Persistent, undetected Trichomonas vaginalis infections?

Abstract

In a recent large, randomized, controlled trial , 64 participants received a diagnosis of infection with Neisseria gonorrhoeae, Chlamydia trachomatis, or Trichomonas vaginalis during intervals in which they reported not having sex. We considered the problems that might lead to this paradoxical situation, including errors in laboratory testing and patient reporting and treatment failure. Our findings regarding N. gonorrhoeae and C. trachomatis infection were consistent with these scenarios; however, the findings regarding infection with T. vaginalis were surprising.
