What are the causes of syphilis? How long is the incubation period for syphilis?
Syphilis is a very serious venereal disease. However, a serious venereal disease not only harms one's own health, but also harms the family and harms the family. Understanding the causes of syphilis can effectively prevent the occurrence of syphilis. So what are the causes of syphilis?
Syphilis can be divided into three stages: ulcers or chancre at the infected site of first-stage syphilis; skin and mucous membrane damage and lymph node enlargement in second-stage syphilis; heart, nerves, stomach, eyes, ears and gum lesions in third-stage syphilis. The causes of syphilis can be divided into two types: congenital infection and acquired infection.
1. Causes of congenital syphilis: Congenital syphilis refers to the passage of Treponema pallidum in the maternal blood through the placenta and into the fetus 4 months after the pregnant mother suffering from syphilis. That is, syphilis occurs during the fetal period and is called neonatal congenital syphilis after birth.
Cause: Four months after Treponema pallidum spreads into the placenta, fetal infection is related to the course of the mother's syphilis and whether she is treated during pregnancy. When a pregnant mother has early syphilis and is untreated, almost all fetuses will be affected, whether it is primary or secondary infection magic wands , and 50% of the fetuses will suffer from abortion, premature delivery, stillbirth, or die during the neonatal period. Survivors develop clinical symptoms at different ages after birth, with early syphilis occurring within 2 years of age, mainly as a direct result of infection and inflammation. After 2 years of age, advanced syphilis is mainly a deformity or chronic damage left over from early infection.
2. Causes of acquired syphilis: Infection mainly through sexual intercourse. Early syphilis: Highly infectious within 2 years of the disease, including primary, secondary and early latent syphilis.
Advanced syphilis: The disease period is more than 2 years. The infectivity includes stage 3 syphilis and advanced latent syphilis.
After syphilis invades the human body, after an incubation period of 2 to 3 weeks (called the first incubation period), skin damage (typical damage is hard under prickly heat) occurs is syphilis. After skin damage occurs, the body produces antibodies. According to research on experimental syphilis in rabbits, the histological feature of the early stage of syphilis is monocyte invasion. On the 6th day of infection lesbian double dildo , lymphocytes infiltrate, reaching a peak on the 13th day ed vacuum pump , followed by the appearance of huge phagocytes. The immersed lymphocytes in the focus are mainly t cells. At this time anal dildo , Treponema pallidum is in the gap between epithelial cells under the hard surface.
By the time syphilis develops to stage three, it is already very serious, and active treatment must be carried out in the early stages of syphilis.
