  • + Notes

    Data include all notifications in NSW regardless of place of residence. Cases with sex 'not stated' are included in the total. Cases are reported by quarters. 2008Q1 means the first calendar quarter of 2008. Crude rates are shown.

  • + Commentary

    Chlamydia is a sexually transmissible infection caused by the bacterium Chlamydia trachomatis. Many people who are infected do not have symptoms of infection but can still transmit the bacterium. Chlamydia can lead to infertility, and other complications if not treated. This report includes cases of congenital chlamydia; there are usually fewer than 50 cases per year.

    Given the largely asymptomatic nature of chlamydia infections, the notification data are heavily influenced by health screening behaviour and testing practices. NSW Health’s Denominator Data Project, commenced in January 2012 and has shown that at least part of the increase in notifications to 2012 was due to increased testing. The higher rate of infection in women is most likely due to a testing bias.

    The Chlamydia Fact Sheet provides more information about this disease.
