  • *Unconfirmed positive is a sample with a positive or equivocal dual NAAT result that was negative on two supplementary tests.

  • †Confirmed positive is a sample with a positive or equivocal dual NAAT result that was positive on at least one of three supplementary tests.

  • ‡Denominator is Natsal-3 participants aged 16–44 years who reported at least one partner, ever.

  • §For chlamydia, men and women were combined because the denominators were too small for data to be reported by gender separately.

  • HR-HPV, high risk human papilloma virus; NAAT, nucleic acid amplification test.
