Syphilis is a sexually transmitted disease, mainly infected by unclean sex. It is not infected in normal life. If you have a lover who has syphilis, you should also have syphilis. During pregnancy, endocrine changes may affect false positive results. No matter whether you are diagnosed with syphilis now or not, you can take preventive injections of benzathine penicillin, which can be cured. Don't worry too much. Some infectious underwear should be washed separately, not together with family clothes. After a period of time, you can check it again. Generally, it will not affect the baby after recovery.
