There has been a steady increase in notifications of Chlamydia trachomatis infection in Australia in the past decade. It is now the most commonly notified bacterial infection nationally (approximately 20,000 cases detected per year) and in 2001 Chlamydia notifications outnumbered hepatitis C notifications in the ACT.

General practitioners diagnose most cases. There has been a steady increase in notifications since 1996 when PCR technology was introduced. Some of this increase reflects the increased sensitivity of the molecular diagnostic technology and some is related to the ease of testing (eg. urine samples and self-inserted swabs), but it is likely that there is a true increase in the incidence of the disease in the community.
Since about 80% of infected women are asymptomatic, notifications mainly result from screening and contact tracing activities the extent to which these occur in the community is not known. Therefore, the true prevalence of the condition could be significantly higher than the notification data reveal.
