From the Guidelines
Yes, trichomoniasis (trich) can be transmitted non-sexually, although sexual transmission is the most common route. Non-sexual transmission can occur through sharing moist objects like wet towels, bathing suits, or toilet seats, though this is relatively rare [ 1 ]. The parasite Trichomonas vaginalis can survive for several hours in a moist environment. Trichomoniasis can also be passed from mother to baby during childbirth, though this is uncommon.
Key Points to Consider
- The standard treatment for trichomoniasis is a single dose of metronidazole (2 grams) or tinidazole (2 grams), or metronidazole 500 mg twice daily for 7 days [ 1 ].
- All sexual partners should be treated simultaneously to prevent reinfection, and you should avoid sexual activity until treatment is complete and symptoms resolve.
- Even with non-sexual transmission, it's essential to complete the full course of antibiotics to effectively eliminate the infection.
- Metronidazole gel is not recommended for the treatment of trichomoniasis due to its low efficacy [ 1 ].
Important Considerations
- Pregnant women with trichomoniasis should be treated to relieve symptoms and prevent potential complications such as premature rupture of the membrane, preterm delivery, and low birth weight [ 1 ].
- Patients with trichomoniasis and HIV infection should receive the same therapy as those without HIV infection [ 1 ].
From the Research
Transmission of Trichomoniasis
- Trichomoniasis is primarily transmitted through sexual intercourse, as stated in the study 2.
- Transmission via fomites is rare, according to the same study 2.
- There is no evidence to suggest that trichomoniasis can be transmitted non-sexually, as the studies focus on sexual transmission 2, 3, 4.
Non-Sexual Transmission
- None of the provided studies suggest a non-sexual mode of transmission for trichomoniasis.
- The studies emphasize the importance of sexual transmission in the spread of the disease 2, 3, 4.
