Trichomoniasis:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
Trichomonas vaginalis — a tetraflagellated, motile protozoan — causes trichomoniasis in females by infecting the vagina, the urethra and, possibly, the endocervix, bladder, Bartholin’s glands, or Skene’s glands; in males, it infects the lower urethra and, possibly, the prostate gland, seminal vesicles, or epididymis.
T. vaginalis grows best when the vaginal mucosa is more alkaline than normal (pH about 5.5 to 5.8). Therefore, factors that raise the vaginal pH — use of hormonal contraceptives, pregnancy, bacterial overgrowth, exudative cervical or vaginal lesions, or frequent douching, which disturbs lactobacilli that normally live in the vagina and maintain acidity — may predispose a woman to trichomoniasis.
Trichomoniasis is usually transmitted by intercourse; less commonly, by contaminated douche equipment or moist washcloths. In the United States, incidence is highest in women ages 16 to 35.

Vaginitis:
Vaginitis - epidemiology
(The 5-Minute Pediatric Consult)
- Candidiasis may present cyclically with menses, possibly owing to changing estrogen levels.
- Gonorrhea is more likely to be symptomatic at the time of menses owing to easier access to the upper reproductive tract.
- Body mass index (BMI) at the extremes is associated with increased risk of vulvovaginitis.
- The epidemiology of bacterial vaginosis is not well known because it is not a reportable disease, and 50% of cases may be asymptomatic.
Vaginitis - incidence
The exact incidence of vaginitis is unknown.

About prevalence and incidence statistics:
The term 'prevalence' of Trichomoniasis usually refers to the estimated population
of people who are managing Trichomoniasis at any given time.
The term 'incidence' of Trichomoniasis refers to the annual diagnosis rate,
or the number of new cases of Trichomoniasis diagnosed each year.
Hence, these two statistics types can differ:
a short-lived disease like flu can have high annual incidence but low prevalence,
but a life-long disease like diabetes has a low annual incidence but high prevalence.
