Objectives: This study assessed the prevalence and correlates of asymptomatic genital tract infection with Neisseria gonorrhoeae and Chlamydia trachomatis among emergency department patients.
Methods: Individuals seeking emergency department evaluation for nongenitourinary complaints provided urine samples for N gonorrhoeae and C trachomatis testing by ligase chain reaction and completed a sociodemographic and behavioral questionnaire.
Results: Asymptomatic N gonorrhoeae or C trachomatis was found in 9.7% of persons tested. Correlates of C trachomatis infection included younger age, residence in high-morbidity zip code areas, previous history of N gonorrhoeae or C trachomatis, and number of sex partners in the past year.
Conclusions: Urine-based screening of asymptomatic emergency department patients detected significant numbers of N gonorrhoeae and C trachomatis infections. Targeted screening programs may contribute to community-level prevention and control of sexually transmitted infections.
