Key findings
- In the last decade, the number of chlamydia notifications in 15-29 year olds in NSW increased by 336.3%, from 3,222 notifications in 2001 to 14,057 in 2010.
- Medicare data showed a parallel trend in chlamydia testing in young people aged 15 – 34 years, increasing from 35,384 tests rebated in 2000 to 154,218 in 2010, a 336% increase.
- One community-based study in NSW estimated chlamydia prevalence in young males and females to be 3.1% (95%CI:1.0 – 8.0%) and six studies based on clinic populations found the prevalence ranged from 3 to 12%.
- Analyses of data from a national sentinel surveillance system in sexual health services showed an increase of 28% in chlamydia positivity in young women aged 15-29 between 2004 and 2010 in NSW.
- We did not identify ongoing estimates of chlamydia incidence, chlamydia-related sequelae or testing rates in Aboriginal and Torres Strait Islander people attending Aboriginal health services in NSW.
