Stage II syphilis can be completely cured. Syphilis is divided into Phase I, Phase II and Phase III. Phase I and Phase II are called early syphilis, and the clinical manifestations of Phase II syphilis are mainly syphilitic alopecia, flat warts and red rosacea distributed all over the body. If the titer of the second test is more than four times lower than the first, it proves that the treatment is effective and can be continued at three-month intervals without the need for penicillin treatment again. If necessary, it can be combined with the oral administration of immunity-boosting thymidine enteric tablets or pidomod granules, which can play an auxiliary role in treatment.
