A study was conducted in the confined population of a state school for girls where the majority of students gave a history of past sexual intercourse. As part of a six-year survey for gonorrheal infection, examinations were also conducted for Trichomonas vaginalis and yeast infections. From a total of 6,304 specimens examined, the presence of T vaginalis in 20.3% was revealed. Screening for yeast and Neisseria gonorrhoeae revealed the presence of yeast in 10.4% and N gonorrhoeae in 6.3%. Multiple agents were frequently present (4.3%).
The prevalence of T vaginalis infection was determined to be 35.2% in a series of 338 consecutive admissions to the institution. Screening for T vaginalis, yeast, and N gonorrhoeae in the presence of vaginal discharge is recommended.
