Symptoms of Primary and Secondary Syphilis

Primary syphilis is characterized by the classic hunterian shanker, a painless ulcer that can develop 10 to 90 days after exposure. Trepidum-apalidum has a propensity for moist areas and so is likely to be found wherever mucous membranes are a frequent site of sexual contact. Penicillin G, administered parentarily, is the preferred drug for treating persons in all stages of syphilis. The preparation used benzothine, aqueous prokane, or aqueous crystalline, dosage, and length of treatment depend on the stage and clinical manifestation of the disease.
