Hundreds At Risk After Another Case Of Measles Detected On Qantas Flight

A fresh alert has been issued by NSW Health after two children were diagnosed with the measles after returning to Sydney from Sri Lanka.

The unvaccinated children returned on Qantas flight SQ221 on Friday, January 11, and were diagnosed on Tuesday.

The two new cases bring the total number of overseas-acquired measles since Christmas to six.

NSW Health has issued a warning for those at Sydney Airport, as well as anyone who travelled on trains from the airport to Meadowbank on the morning of the Friday.

While infectious, the children also went to Ryde Hospital Emergency Department on Sunday, and the Carlingford Epping Surgery General Practice and Douglass Hanly Moir Pathology on Monday.

"The children are now isolated and recovering at home," NSW Health said in a statement.

Patients at the medical centres who were present at the same time as the children are being contacted by a local public health unit to be assessed for the disease.

“If you develop symptoms please call ahead to your GP so that you do not wait in the waiting room with other patients,” Dr Vicky Sheppeard, Director Communicable Diseases Branch said.

“The measles-mumps-rubella (MMR) vaccine is safe and highly effective protection against measles and is available for free for those aged 1 to 52 from your GP. If you are unsure whether you have had two doses, it is quite safe to have another dose.”
