Syphilis is a very serious and serious sexually transmitted disease, which not only endangers one's own health, but also harms the family and harms the family. Understanding the causes of syphilis can effectively prevent its occurrence. So what are the causes of syphilis?
Syphilis can be divided into three stages. The first stage involves ulcers or chancre at the site of syphilis infection; Skin and mucosal damage and lymph node enlargement in secondary syphilis; Phase III syphilis involves the heart, nerves, stomach, eyes, ears, and gum swelling damage. The causes of syphilis can be divided into two categories: congenital transmission and acquired transmission.
1. The etiology of congenital syphilis: Congenital syphilis refers to the transmission of Treponema pallidum from the mother's blood through the placenta and into the fetus after 4 months of pregnancy, which is called congenital syphilis in the newborn.
Etiology: Four months after the transmission of Treponema pallidum in the placenta, fetal infection is related to the course of syphilis in the mother and whether treatment is given during pregnancy. When syphilis occurs in the early stages of pregnancy and is not treated, whether it is a primary or secondary infection, almost all fetuses are affected, with 50% of fetuses experiencing miscarriage, premature birth, stillbirth, or death in the neonatal period. Survivors exhibit clinical symptoms at different ages after birth, with early syphilis occurring within the age of 2, mainly as a direct result of infection and inflammation. After the age of 2, it is late stage syphilis, mainly caused by deformities or chronic damage left by early infection.
2. The cause of acquired syphilis: mainly through sexual intercourse infection. Early syphilis: The disease has a strong infectivity within 2 years, including primary, secondary, and early latent syphilis.
Late stage syphilis: The disease lasts for more than 2 years, and the infectivity includes stage 3 syphilis and late stage latent syphilis.
After syphilis invades the human body, it undergoes a latent period of 2-3 weeks (referred to as the first latent period) and causes skin damage (typical damage is subdermal heat rash), which is syphilis. After skin damage, the body produces antibodies. According to the research on experimental syphilis in rabbits, the histological characteristics of syphilis at the initial stage are monocyte invasion. Lymphocyte infiltration on the 6th day of infection, and the peak occurs on the 13th day, followed by giant phagocyte. Lymphocyte infiltration in the focus is dominated by t cells. At this time, syphilis spirochete is in the epithelial cell gap below the hard surface
When syphilis reaches its third stage, it is already very serious, and active treatment is necessary in the early stages of syphilis.
