1. ‡'% in MSM' represents the proportion of the total male diagnoses attributed to men who have sex with men (MSM)

2. The increased workload in 2003 could be partly due to changes in the reporting system (the addition of S codes)

Chlamydia - uncomplicated genital chlamydial infection, KC60 code C4a, C4c
Gonorrhoea - uncomplicated gonorrhoea, KC60 code B1, B2
Syphilis - primary and secondary infectious syphilis, KC60 code A1, A2
Herpes -anogenital herpes simplex (first attack), KC60 code C10a
Warts - anogenital warts (first attack), KC60 code C11a

4. #Total diagnoses - all diagnoses made, includes all A, B, C and E KC60 codes
#Total workload - all workload not requiring a diagnoses, includes all D, P and S KC60 codes

5. *Data is confidential. Following recent ONS guidance on data disclosure, the HPA rules on publication of STI data with small cell sizes have changed. Cells with a value between 1 and 4 will now be anonymised with an astrix. In addition, where the anonymised cell can be deduced from the totals, the next smallest cells will also be anonymised.
