From the Research
Yes, Trichomonas vaginalis can be transmitted through oral sex, although this route of transmission is less common than vaginal intercourse. Trichomonas vaginalis is a protozoan parasite that primarily infects the urogenital tract, causing trichomoniasis. During oral-genital contact, the parasite can be transferred from infected genitals to the mouth or throat of a partner. The parasite thrives in warm, moist environments and can survive briefly outside the body, making transmission possible during intimate contact. However, oral trichomoniasis is relatively rare compared to genital infections.
Key Points to Consider
- If infection occurs, treatment typically involves a single 2-gram dose of metronidazole or tinidazole taken by mouth, which is effective for both oral and genital infections 1.
- It's essential that all sexual partners be treated simultaneously to prevent reinfection, and patients should abstain from sexual activity until treatment is complete and symptoms resolve, typically about a week.
- Using barrier methods like dental dams during oral sex can help prevent transmission of this and other sexually transmitted infections.
- The most recent and highest quality study on the treatment of Trichomonas vaginalis infection suggests that metronidazole and tinidazole are effective treatments, but resistance to these drugs is a growing concern 1.
Treatment and Prevention
- Treatment of Trichomonas vaginalis infection typically involves a single 2-gram dose of metronidazole or tinidazole taken by mouth.
- It's crucial to treat all sexual partners simultaneously to prevent reinfection.
- Patients should abstain from sexual activity until treatment is complete and symptoms resolve, typically about a week.
- Using barrier methods like dental dams during oral sex can help prevent transmission of this and other sexually transmitted infections.
Resistance and Future Directions
- Resistance to metronidazole and tinidazole is a growing concern, and novel treatment options are needed 1.
- Further research is necessary to develop new treatments and prevent the spread of Trichomonas vaginalis infection.
