Key Takeaways
- Trichomoniasis prevalence is highest among women aged 35-49 in US at 3.2%
- African American ethnicity increases risk 5.6-fold compared to whites per NHANES
- Low socioeconomic status correlates with 2-3 times higher prevalence
- NAAT sensitivity 95-99% for vaginal swabs in women
- Wet mount microscopy sensitivity only 51-65% in symptomatic women
- Culture sensitivity 75-85% but 3-7 day turnaround
- Globally, Trichomoniasis affects approximately 156 million new cases annually according to WHO estimates
- In the United States, about 3.7 million people have trichomoniasis, with no more than 30% developing symptoms
- Prevalence among women in the US is estimated at 2.1% based on NHANES data from 2013-2016
- Vaginal symptoms like discharge reported in 10-30% of infected women
- Frothy yellow-green vaginal discharge classic in 20-50% symptomatic cases
- Vulvovaginal itching or irritation in 40-60% of women
- Metronidazole 2g single dose cures 84-98% infections
- Tinidazole 2g single dose efficacy 92-100%
- Metronidazole 500mg BID x7 days 86-92% cure rate
Trichomoniasis affects millions yearly, but key US risk factors and effective NAAT screening drive prevention.

How We Rate Confidence
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
