How to get syphilis

summary

My son more than three months, check out with congenital syphilis, now test report is RPR positive, titer 1, in order to prevent you from this situation, I'd like to introduce how to infect syphilis.

How to get syphilis

First: sexual contact. About 90% of syphilis patients are infected by sexual contact. Untreated patients are the most infectious within one year after infection. With the extension of time, the infectivity becomes smaller and smaller. After 4 years of infection, there is no infectivity through sexual contact.

Second: fetal transmission. Pregnant women with syphilis can transmit syphilis through the placenta. Infection usually occurs after 4 months of pregnancy. Placental infection occurs mainly in the early syphilis of pregnant women, and less in the late syphilis. Fetal syphilis patients, pregnant without adequate treatment, can also be transmitted to their children, the so-called third generation syphilis, but very rare. When the fetus is delivered, syphilis is transmitted through the birth canal, which is not fetal syphilis.

Third: non sexual contact. A small number of patients can be infected by direct non sexual contact with the skin and mucous membrane of syphilis patients. Such as ordinary kissing, handshake, gynecological examination, breast-feeding, etc.

matters needing attention

Leptospira pallidum can be found in the early stage of skin and mucous membrane damage. Treponema pallidum of primary syphilis mostly exists in the hard nodes of chancre, the secretion and exudate of ulcer, and the enlarged lymph node puncture can also be detected. Treponema pallidum of secondary syphilis can be detected in blood and tissues of the whole body, but the detection rate of skin is the highest. In early congenital syphilis, pallidum pallidum can be found by scraping the skin or mucous membrane. Recently, amniotic fluid of pregnant women was obtained by amniocentesis, which can be used as a dark field microscope for the diagnosis of congenital syphilis.
