A man who flew into Australia from overseas has triggered a health alert in Queensland after he visited shops, a service station and a bakery while infected with measles.
The Department of Health raised the alarm about the case on Saturday, declaring multiple premises exposure sites after the traveller visited them between July 3 and Friday, July 14.
The man was unknowingly infectious when he arrived at Brisbane Airport on July 3 and visited several businesses and locations on Brisbane's northside and Redcliffe Peninsula.
The man had flown to Australia from Jakarta on July 2 before travelling from Melbourne to Brisbane on Flight QF610 at 9.50am the following day.
Those who attended the sites the man visited in Queensland were urged to be on the lookout for symptoms, wear a mask and call a GP or medical centre ahead to ensure they could be isolated from other people.
The man was at Brisbane Domestic Airport and the Nudgee Service Centre on July 3 and visited the service centre again on July 8.
He also visited CJ's Pastries at Kippa-Ring on July 3, , Kippa-Ring Shopping Centre on July 4 and Vital Life Centres at Scarborough on July 4-5, July 8 and July 10.
Also on July 8, the man visited City Cave Redcliffe Sauna at Margate and Dan Murphy's at Woolloongabba and was at DFO Skygate at Brisbane Airport on July 9.
The man presented at Redcliffe Hospital Emergency Department on July 13 and 14.
Metro North Public Health physician Megan Young said anyone at these locations during these times should monitor themselves for symptoms for 18 days from when they might have had contact.
"If they do develop symptoms, they should seek medical advice," she said.
Early symptoms of measles include a fever, tiredness, cough, runny nose, and red, inflamed eyes.
"Those symptoms then progress to a blotchy red rash, which often starts on the face before becoming widespread," Dr Young said.
Queensland Health recommends anyone born in 1966 or after who has not had two documented doses of measles, mumps, rubella (MMR) vaccine or had proven measles, should visit their doctor to get vaccinated for measles.
