Measles alert after infectious people at Oasis concerts

Health authorities have released a full list of exposure sites as cases were also confirmed at a Jelly Roll concert.

A Queensland resident with a confirmed case of measles visited parts of Sydney while infectious, including Accor Stadium for an Oasis concert, NSW Health authorities have warned.

The health alert comes after three cases of measles were confirmed in Queensland associated with the Jelly Roll concert in Brisbane on October 24.

A NSW Health spokesperson said people who attended the Oasis concert at Accor Stadium in Sydney on Saturday should monitor for symptoms until Friday, November 28.

 People who attended the Oasis concert at Accor Stadium in Sydney on Saturday, November 8 should monitor for symptoms until Friday, November 28.

The person also visited the Sydney Airport, the CBD, and inner west locations, and used trains between Saturday and Monday.

A full list of locations is posted on the NSW Health website.

"These locations pose no ongoing risk," NSW Health said.

Queensland Health yesterday issued its own measles alert after three confirmed cases emerged from a concert at the Brisbane Entertainment Centre.

Anyone who attended American singer Jelly Roll's show on October 24 could have been exposed and is urged to be on the lookout for symptoms.

The three people spent time in the Gold Coast, Brisbane and Wide Bay areas while unknowingly infectious, Queensland Health said.

Health Protection NSW executive director Dr Jeremy McAnulty said measles is a vaccine preventable disease that is spread through the air when someone who is infectious coughs or sneezes.

"Symptoms to watch out for include fever, sore eyes, runny nose and a cough, usually followed three or four days later by a red, blotchy rash that spreads from the head and face to the rest of the body," McAnulty said.

"It can take up to 18 days for symptoms to appear after an exposure, so it's important for people who visited these locations to look out for symptoms up until Friday, November 28.

"It's important for people to stay vigilant if they've been exposed, and if they develop symptoms, to please call ahead to their GP or emergency department to ensure they do not spend time in the waiting room with other patients.

"We want to remind the community to make sure they are up to date with their vaccinations.

"This should be a reminder for everyone to check that they are protected against measles, which is highly infectious.

"Anyone born after 1965 needs to ensure they have had two doses of measles vaccine. This is especially important before overseas travel, as measles outbreaks are occurring in several regions of the world at the moment."
