Trichomonas is not a sexually transmitted disease, as trichomonas itself is just the name of a parasite. However, if trichomonas infection occurs in the human body, especially in the genital tract and urethra, it may be a sexually transmitted disease. From the international scope of STD classification, trichomoniasis, such as trichomonas vaginitis and trichomonas urethritis, which are formed by trichomonas infection, belong to sexually transmitted diseases. However, according to the management of some STDs in China, they do not fall under the scope of national surveillance of STDs. However, in clinical treatment, trichomoniasis should be treated in the same way as sexually transmitted diseases, or in accordance with the standard treatment, mainly through anti-parasitic methods, such as topical metronidazole for worm-killing treatment. At the same time, it is necessary to pay attention to local cleanliness and hygiene to prevent cross-infection or infection through direct sexual contact.
