What's the syphilis titer? It's not contagious.

Syphilis is a sexually transmitted disease caused by Treponema pallidum infection, mainly through sexual contact transmission, mother-to-child vertical transmission and blood transmission. After syphilis infection, Treponema pallidum antibody will be positive for life, but the titer of non-Treponema pallidum antibody can gradually decrease to normal. The titer of non-Treponema pallidum antibody can reflect the activity degree of Treponema pallidum. Therefore, it is not infectious when the titer of non-Treponema pallidum antibody is negative. After infection syphilis should be actively given anti-plum treatment, the first choice benzathine penicillin intramuscular injection, need continuous injection for three weeks, once a week, regular follow-up observation after treatment for 2-3 years, while sexual partners and spouses should be examined and treated at the same time.
