(1) A person with a case of infectious syphilis must be instructed to refrain from activities in which body fluids are shared (such as sexual intercourse) until 48 hours after effective treatment has been commenced and must either receive treatment or be isolated until treatment is received.

(2) A person with syphilis must be interviewed by the local health officer or the officer's designee to identify the following types of contacts, depending upon the disease stage in question:

(a) for primary syphilis, all sexual contacts during the three months prior to the onset of symptoms;

(b) for secondary syphilis, all sexual contacts during the six months preceding diagnosis;

(c) for early latent syphilis, those sexual contacts during the year preceding diagnosis, if the time that primary and secondary lesions appeared cannot be established;

(d) for late latent syphilis, marital partners and children of infected mothers;

(e) for congenital syphilis, all members of the immediate family of the case.

(3) All identified contacts of confirmed cases of early syphilis must be examined to determine if they have syphilis, directed to refrain from activities in which body fluids are shared, and, if they consent, immediately be given appropriate treatment. Laboratory specimens must be taken during the examination.
