South Eastern Sydney Local Health District Public Health Unit Acting Director, Dr Anthea Katelaris, said the locations pose no ongoing risk but it is important to look out for symptoms.
"Symptoms to watch out for include fever, runny nose, sore eyes 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," Katelaris 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 stay alert for symptoms until Saturday June 29, 2024.
"Anyone who develops symptoms should call ahead to their GP or emergency department and say that they may have measles to ensure they do not spend time in the waiting room with other patients.
"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 to check before overseas travel, as measles outbreaks are occurring in several regions of the world at the moment."
