Queensland Syphilis Surveillance Service

The Queensland Syphilis Surveillance Service (QSSS) is a secure, confidential, single state-wide database established to improve the accuracy of syphilis reporting, monitor trends in syphilis notifications and improve the management of individuals affected by syphilis. All laboratory-based positive syphilis test results for Queensland residents are reported to the QSSS.

The QSSS records the history of an individual's pathology results for all tests related to the diagnosis and monitoring of syphilis and any associated treatment. It aims to provide the treating clinician with information about a client's history of syphilis infection to assist in the diagnosis, management, education and treatment. The QSSS also requests information from diagnosing clinicians to confirm treatment, keep the records complete and inform service providers about risk factors for contracting syphilis.
