Trichomoniasis

Premature birth and low birth weight can result from trichomoniasis during pregnancy.

According to estimates from the World Health Organization (WHO), 142 million new cases of trichomoniasis among adults and children aged 15 to 49 occurred globally in 2012. Around 13.8 million new cases of trichomoniasis for females and 13.6 million for males were reported in the American region in 2012, adding to the approximately 18.8 million existing cases for females and 3.2 million existing cases for males. Trichomoniasis appears to peak in between 40 and 50 years of age, in contrast to most STIs, where the number of cases is highest in women between the ages of 15 and 25.

Trichomoniasis can make it more likely for someone to contract or spread other STDs. For instance, trichomoniasis can lead to vaginal irritation that makes it simpler to contract HIV or transmit it to a sexual partner.
