What this research studies

From your perspective, the team will compare the usual metronidazole schedules with a single-dose secnidazole option to see which clears the infection more often. If you join, you would take the assigned oral medication and come back for follow-up visits and tests to confirm whether the infection is gone. The research includes both women and men because past studies focused mostly on women and left treatment questions for men unanswered. The researchers will also record side effects and any repeat infections to find safer, easier treatment options.

Who could benefit from this research

Good fit: Adults diagnosed with Trichomonas vaginalis who can safely take oral nitroimidazole medications would be the ideal candidates.

Not a fit: People without a trichomonas infection, those allergic to nitroimidazoles, or those for whom oral antibiotics are unsafe may not receive benefit from participation.

Why it matters

Potential benefit: If successful, this work could produce a simpler, better-tolerated single-dose option that cures more infections and reduces onward transmission.

How similar studies have performed: Previous trials showed multi-dose metronidazole beats single-dose metronidazole in women, and a recent trial found single-dose secnidazole was better than placebo in women, but there is little data for men.
