In one sentence, describe what the following article is about:

Often called trich, trichomoniasis is a type of vaginitis that is caused by a protozoa or parasite. It affects up to five million people in the US each year. This organism is a small parasite with a tail. In men, if trich is untreated, it can lead to chronic prostatitis. The symptoms of trichomoniasis include an itchy, green, and possibly frothy discharge with a fishy odor. This disease is sexually transmitted, so if you think you have it, you should let your sexual partner know so both partners can be tested and treated before resuming intercourse. If one of you is diagnosed then both of you need treatment. Traditionally, the diagnosis for trich is done in a doctor’s office. A wet prep is done by placing vaginal secretions under the microscope with a drop of saline solution. This will cause the parasite under the microscope to swim across the field and be identified.  There can be doctor discrepancy. Because of this, your doctor may also perform more standardized testing, such as a PCR assay to determine exactly what disease you have. You may also be given a pap smear as well. If this is not treated in pregnant women, there can be complications when giving birth such as low birth weight and prematurity due to a premature rupture of membranes (PROM). As with BV, trich can be treated with oral medication such as Flagyl. The usual dose is 2 grams taken once orally. You should avoid alcohol while taking Flagyl. Your partner should also take Flagyl at the same time. While you are taking the medication, intercourse should be avoided until both partners have completed treatment. Some studies recommend the use of Tindamax for trich as well. If prescribed, you will only have to take one 2 mg dose. This medication has a cure rate between 86-100%.
