summary

A good friend of mine told me a few days ago that she had syphilis, which may be caused by the disorder of her sexual relationship. Let's talk about the causes of false positive syphilis antibody.

Causes of false positive syphilis antibody

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.
