Health experts warn AFL Grand Final could trigger measles outbreak

Health experts warn that this weekend's AFL Grand Final could trigger a national outbreak of measles, linked to a case that recently returned from overseas. Reigning premiers Brisbane are set to face Geelong at the Melbourne Cricket Ground, with about 100,000 people expected to attend, including roughly 30,000 Lions fans traveling from Queensland to Victoria.

On Thursday, health authorities in Queensland confirmed multiple measles infections in the state. The outbreak is most concerning in Cairns, where a dozen cases have been recorded this month, with additional cases in central Queensland and on the Gold Coast. Officials say the case likely contracted the illness abroad and a public health alert has been issued.

Measles is highly contagious and spreads through coughing, sneezing, talking, or breathing in air contaminated by an infected person. The virus can linger in a room for several hours after the infectious individual has left. Symptoms typically begin with fever, tiredness, cough, runny nose, and red, inflamed eyes, followed by a blotchy red rash.

Dr. Dough Haw, a Metro North Public Health Physician, notes that the incubation period is typically about 18 days from exposure to symptom onset. He and other health officials warn that with around 100,000 people expected at the MCG for the grand final, large gatherings pose a clear risk for transmission.

Professor Paul Griffin, director of infectious diseases, said the highly contagious nature of measles means more cases could emerge in the coming weeks, and there is a risk the infection could spread to Victoria as fans travel for the game. He has been in Melbourne for the weekend match and emphasizes that even brief contact or sharing a room with an infectious person can lead to transmission.

Public health officials urge residents in Queensland and Victoria to check their vaccination status and ensure they are up to date on measles immunization. Vaccination remains the best protection against the disease.

Authorities say they are monitoring the situation and will provide updates as they become available.
