Syphilis is the clinical term for syphilis, a chronic infectious disease caused by the syphilis spirochete, which is mainly transmitted sexually, from mother to child, and through blood. Syphilis is very dangerous, it can invade all tissues and organs of the body, and can cause neonatal syphilis through vertical transmission from mother to child, and sometimes even cause stillbirth, miscarriage, premature birth and other situations. The only source of syphilis infection is the patient with syphilis, and the patient’s skin damage, blood, semen, breast milk and saliva all contain syphilis spirochetes. Therefore, about a month after having high-risk sex, if you suspect you have syphilis, you must go to the hospital for a syphilis-specific antibody test versus a non-specific antibody test.
