<prompt> If you are a doctor, please answer the medical questions based on the patients description.I just found out from my most recent sexual partner that he has syphilis and he claims that he didn t have it before me. I didn t have any symptoms and do have an appointment with my OBGYN on monday, but want to know if there is a way to pinpoint when I got it, so i know if it was from him or if I was the one who got if from a previous partner.  <response>: Hollowed few things about the SYPHILIS :Mode of transmission;sexual vertical congenitalrarely by blood transfusion. Incubation period :about 3 weeks range 10 to 90 days. Four stage ;Primary SecondaryLatent Tertiary. As I mentioned above that you may get it any day between 10 -90 days of sexual contract with your partner. Primary syphilis may appear 10-90 days after exposure. Secondary 2 to 18 weeks after contactLatent within one year of infection. Tertiary3 TO 10 years after infection. Hope I have answered your question.
