About measles
Measles is a highly infectious viral illness and is spread from person to person through the air by breathing, sneezing or coughing. Just being in the same room as someone with measles can lead to infection if you are not immune. Measles can be serious, with around one in 10 people who get it needing to be hospitalised.
"The first early symptoms of measles are fever, runny nose, sore red eyes and cough," Miller said.
"After three to five days a red, blotchy rash appears on the face and head and then spreads down the body."
Anyone who thought they had measles should stay home and call their doctor or Healthline to arrange an assessment, to avoid putting anyone else at risk.
• Anyone who thinks they have been exposed to measles or is exhibiting symptoms, should not go to the ED or after-hours clinic or general practitioner. Instead, call your GP any time, 24/7 for free health advice.
