Hello,
Yes. The infection rate is dropped but we cannot rule out that syphilis has gone from your body as of now. This is because TPHA will be positive in old treated syphilis also. Your count says it is still strongly positive, so do a VDRL titer test to assess the present rate of infection.
Take care. Hope I have answered your question. Let me know if I can assist you further.
