Tigerair is contacting hundreds of passengers from 13 different flights after two people who travelled on the same plane tested positive to coronavirus.

The airline pulled the plane from service on Thursday after Queensland Health alerted it to a positive case of coronavirus on board.

Two people with the virus are in isolation in the Gold Coast University Hospital.

The pair flew from Melbourne to Coolangatta on Tigerair flight TT566 on January 27.

Tigerair said the plane was taken out of service as a "precautionary measure" for extra cleaning.

It had flown around Australia since Monday to destinations including Cairns, Brisbane, the Gold Coast, Melbourne, Adelaide and Perth.

I've flown on the plane, should I be worried?

The tail number of the plane is VH-VUD, a 737-800.

The man and a companion were seated in 11A and 11B.

The plane flew back to Melbourne from the Gold Coast within an hour but Tigerair's Group Medical Officer Dr Sara Souter said the risk of anyone contracting the virus is "low for passengers travelling on the aircraft in subsequent days".

A student from Crestmead State School, south of Brisbane, had been put into isolation, the schools said, after concerns about possible exposure.

Queensland Chief Medical Officer Jeannette Young said people shouldn't be alarmed if they had been on the plane.

"The danger is going to be absolutely minimal," Dr Young said.

"I can't say it's zero because we don't have that full information.

"When you cough or sneeze — and this man was symptomatic on the plane — you can cough or sneeze the virus particles ... and they land on surfaces.

"Usually they dry out very quickly and are no problem.

"Coronaviruses don't usually survive on surfaces for long but we don't know with this virus that's why I say be cautious and wash your hands regularly.

"But if they develop respiratory symptoms in the next 14 days mention to your healthcare provider you were on one of those planes."

Anyone who was on flight TT566 should call 13HEALTH.

What extra steps are domestic airlines taking?

So far, there's been no change.

Airlines are talking with federal health agencies and taking advice about what steps should be taken.

Qantas said it was "operating as normal" but monitoring the situation.

Virgin Australia and Tigerair said it was business as usual.

But staff are being briefed and planes have masks on board should anyone show symptoms.
