If you visited the Formula 1 Grand Prix last weekend, you could be at risk of exposure to measles following the confirmation of a case in one attendee.

A woman in her forties – who contracted the virus in the Northern Territory – is currently isolated and receiving treatment in hospital.

She attended the Grand Prix in Albert Park on Saturday March 16, where she visited the Jones Stand, the food areas at Gate 1 and the Gate 2 entrance. She returned to the event on Sunday March 17, visiting the Fangio Stand, the food areas at Gate 1 and the Gate 2 entrance.

She also visited the Woolworths supermarket in Braybrook on Sunday between 12pm and 1pm and on Monday March 18 between 1pm and 2pm.

"Anyone who is unvaccinated is at highest risk of contracting measles. People need to have received two doses of measles-containing vaccine to be fully protected,” said Victoria’s chief health officer Dr Brett Sutton in a statement. “Many adults have only received one vaccine against measles and therefore most cases are in this age group. Most people born before 1966 will have been exposed to measles in childhood, and therefore will be protected.”

In January, a person carrying the virus was found to have visited several Melbourne locations including Blackhearts & Sparrows in North Fitzroy and Colonel Tan’s at Revolver Upstairs. And last month another case was reported in a person who visited Southbank and Melbourne Airport.

The Department of Health is advising people to be aware of symptoms, which including rash, fever, conjunctivitis and severe coughing. If you experience symptoms, visit your GP.
