Babies born with cured mono-positive syphilis are usually not mono-positive, and a pregnancy with cured syphilis will not infect the fetus. A mono-positive syphilis test is usually positive for syphilis-specific antibodies and negative for non-specific syphilis antibodies. This indicates that the patient has been infected with syphilis in the past and has been cured after treatment and is not infectious. At this time, there is no active syphilis in the pregnant woman’s body, which will not cause fetal infection. It is recommended that pregnant women be monitored regularly during pregnancy, and that the titer of non-specific syphilis antibodies be checked every one to two months. After the child is delivered, both the mother and the newborn also need to be tested for syphilis antibodies and titers. It is important to maintain good hygienic habits in daily life to avoid cross-infection, and to use separate household items and clothing. It is also recommended to take proper intake of high quality protein, vegetables, fruits, etc., which can effectively enhance the body’s immunity.
