Some people with symptoms of trich get them within 5 to 28 days after being infected, but others do not develop symptoms until much later. Symptoms can come and go, and without treatment, the infection can last for months or even years.
No one knows exactly how long someone can have vaginal trichomoniasis with few or no symptoms. We do know that women can have this infection for at least three months without symptoms of any kind, and we know that it can be transmitted to a sex partner even when it is causing no symptoms.
The accuracy of trichomonas tests depends on the type of test used and who it’s used on. Tests done on people with male genitals are usually less accurate. As no test is 100% accurate, there’s a small chance you’ll get a negative result when you do have trichomonas. This is called a false negative result.
Your symptoms should go away after a week. If your symptoms continue longer, talk to your doctor about getting retested and retreated. See your doctor for a follow-up test for trich at least 3 months after your treatment.
The bottom line. People can have trichomoniasis for months without showing any symptoms. If you or your partner suddenly have symptoms or test positive for it, it doesn’t necessarily mean that someone’s cheating. Either partner may have gotten it in a previous relationship and unknowingly passed it on.
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.
The parasite cannot survive in the mouth or rectum. The disease can affect both men and women, but the symptoms differ. The infection usually does not cause symptoms in men and goes away on its own in a few weeks.
Complications of untreated trichomoniasis in men include prostatitis, epididymitis, urethral stricture disease, and infertility, potentially resulting from decreased sperm motility and viability.
Trichomoniasis can be diagnosed by looking at a sample of vaginal fluid for women or urine for men under a microscope. If the parasite can be seen under the microscope, no further tests are needed. If this test isn’t conclusive, tests called rapid antigen tests and nucleic acid amplification may be used.
Trichomoniasis is usually treated quickly and easily with antibiotics. Most people are prescribed an antibiotic called metronidazole which is very effective if taken correctly. You’ll usually have to take metronidazole twice a day, for 5 to 7 days.
Trichomoniasis parasites are very sensitive to drying, but can survive for several hours in various body fluids or on moist objects such as sponges or towels. Fifty percent of women and 90% of men have no symptoms. The incubation period is from 3 to 28 days, but can be longer.
Currently, the CDC and WHO recommend a single 2-g dose of oral metronidazole or tinidazole as first-line treatment and a 7-day regimen of two daily 400-mg or 500-mg doses of oral metronidazole as second-line treatment for Trichomonas vaginalis infection, but evidence has shown that one dose might not be enough,
Trichomoniasis is the most common curable sexually transmitted infection and easily treatable with a course of antibiotics. It’s known for its pungent fishy odor. “The trichomoniasis infection can be quite smelly,” says Minkin. “It’s a more pronounced fishy odor than bacterial vaginosis.”
Trichomoniasis can be cured with a single dose of prescription antibiotic medication (either metronidazole or tinidazole ), pills which can be taken by mouth. It is okay for pregnant women to take this medication.
