Trust times+means trust is positive, 1: 1, TPPA 1: 2650 means trust is positive, and you have had syphilis before. I don't know how long you have syphilis, and I don't know about your husband's trust and TPPA. After two years, the infectivity of syphilis is reduced, but the possibility of fetal transmission is still relatively high. If you are worried about fetal infection, the possibility of waiting for four years or more will be reduced.
