Our objective is to determine the prevalence of six common STIs, Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), Mycoplasma genitalium (MG), genital herpes (herpes simplex virus type 2 [HSV-2]), HIV, and syphilis for patients visiting a sexual health clinic in Guangzhou, China. Demographics, sexual health, and medical histories were collected at patient intake. Patients diagnosed with anogenital warts (N\u2009=\u2009200) were invited to participate. We collected urine samples, and urethral, cervical, and rectal swabs to test for CT, NG, and MG, and blood samples for serological detection of HSV-2, syphilis, and HIV. Overall 49 (24.5%) had a co-infection (22.2% of men and 27.7% of women). All six STIs were observed among men: CT (6.8%), NG (3.4%), MG (5.1%), HIV (4.3%), HSV-2 (4.3%), and syphilis (1.7%). Women had fewer STIs, but at higher rates: CT (13.3%), MG (6.0%), and HSV-2 (8.4%). Individual men had up to two co-infections, while women had no more than one co-infection. Chlamydia was the most common STI. Patients aged 18\u201325\u2009years (35.4%) had the highest prevalence. Although opportunistic screening is often applied for high-risk groups, expansion to patients with anogenital warts in all health-care settings would improve detection of problematic asymptomatic co-infections, thereby increasing China\u2019s capacity to contribute toward global surveillance systems.<\/jats:p>","DOI":"10.1177\/0956462419890496","type":"journal-article","created":{"date-parts":[[2020,8,26]],"date-time":"2020-08-26T02:25:42Z","timestamp":1598408742000},"page":"1073-1081","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":7,"title":["Prevalence
