What are the transmission routes of sexually transmitted diseases? Beware of 5 behaviors that spread sexually transmitted diseases

We all know that sex can spread sexually transmitted virus, so only sex can spread sexually transmitted disease? What are the main modes of transmission of sexually transmitted diseases? Why is it susceptible to sexually transmitted diseases? Almost all sexually transmitted diseases are transmitted directly through sexual intercourse. Oral sex, anal sex, masturbation, kissing, touching, etc. It can increase the chance of infection. When an infectious disease is mainly transmitted through sexual contact, it is a sexually transmitted disease. However, sexual contact is not the only way of transmission, but also can be indirectly transmitted through patients' daily necessities, blood and blood products, placenta, birth canal, breast milk, organ transplantation, artificial insemination, etc. There are generally five ways of transmission of sexually transmitted diseases: 1. direct contact with infection 2. indirect contact with pathogens (patients' clothing, appliances, etc.) 3. placental infection Once pregnant women suffer from infectious diseases, they can infect the fetus through vertical transmission (mother-to-child transmission), resulting in abortion, premature delivery, stillbirth, stillbirth or neonatal infection, seriously affecting the health of the fetus. 4. Iatrogenic transmission 5. Direct contact with non-sexual behavior (pathological changes or secretions) and various sexually transmitted pathogens (bacteria, fungi, spirochetes, chlamydia, mycoplasma, viruses, parasites, etc.) causes disease through direct or indirect contact with sexual contact. At present, there are about 25 kinds of infections belonging to STD, including trachoma pathogen, gonorrhea, syphilis, trichomoniasis, herpes, hepatitis B, human papillomavirus, human immunodeficiency virus, soft gland, Denovan disease, venereal lymphogranuloma, mycoplasma, intestinal bacterial pathogens, intestinal protozoa, lice, scabies, and contagious soft warts. Susceptible factors: ③ Endocrine factors: When menstruation is coming, because the pH of the vaginal environment is only 6.8~7.0, gonococcal infection originating from the cervix is also easy to occur, and the probability of upward infection is the highest. ① Anatomical factors: the edge of the junction between normal cervical squamous epithelium and columnar epithelium. It is located outside the cervix, exposed to the vaginal environment, and easy to be infected. In addition, squamous metaplasia is very active in adolescence. Human papillomavirus (HPV) can be integrated during cell replication, so it is easy to be infected with HPV in adolescence. ② Invasiveness of pathogens: Chlamydia trachomatis and Neisseria gonorrhoeae are easy to invade columnar epithelium.
