Trichomonas can infect both women and men. Trichomonas infection in women mainly causes trichomoniasis, while infection in men is usually asymptomatic and we refer to it collectively as trichomoniasis. Trichomoniasis itself is not difficult to treat and is mainly treated with oral nitroimidazole drugs. 1.First time infection: Patients with first time infection should take oral metronidazole or tinidazole under doctor’s instruction, the dosage and the course of treatment should be carried out according to the doctor’s prescription, and the treatment should be adhered to, 90%-95% of the patients can be cured. 2. Relapse or reinfection: Since trichomoniasis has a higher chance of relapse or reinfection, patients need to be reviewed regularly during the first 3 months of treatment. However, because trichomoniasis is a sexually transmitted disease, trichomonas can also infect multiple sites at the same time and has a higher chance of reinfection and recurrence. Trichomonas parasites are found in the glands of the perineum or vaginal folds in women, and in the folds of the foreskin, urethra or prostate in men. In addition to direct infection through sexual contact, patients can also be infected indirectly through public baths, bath tubs, bath towels, swimming pools, bidets, contaminated clothing, and contaminated instruments or dressings. If a patient with trichomoniasis continues to have unhygienic or unprotected sex during treatment or after cure, continues to go to the above-mentioned public places without paying attention to protection, or if underwear and towels that have been in close contact during the illness are not disinfected at high temperature, it is easy to be infected with trichomoniasis again or to have a relapse of the disease. Therefore, trichomoniasis is not a difficult disease to treat, as long as the patient identifies the cause of the infection and avoids the above-mentioned triggering factors in daily life, recurrence or reinfection can be prevented. Treatment of the patient and the partner at the same time can help reduce the chance of recurrence or reinfection.
