Which is more serious, syphilis or HPV?

First of all, syphilis infection and HPV virus infection do not matter which is more serious, this is meaningless, because which infection may develop to a more serious stage. The second point, syphilis if not after standard treatment, or even ignored, let it develop on its own, then it may progress to advanced syphilis, thus causing syphilis infection of the nervous system, or syphilis infection of the cardiovascular system, or syphilis infection of the bone, the consequences are more serious. Therefore, if these two infections are not intervened and treated, they may develop to a more serious stage.
