MQ-Trichomonas vaginalis ...

Trichomonas vaginalis is a common protozoal infection, causing symptomatic vaginitis in women and often remaining asymptomatic in men. Trichomoniasis increases HIV transmission risk and poses risks during pregnancy. Underdiagnosis and patient self-treatment are common, while clinicians often overlook testing of sexual partners. The infection is primarily sexually transmitted, with risk factors including a history of STIs, new/multiple partners, contact with infected individuals, IV drug abuse, and lack of barrier contraception. Prevalence varies by gender, with higher rates in women aged 40-49 compared to chlamydia infections, which peak in 19-24-year-olds.
