What are the causes of tertiary syphilis?

Syphilis is a very serious sexually transmitted disease that is contagious and popular. It not only harms one's own health, but also harms and harms one's family. Understanding the causes of syphilis can effectively prevent 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: Transplacental transmission of Treponema pallidum mostly occurs after 4 months of pregnancy. Fetal infection is related to the course of the mother's syphilis and whether it 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 rose toy , 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 wand vibrator , advanced syphilis is mainly caused by malformation or chronic damage left over from early infection.

2. Causes of acquired syphilis: It is mainly transmitted through sexual intercourse. Early syphilis: It is highly contagious within 2 years of the disease, including primary, secondary and early latent syphilis. Advanced syphilis: The disease lasts for more than 2 years. The infectivity includes tertiary syphilis and advanced latent syphilis.

When syphilis invades the human body, after an incubation period of 2-3 weeks (called the first incubation period), skin damage (typical damage is hard chancre) occurs. This is primary syphilis. After skin damage occurs, the body produces antibodies. Studies on experimental syphilis in rabbits have proved that the histological feature of the early stage of syphilis is the infiltration of monocytes. On the 6th day of infection, there is lymphocyte infiltration, reaching a peak on the 13th day. Macrophages appear, and the infiltrating lymphocytes in the focus are mainly T cells. At this time, Treponema pallidum is found in the interstitial spaces of epithelial cells in chancre, and in the invagination or phagocytosis of epithelial cells, or in fibroblasts dildo vibrator , plasma cells, Small capillaries between endothelial cells and in lymph vessels and local lymph nodes.

When syphilis develops to stage three, it is already very serious, so you must actively treat syphilis in the early stages.
