Background/introduction: Previous research shows that female sex workers (FSW) are at higher risk of certain sexually transmitted infections (STIs), and that migrant FSW appear to be at even higher risk. 
Aim(s)/objectives: To evaluate the characteristics of FSW presenting to our inner London clinics who tested positive for either Chlamydia (CT) or gonorrhoea (GC), including information about sexual partners outside of work.
Methods: Retrospective case note review of patients identified by the Sexual Health and HIV Activity Property Type (SHHAPT) code ‘SW’ who also had either chlamydia or gonorrhoea in 2012-2014. 
Results: To date: Age range 18-56; 76% (87/114) were ≤30 yrs. 103/114 (90%) were born outside of the UK; 77/103 (75%) were from Eastern Europe. 129 episodes of infection were seen in 114 women. 83/129 (64%) were vaginal infections (CT, GC or both); 40/120 (31%) pharyngeal and 26/129 (20%) rectal. 21/114 (18%) reported unprotected vaginal sex (UPVI) with clients. Where recorded 71/93 (76%) had a partner outside of work; of these 77% reported UPVI. 86/114 (75%) were HIV negative; 16% had never tested. 58/114 (51%) were deemed to have at least one vulnerability. 

	2012	2013	2014
Total number FSW seen 	560	538	517
*Number of CT infections	16	28	47
*Number of GC infections	8	18	22
Prevalence  CT (%)	2.8	5.2	9.1
Prevalence GC (%)	1.4	3.3	4.2
*10 patients had both CT and GC

Discussion/conclusion: Prevalence of both CT and GC is increasing in this cohort of vulnerable women, highlighting the importance of dedicated FSW clinics such as ours.
