Syphilis 1:16 Is it contagious?

First of all, the first point, simply test syphilis titer 1:16 positive words, it is not able to determine whether it is more infectious. Second point, syphilis infectivity, one is to see the syphilis titer level, in addition to the syphilis infection time to make a rough inference. Third point, generally speaking, the longer the syphilis infection, then its infectivity is weaker. After more than 4 years basically no infectivity. No matter how much the syphilis titer is. Fourth, if syphilis after standard treatment, syphilis titer from relatively high, such as from 1:128 to 1:16, then that treatment is very effective. Then in this state, its infectivity is basically very weak. Finally, if syphilis infection time is very short, just showed symptoms of syphilis hard chancre, detection of syphilis titer of 1:16, then that its infectivity is still relatively strong.
