 Chlamydia notifications and hospitalisations

Current position

Women’s rate of Chlamydia notifications has continued to rise more quickly than that of men. In 2011, there were 318 Chlamydia notifications per 100,000 women compared to 248 per 100,000 for men.

The hospitalisation rate also shows women having much higher rates than men (there is no new data this year).

Gender gaps

  • The Chlamydia notification rate for women was 1.3 times higher than for men in 2011.
  • The Chlamydia hospitalisation rate for women was 7 times higher for women than men in 2009-10.
The direction of change over time
Chlamydia cases have been growing among women and men, but more rapidly among women, who also experience the most hospitalisations.
Discussion

Chlamydia is the most common sexually transmissible infection in Australia today. It particularly affects young women and is a major cause of infertility as a result of not being treated early.

Chlamydia is a communicable disease that must by law be notified to government. The higher notification and hospitalisation rates in young women reflects the fact that women’s symptoms are less definitive and therefore less easily diagnosed and treated than those of young men.

Year collected: 2011 for notifications and 2009-10 for hospitalisations, and preceding years.
