What is the cause of Trichomonas vaginitis?

Trichomonas vaginitis is a common gynecological disease. It is mainly caused by Trichomonas vaginalis parasitizing in the female vagina and causing vaginal inflammation. It is contagious and seriously affects the health of patients. So people will ask, what is the cause of Trichomonas vaginitis?

Direct transmission: through sexual intercourse; indirect transmission: through public baths, bathtubs, baths, swimming pools, toilets, clothing, equipment and dressings, etc.

Trichomonas vaginitis is acquired from external infection. For an infectious disease to spread, there must be three conditions: source of infection, route of transmission and susceptible individuals.

Anyone can be infected with Trichomonas, but those with altered vaginal pH or low immunity are more susceptible to infection. Very few patients can recover on their own after being infected with Trichomonas, and even if they are cured, they can be infected again. The sources of infection of Trichomonas are those who carry the worms and contaminated objects.

As for the transmission route, there are two types: direct transmission, i.e., sexual transmission, and indirect transmission. In foreign countries, vaginal trichomoniasis is mainly transmitted through sexual intercourse, so it is classified as a sexually transmitted disease. In my country, the transmission method is different. Due to the large population in my country, public health facilities are relatively backward compared to developed countries, so transmission in public places has also become an important transmission route. For example, if the seats in public baths or toilets in public toilets are contaminated by the secretions of carriers, then the later ones may be infected if they sit directly on the seats or toilets. The basins of public baths, swimming pools with high density and poor disinfection in summer, wearing other people's underwear, renting swimsuits, etc., may all cause the spread of Trichomonas.

In addition, sharing of bathtubs among family members and medically induced cross-infection are also causes of indirect transmission of Trichomonas.

Gynecological experts suggest: The pathogen of this disease is Trichomonas vaginalis. Trichomonas is a parasite, but it is invisible to the naked eye. This type of Trichomonas is pear-shaped, 10-30μm long, with 4 flagella on the head that are as long as the body of the worm. This type of Trichomonas can be clearly seen under a microscope. Trichomonas has a strong adaptability to different environments. It can grow and reproduce under conditions of 25℃-42℃, survive for 21 days at low temperatures of 3℃-5℃, and can still survive for 20-60 minutes at 46℃. After leaving the human body, it can survive for several hours in semi-dry conditions. Trichomonas not only parasitizes in the hypoxic vagina, but also invades the urethra and paraurethral glands, and even ascends to the ureter and renal pelvis. The most suitable pH value for the growth of Trichomonas is 5.5-6. If the pH is below 5 or above 7.5, the growth of Trichomonas will be inhibited.
