Oral sex with confirmed syphilis case

[onnthelamm]

I am a 35-year-old gay male who recently performed oral sex on a man who went on to tell me two days later that he had been diagnosed with syphilis. I am due to see the Sexual Health Service on Monday, when it will be about 10 days post-exposure. So far I have not noticed any sores or other symptoms in my mouth, although I am extremely stressed as I have a partner who does not know that I was unfaithful.

My questions are:
- How contagious would I be in the first 10 days after contracting syphilis, assuming I have contracted it?
- I'm assuming that I will receive treatment on Monday; how long after treatment will I need to wait before I can safely consider myself to be non-contagious?

Hi syphilis is only contagious when making rubbing contact with an active syphilis chancre. so if you dont have one your not contagious. testing would be at the 6 week mark.  but if he did not have any chancre on his penis you did not contract it anyway.
The only other  time its contagious is in second stage syphilis when there are white  rashes on the feet and hands and actually this it most contagious time.

Thanks Dave. Does that mean that even if someone is in an infectious stage but doesn't have symptoms (i.e. no chancre, or no rash) then there's no way to pass it on?
