The sexually transmitted diseases (STDs) or sexually transmitted infections (STIs) most people know and would think of as common is gonorrhea, chlamydia, or even HIV. But there is one sexually transmitted disease that is common, but people never talk about it like they should. It’s called Trichomoniasis.

In women, trichomoniasis can cause a foul-smelling vaginal discharge, genital itching, and painful urination. Pregnant women who have trichomoniasis might be at higher risk of delivering their babies prematurely.

This also means that public health programs aren’t putting as much effort into tracking or controlling its transmission as they might with other STIs.
As a matter of fact, Trichomoniasis (or “Trich”) is the most common curable STD. In the United States, CDC estimates that there were more than two million trichomoniasis infections in 2018.
