{"doi":"10.1093/cid/ciac618","title":"Pharyngeal<i>Chlamydia trachomatis</i>in Men Who Have Sex With Men in a Human Immunodeficiency Virus (HIV) Pre-exposure Prophylaxis Program in Hanoi, Vietnam","abstract":"to the editor—We read with great interest the report by Evers et al [1], exploring the anatomical site distribution and risk factors for pharyngeal Chlamydia trachomatis infections in a large sample of men who have sex with men (MSM) in The Netherlands. The investigators reported a 10.6% prevalence of C. trachomatis overall, but a low prevalence of pharyngeal infections (1.2%). Compared with rectal and urogenital sites, pharyngeal C. trachomatis infections comprised the lowest prevalence by anatomic site. We would like to share findings of an ongoing study screening for C. trachomatis and Neisseria gonorrhoeae among MSM enrolled in a human immunodeficiency virus (HIV) pre-exposure prophylaxis (PrEP) program in Hanoi, Vietnam. PrEP has been available in Vietnam since 2019 [2]. The Sexual Health Promotion Clinic is the largest PrEP program in Hanoi, providing PrEP for 2695 individuals cumulatively [3]. Our study provides quarterly screening for C. trachomatis and N. gonorrhoeae at 3 anatomic sites using nucleic acid amplification testing, as recommended by the Vietnam national PrEP guidelines [4].","journal":"Clinical Infectious Diseases","year":2022,"id":310243,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":0,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9611,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2022-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":308066,"name":"Paul C.
