Syphilis is a sexually transmitted disease caused by a syphilis spirochete infection that attacks multiple systems and organs in the body. In the early stages of the disease, the chancre may appear as stage 1 syphilis. A syphilis rash is characteristic of stage 2 syphilis.
Six to eight weeks after the chancre subsides, or about seven to ten weeks after infection with the spirochete, a second-stage syphilis rash, or syphilis eruption, can appear, appearing as erythematous blotches, papules, plaques, etc., and can develop all over the body.
