Dr Anthea Katelaris, Acting Director, South Eastern Sydney Public Health Unit, said anyone who was in the same locations as the cases should be alert for signs and symptoms of measles until August 7.
“It can take up to 18 days for symptoms to appear after an exposure, so it is really important to stay vigilant if you’ve been in the above locations,” Dr Katelaris said in the NSW Health statement.
“If you develop symptoms, please call ahead to your GP to ensure you do not spend time in the waiting room with other patients.”
Measles is highly contagious and is spread in the air through coughing or sneezing by someone who is unwell with the disease.
The viral illness causes fever and rashes but can cause serious complications, including pneumonia and encephalitis.
While measles is rare in Australia due to vaccination programs, it remains common in many parts of the world, with large outbreaks currently occurring in a number of locations.
Measles has also been reported in other states in recent weeks.
People returning from recent overseas travel should be alert for symptoms.
