IPSWICH health officials have not diagnosed any more measles cases since a link between the Ipswich outbreak and several cases at a Queensland prison.
West Moreton Hospital and Health Service officials have diagnosed 12 local cases of the disease, sparking a public immunisation campaign.
Gene sequencing linked the outbreak of measles at the Woodford Correctional Services facility on the Sunshine Coast to the Ipswich cases.
A statement from Queensland Health confirmed 28 measles cases had been diagnosed within the prison.
The outbreak led to the immunisation of more than 1200 people at the correctional centre due to the highly infectious nature of measles.
Queensland's chief health officer Dr Jeannette Young urged parents to ensure their children had been vaccinated to protect them from infection.
"With a measles outbreak it is imperative as many people as possible are vaccinated," Ms Young said.
"That's why it concerns me that many young children in Queensland may not be protected from this serious disease and I am urging parents to make an appointment with their GP now.
"Immunisation is the most effective way to prevent measles and two doses of measles vaccine are needed to provide a high level of protection."
