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. What is the cause of syphilis?
What is the cause of syphilis phase III
Syphilis is divided into three stages. The first stage is characterized by ulcers and hard scabies in the infected area. The second stage is characterized by skin and mucosal damage and lymph node enlargement. The third stage is characterized by damage to the heart, nerves, stomach, eyes, ears, and gummy swelling. The causes of syphilis can be divided into congenital carriers and acquired infections.
1. Causes of congenital syphilis: Congenital syphilis refers to the transmission of syphilis spirochetes from the mother's blood into the fetus through the placenta after 4 months of pregnancy in a pregnant woman with syphilis, which is known as 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. Pregnant women with early syphilis, whether primary or secondary, are almost affected by untreated infections, with 50% of fetuses experiencing miscarriage, premature birth, death, or neonatal death. 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
How to treat third stage syphilis?
Third stage syphilis also becomes late stage syphilis. Patients with third stage syphilis have skin and mucosal damage, with typical lesions being nodular syphilis rash and gumma. Diseases can occur in the nervous system, cardiovascular system, liver, spleen, and bones in the body, seriously affecting the function of various organs, causing disability and even loss of life.
