WHITSUNDAY residents are warned to be on the alert for measles symptoms following a confirmed case in the area.
An overseas tourist was infectious when they visited Airlie Beach on August 18.
A Queensland Health spokeswoman said anyone who was not immune through past disease or vaccination may be vulnerable.
Measles is one of the most infectious of all communicable diseases and is spread by coughing and sneezing.
The initial symptoms of fever, lethargy, runny nose, moist cough and sore and red eyes usually start about 10 days after infection.
These are followed a few days later by a blotchy red rash on the face, which then becomes widespread.
Queensland Health says anyone who develops the symptoms should phone their GP before visiting, so they can avoid the disease spreading to other patients.
