What is the probability of being infected with syphilis needles?

First of all, the probability of being infected with syphilis by a syphilis needle has a very large relationship with the specific situation. Second, if the syphilis patient's needle is such an infusion needle, then the probability of being infected with syphilis is generally very small, because although the infusion needle is hollow, there is no blood inside. However, if it is a blood drawing needle, then there is a relatively high probability of being stabbed. Third, it depends on whether the needle is solid or hollow. If the needle is solid, then it is difficult to attach a lot of blood to the needle, so the probability of being infected with syphilis is relatively small.
