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.
Latent syphilis is defined as having serologic proof of infection without symptoms of disease. It is further described as either early (less than 1 year after secondary syphilis) or late (more than 1 year after secondary syphilis) in the United States.
