Trichomoniasis is a sexually transmitted disease or infection (also called an STD or STI). It can be treated and does not usually cause any serious damage. However, it can increase your risk of getting other sexually transmitted diseases or infections, particularly HIV. HIV is the virus that causes AIDS, which is a life-threatening disease. Also, if a pregnant woman has trichomoniasis, the disease can cause the baby to be born early or have a low birth weight.
The infection is caused by a parasite called Trichomonas vaginalis. It is usually passed from person to person during oral, vaginal, or anal sex. The infection can spread to others even when you don’t have symptoms.

The infection is treated with medicine that will kill the parasite. Don’t drink any alcohol while you are taking the medicine or for 2 days after you finish the medicine. Drinking alcohol while you are taking the medicine may cause severe nausea and vomiting.
For most people, the symptoms go away less than 1 week after treatment.
