Syphilis does not usually go directly to stage 2, the condition of syphilis is regular and progressive, and will be transitioned from stage 1 syphilis to stage 2 syphilis.
Syphilis usually begins when the body is infected with the spirochete two to four weeks before the onset of symptoms of stage I syphilis, during which time the patient usually has no systemic symptoms and may have a localized chancre and swollen lymph nodes. The chancre is highly contagious and can last from three to eight weeks or more in untreated cases, leaving a superficial scar on the skin when it subsides.
If a person with stage 1 syphilis is not treated thoroughly, the condition can progress to stage 2 syphilis. Patients with stage 2 syphilis may develop symptoms other than skin lesions. Typically, a syphilitic rash is present, which spreads all over the body and appears as red or maroon papules, macules, and plaques. Patients may also experience patchy hair loss, muscle aches, and swollen joints.
Once diagnosed with syphilis, patients need to cooperate with the doctor to take treatment measures so as not to delay the condition.
