Epidemiology And Transmission

Although trichomoniasis (T. vaginalis) is the most common nonviral sexually transmitted disease, epidemi-ological data are limited because official reporting is not required. According to the World Health Organization 174 million new infections occurred in 1999[11] with 8 million occurring in North America. Prevalence varies in different populations; the prevalence of trichomoniasis among black American population is higher than any other population in the United States.[12]

Transmission of Trichomonas parasites is direct, person-to-person. T. vaginalis is almost exclusively transmitted directly by sexual intercourse. However, infection in newborns and infants is commonly a consequence of mother-to-child transmission during delivery.[13] Newborn girls can acquire infection from their infected mothers during passage through the birth canal and remain asymptomatic until puberty. Transmission of T. vaginalis in children before and after puberty may be indirect especially in an environment with infected family members.[13]

T. tenax is spread by direct as well as indirect mouth-to-mouth contact, sharing of oral hygiene utensils such as a toothbrush may be an important source of transmission.1-1-1 A zoonotic transmission may also be possible, as a PCR-based molecular analysis of isolates obtained from dogs and cats confirmed the presence of T. tenax in these animals.[14]
