infectious while visiting public locations on January 27, 2026. Authorities have advised people who were at Sydney Airport and on selected train services to monitor for symptoms for up to 18 days. Health officials say the exposure sites pose no ongoing risk but stress vaccination remains the most effective protection, particularly for people born after 1965.
NSW Health has issued a measles alert across Sydney after confirming a case in a returned international traveller who was infectious while moving through several public locations. Health authorities are advising anyone who visited the listed exposure sites to remain alert for symptoms and ensure their vaccinations are up to date.
According to NSW Health, the individual arrived in Sydney from Manila on Cebu Pacific Flight CEB39, landing at Sydney International Airport at 10:50 am. The person was present in the international arrivals and baggage claim area between 11:00 am and 12:00 pm. They later travelled on the T8 Airport train line to Central Station, followed by the T1 line to Hornsby Station during the early afternoon.
Exposure risk and health advice
People who were at these locations during the specified times are considered potentially exposed. NSW Health has stressed that the sites do not pose an ongoing risk, but individuals should monitor their health for up to 18 days, which is the maximum incubation period for measles.
Measles is a highly infectious viral disease spread through airborne droplets. Early symptoms commonly include fever, cough, runny nose and sore eyes, with a red rash typically developing several days later. The virus can be transmitted before symptoms appear, making early identification critical.
Dr Vicky Sheppeard, Executive Director of Health Protection NSW, urged anyone who develops symptoms to call ahead before visiting a GP clinic or emergency department to help prevent further transmission. She also encouraged residents to review their immunisation history.
Since 1 December 2025, NSW has recorded 14 confirmed measles cases, many linked to international travel. Health officials warn that the risk of additional cases increases during periods of high overseas travel, particularly when travellers return from regions experiencing outbreaks.
Vaccination remains the most effective protection against measles. NSW Health recommends that people born after 1965 ensure they have received two doses of the measles-containing vaccine. The measles, mumps and rubella (MMR) vaccine is available free of charge in NSW for eligible individuals.
Residents seeking further information about exposure locations or vaccination advice are encouraged to consult NSW Health guidance and remain vigilant over the coming weeks.
