‡Code suffixes to identify oral or rectal chlamydia infections were introduced to GUMCAD in 2011. However, as the use of these suffixes was not consistent across all clinics in 2011 the data presented here includes all chlamydia infections. In future, it will be possible to provide information on the site of infection.
§New HIV diagnoses in 2011.
GUM, genitourinary medicine; STI, sexually transmitted infection.
