Queensland Health has issued a new measles alert for Brisbane's northside after a child returned from overseas with the virus.

The child was unknowingly infectious when visiting Just Pharmacy at Murrumba Downs Shopping Centre between 7pm and 7.45pm on Tuesday July 2 and Taigum Square Shopping Centre on Beams Road, Taigum, between 10.15am and 11.15am on Friday July 5. Metro North Public Health physician Doctor Rosie Muller said people who were in these areas at the same time should seek medical advice if they develop measles symptoms.

Measles is a highly infectious virus spread by tiny droplets generated when sufferers cough and sneeze. Its symptoms include a fever; a runny nose; fatigue; and sore, red eyes, followed a few days later by a red rash that typically starts on the face before spreading to other areas on the body. The virus can eventually result in serious complications such as inflammation of the brain and pneumonia.

This latest alert brings the number of cases recorded in the Metro North area in 2019 to four. Queensland has recorded 16 measles cases so far this year – two more than for the whole of 2018, the Courier-Mail reports.

A measles vaccine is free for anyone who requires it. Further advice is available by calling 13HEALTH (13 43 25 84).
