A one-year-old child has contracted measles while overseas, which has prompted both South Australian and Victorian health authorities to issue a community alert.
The child travelled from Dubai to Adelaide via Melbourne before presenting at Adelaide's Women's and Children's Hospital Emergency Department on Thursday night.
SA and Victorian health authorities are urging anyone who isn't fully immunised against measles to be alert for symptoms, especially those who were in the same location as the child.

"Symptoms of measles start with fever, cough, runny nose, and sore eyes, followed by a blotchy rash which usually begins on the head and then spreads down the body," SA Health said in a statement.
"If you believe you have measles symptoms, contact your doctor before you visit so precautions can be taken to avoid spreading the infection to others."
