Staging of Syphilis infection in an individual is used to determine treatment, when a person was exposed and to identify and treat infected persons limiting the spread of the disease. Using symptoms and titers, the stage of Syphilis can often be determined. A Syphilis lesion indicates a primary infection. Average incubation of Syphilis to the onset of a primary lesion is 3 weeks. Determining the date of the midpoint of a lesion, one can estimate the date of exposure 3 weeks prior to the midpoint date. When secondary Syphilis symptoms are observed (i.e. a Syphilis rash), determine the onset date of the sypmtoms and calculate four weeks prior to the onset which is the average latency period between primary and secondary Syphilis. Then, count 3 weeks back from that date to cover the average time period of a primary lesion. During that 3 week period, the person was infectious. From the midpoint of the 3 week period, counting 3 weeks prior to the midpoint, this person was infected with syphilis either from a primary infection of another person or an infectious secondary symptom of another person. With information about sex partners symptoms, on can determine the source and the spread of Syphilis in a sexual network. Untreated Syphilis titers can provide evidence to the stage of the disease as well. A rising titer (RPR) of two-fold increase indicates a possible new infection. []
