<p>Data on sexually transmitted infections (STIs) are now sourced from the Genitourinary
Medicine Clinic Activity Dataset, Genitourinary Medicine (GUM) services return. Data
from GUM clinics on prisoners are unavailable prior to 2011.</p><p> </p><p>For the
most recent two years for which data is available, the following table shows all new
STI diagnoses among prisoners in England. Data from Genitourinary Medicine Clinic
Activity Dataset relate only to GUM services which are located in England.</p><p>

2012 data for chlamydia and “All new STIs” are not comparable to data from previous
years. Chlamydia diagnoses made among prisoners in GUM clinics that were reported
as “previously diagnosed at another service” have been excluded from 2012 data only.</p></td></tr><tr><td><p>4.
Data for “All New STIs” include: chancroid; lymphogranuloma venerum (LGV); donovanosis;
chlamydia; gonorrhoea; herpes: anogenital herpes (1st episode); HIV: new diagnosis;
molluscum contagiosum; non-specific genital infection; pelvic inflammatory disease
(PID) and epididymitis: non-specific; scabies; pediculus pubis; syphilis: primary,
secondary and early latent; trichomoniasis and warts: anogenital warts (1st episode).</p></td></tr><tr><td><p>5.
Data on prisoners are significantly underreported in 2011 due to the phased introduction
of Sexual Health and HIV Activity Property Types (SHHAPT) STI surveillance codes.</p></td></tr><tr><td><p>6.
Number of diagnoses between 1 and 4 with a population <10,000 are presented as
‘<5' to prevent deductive disclosure. Please see link for further details on data

</p><p>The following table also contains the number of chlamydia diagnoses among prisoners
aged 15-24 years in England for 2009-2011. Data are sourced from the National Chlamydia

Chlamydia data from community services are sourced from the National Chlamydia Screening

new laboratory reporting system (CTAD) that does not indicate diagnoses made among
prisoners.</p></td></tr><tr><td><p>2. Data follow calendar years (January to December),
