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.
