"The recent cases reinforce the importance of getting vaccinated," she said.
"A highly effective measles vaccine has been freely available for many years and it is vital for everyone, including adults and children, to have two doses of the measles vaccine during their lifetime.
"If you develop the symptoms of measles, seek medical advice. Please call ahead to your doctor or emergency department so that arrangements can be made to keep you away from others to minimise the risk of infection," she said.
Symptoms of the airborne virus include fever, sore eyes and a cough followed by a red, blotchy rash three to four days later.
Parents of infants or others who are not fully vaccinated against measles are being urged to receive the free medication.
