Key messages

  • The annual incidence of chlamydia in sexually active female students was 3.4 per 100 person-years, but 6.6 per 100 person-years in teenagers.

  • Incident chlamydia infection was independently associated with a new sexual partner, smoking, bacterial vaginosis, high risk human papillomavirus and age <20 years.

  • One in four women with chlamydia at baseline tested positive again after a median of 16 months.

  • Recommendations from chlamydia screening programmes to routinely retest those who have been recently treated for chlamydia should be publicised.
