Health authorities are urging Queenslanders to get vaccinated after the latest measles victim spent four hours in the Brisbane nightclub district.

Details of the fifth case were released by Metro South Health on Sunday following confirmation last week that four cases had been reported.

The latest patient’s movements included visiting the Fortitude Valley nightclub district for four hours from 11pm on Saturday March 31, during the Easter long weekend.

Public Health physician Bhakti Vasant said it was vital for residents, if they weren’t already, to be vaccinated for measles.

“Vaccinations are recommended for anyone born after 1965, who has not had two documented doses of measles, mumps, rubella (MMR) vaccine or had proven measles,” Dr Vasant said.

“Anyone who may have come into contact with an infectious person, and are uncertain of their immunity to measles should speak to their GP immediately.”

Last month, a patient visited Roma Street Station while unknowingly infected and travelled on the train line in Brisbane’s northside.

Parts of south-east Queensland have immunisation rates below the national herd immunity target of 95 per cent of all children.

Brisbane North is not far off the target, with 94.3 per cent of all five-year-old children being fully immunised.

The rate is 93.4 per cent in Brisbane South, and 92.2 per cent on the Gold Coast, according to federal government data from 2016-17.

Local drop-in clinics are offering free vaccinations until next Saturday in Jimboomba, Marsden, Crestmead, Browns Plains and Logan.

Measles is one of the most infectious of all communicable diseases and is spread by tiny droplets through coughing and sneezing.

It causes fever, lethargy, moist cough, runny nose and then a red spotty rash and sore eyes a few days later. The rash often starts on the face and then becomes widespread.

Measles may lead to pneumonia, brain inflammation and other serious illness.

While extensive contact tracing was being conducted, Dr Vasant said residents in the Brisbane and Logan areas also needed to be alert for symptoms.

Symptoms usually start around 10 days after contact, but can occur between seven and 18 days after contact with an infectious person, she said.

Contact your GP or phone 13HEALTH for vaccination information.
