Syphilis initial symptoms, what symptoms are there

Syphilis is an infectious disease. It can be divided into primary syphilis, secondary syphilis and tertiary syphilis. Generally, the initial symptom of syphilis is hard chancre, which often occurs in the genital area and presents painless ulcer. It will disappear 3-6 weeks after infection, but syphilis will spread to the whole body along the lymph nodes near hard chancre, and then enter secondary syphilis.
