So I just wanted to know since nobody has been clear with me about when you get syphilis and your titer count is on 1.8 can you transfer it to your Partner and I know for a fact he doesn’t have anything because he got tested. When I first had it back in November I didn’t know I had it till I started getting a rash and I got treated in January for it but my numbers wouldn’t go down so in April or May I got treated again, and I started having sex in June. But every time I get tested it comes back positive. Does syphilis always comes back positive for the rest of your life even if you get treated or should it go away for good?
