Epidemiologic analysis of Trichomonas vaginalis infection in inflammatory smears

Infections of the lower reproductive tract are common in Indian women of reproductive age. Hospital-based cytologic screening was undertaken on 63,265 women. The smears were examined for the presence of specific infections, such as Candida, herpes simplex virus, human papillomavirus, Trichomonas vaginalis (TV) and Chlamydia. This paper highlights the prevalence of TV infection in inflammatory cervical smears. Among the various infections detected, the rate of TV infection was the highest (5.1%). On further analysis the rate of TV infection showed an increasing trend up to the age of 49 years; an inverse association was observed with the educational status of the women. The prevalence was high in women with clinical signs (vaginitis, 6.9%) and low in those with a prolapsed uterus (1.2%) as compared to a normal cervix. These observations reveal the need for providing proper counseling and education on sexual behavior and genital hygiene besides treatment to control and prevent these infections.
