OBJECTIVE: To compare the demographics of chlamydia in Leeds in 2003–2004 with 1994–1995.
METHODS: Laboratory data for all chlamydia diagnoses in Leeds in 2003-2004 were compared to 1994–1995.
RESULTS: For persons aged 15 to 54, total annualised positivity rates increased 4-fold from 159.0/106 in 1994/5 by ELISA (95% CI 150.4 to 167.9) to 644.8/106 in 2003/4 by SDA (95% CI 627.4 to 662.5). This increase was the same for both sexes; peak age groups remained 15–19 for women and 20–24 for men. Ethnicity data (Genitourinary Medicine (GUM) diagnoses only) showed a persistent relative risk of 10 for black as opposed to white ethnic groups. In 2003/4, GUM diagnosed 42% of chlamydia positives compared with 80% in 1994/95. 51% were diagnosed in the community: General Practice (39%), Contraceptive services (7%) and Chlamydia Screening Project (5%). A positive female was 4.5 times more likely than a positive male to be diagnosed in a non-GUM setting. Analyses of setting-specific positivity rates and geospatial distribution are underway.
CONCLUSIONS: Chlamydia continues to show a wide geospatial distribution with increased risk in under-25s and black ethnic groups. Women are now diagnosed mostly in community settings and efforts will need to be concentrated on partner notification to reduce transmission.
