Trichomoniasis, “Trich”, is a very common STD caused by the protozoan parasite, Trichomonas vaginalis. Coinfection with other STDs and bacterial vaginosis is very common. Most people who have the parasite cannot tell they are infected.
Trichomoniasis is contracted by having oral, vaginal, or anal intercourse with someone who has the disease.
About 70% of infected people do not have any signs or symptoms. When trichomoniasis does cause symptoms, they can range from mild irritation to severe inflammation. Some people with symptoms get them within 5 to 28 days after being infected. Others do not develop symptoms until much later. Symptoms can come and go.
Without treatment, this infection can last for up to 3 months, or even years, so it is difficult to determine when or with whom the infection was acquired.
Trichomoniasis can be treated with either metronidazole or tinidazole. It is not recommended to drink alcohol within 24 hours after taking this medication. Re-infection occurs in about 1 in 5 people, usually within months after getting treated. Make sure that all sex partners get treated. Wait at least 7- 10 days after treatment and all symptoms resolved before resuming sexual activity.
