You feel intense itching in the intimate area. Vaginal discharge is abundant, appears in greater quantity before and after menstruation. It is liquid, foamy, greenish and smells bad. You complain of pain during urination and after sex. In the presence of such symptoms, it is most likely trichomoniasis. This disease is the third most frequent reason for the development of inflammation of the vagina. This disease is sexually transmitted and is caused by the single-celled parasite Trichomonas vaginalis. In addition to sexual contact, in very rare cases you can also get infected from contaminated objects such as underwear, toiletries, dirty toilet seats. Infection from water in swimming pools is not excluded. NEWS_MORE_BOX As a sexually transmitted infection, trichomoniasis also occurs in men, but much less frequently. In them, the condition proceeds more like an asymptomatic carrier. Acute infection is still observed even infrequently with the following complaints: scanty discharge from the urethra, burning after sex or mild itching. Trichomonas damages the epithelial cells of the vagina and changes the local acidity; makes it alkaline, with pH 5-8.5 being the optimal environment for the development of the microorganism. The parasite can colonize the vagina for a long time without causing the above symptoms. This means that in addition to an acute infection, there is also a chronic one. The main complaints in chronic carriage are itching and painful sex (dyspareunia). The chronicity of infection from an epidemiological point of view represents the most important source of spread of infection. Therefore, the diagnosis and timely treatment of these cases is important. The diagnosis is made on the basis of the complaints and the isolation of the causative agent. The material taken from the vagina should be immediately placed in special culture media such as Diamond, Trichosel. Once the disease is established, the treatment is carried out by antibiotic therapy with the use of metronidazole 500 mg twice a day for one week. Treatment of partner(s) is imperative.
