Eligibility Criteria:
Inclusion Criteria:~* The subject is 18 to 55 years of age.~* The subject has signed written informed consent.~* The subject has untreated primary \[darkfield or Treponema (T.) pallidum by a rapid, direct, fluorescent antibody darkfield (DFA-TP)\] positive genital ulcers, secondary (based on classical palmar/plantar rash, condylomata lata, mucous patches, etc. or darkfield or DFA-TP positive lesions), or early latent syphilis (e.g., current reactive serologic tests for syphilis (STS), and a documented non-reactive STS or documented sexual exposure to a known early latent, primary or secondary syphilis patient in last 12 months; identification of this sexual contact must occur within 60 days of admission into the study).~* The subject has laboratory evidence of syphilis, i.e., reactive serologic test for syphilis (RPR).~* The subject is not pregnant, as documented by a negative urine or serum pregnancy test, or lactating.~* The subject is willing to have an HIV test, and, participate in HIV counseling and return to the clinic for follow-up treatment.~Exclusion Criteria:~* The subject does not have reactive serologic tests for syphilis.~* The subject has latent syphilis of unknown duration, late latent syphilis or evidence of neurosyphilis.~* The subject has a known or suspected allergy to macrolide or azalide antibiotics.~* The subject has a known or suspected sexually transmitted disease (STD), other than syphilis requiring treatment with a drug, other than azithromycin, active against T. pallidum.~* The subject has used antibiotics active against T. pallidum in the preceding 30 days. (Note: the use of antimicrobials known to NOT be effective against T. pallidum such as quinolones, sulfonamides, trimethoprim, metronidazole and spectinomycin will be allowed).~* The subject is known to be HIV positive prior to enrollment.~* The subject has suspected or known ongoing drug use that might interfere with study participation and follow-up treatment.~* The subject has a history of cardiovascular disease, known immunosuppression, or known AIDS, which might compromise response to therapy.~* The subject is judged by the investigators to be unlikely to reliably participate in the study follow-up.~* The subject has used any investigational drugs in the past 30 days.~* The subject has any other condition that may impair drug absorption (malabsorption syndrome or active peptic ulcer disease).
