Trichomoniasis vs. Chlamydia
Both trichomoniasis and chlamydia are sexually transmitted diseases.

Trichomoniasis is not chlamydia. Trichomoniasis is caused by the protozoan parasite, trichomonas vaginalis, whereas chlamydia is a bacterial infection caused by Chlamydia trachomatis. The trichomonas infection affects genital organs, but chlamydia affects both respiratory and genital tracts.

What is trichomoniasis?

Trichomoniasis is a common and curable sexually transmitted disease. The infection most commonly affects the lower genital tract (cervix, vulva, vagina, or urethra) of women. In men, the infection affects the urethra. The infection spreads through the semen or vaginal fluids but does not spread by hugging, kissing, sharing food, and sitting on the toilet seat.

Most people with trichomoniasis do not show any symptoms that make the infection spread quickly.

Trichomoniasis transmission

Trichomoniasis spreads via the semen and vaginal fluids during:

  • Sexual intercourse
  • Anal sex
  • Oral sex

What are the symptoms of trichomoniasis?

Seventy percent of the people with trichomoniasis do not show any symptoms. The people usually exhibit symptoms one week after exposure to the infection.

The following are the few symptoms of trichomoniasis:

  • Thin white, green, or yellow vaginal discharge with a foul odor
  • Pain and swelling in the vaginal region
  • Whitish discharge from the penis
  • Crotch discomfort
  • Painful and burning sensation during urination
  • Pain during intercourse
  • Pain during ejaculation

What are the risk factors for trichomoniasis?

The factors that increase the risk of trichomoniasis include:

  • Multiple sex partners
  • Neisseria gonorrhoeae infection
  • Previous history of sexually transmitted infections
  • A previous trichomoniasis episode
  • Unprotected sex

How to diagnose trichomoniasis

Your doctor may order tests to examine a sample of vaginal fluid (women) or a urethral swab (men) under a microscope. If parasites are present, no further tests are required.

The diagnosis includes:

  • Physical examination (includes an examination of the pelvis)
  • Urine culture
  • Genital swab test
  • If swab tests do not show parasites, then:
    • Rapid antigen test
    • Nucleic acid amplification test

How is trichomoniasis treated?

The following treatment options for trichomoniasis include:

  • Your provider might recommend several lower doses of metronidazole or tinidazole for about five to seven days.
  • Refrain from sex until you and your partner(s) complete treatment.
  • Even after receiving treatment, get tested again in three months.
