C. Incubation period: Usually 3 weeks, ranges from 10 days to 3 months for primary symptoms. D. Period of communicability: Moist mucocutaneous lesions of primary and secondary syphilis are infectious. However, it is difficult to differentiate between the infectious stage and the noninfectious early latent stage.
If untreated, an infected person will progress to the latent (hidden) stage of syphilis. After the secondary-stage rash goes away, the person will not have any symptoms for a time (latent period). The latent period may be as brief as 1 year or range from 5 to 20 years.
