SYPHILIS IN SAN-DIEGO COUNTY 1983-1992 - CRACK COCAINE, PROSTITUTION,AND THE LIMITATIONS OF PARTNER NOTIFICATION

Background and Objectives: Recent epidemics of syphilis have been asso ciated with crack cocaine use and anonymous sex for drugs, suggesting a potential limitation of sex partner notification as a disease contro l strategy To assess these factors in an inner city epidemic of syphil is in San Diego County, California, we performed a descriptive epidemi ologic analysis. Study Design: Descriptive epidemiologic data were obt ained from case investigation reports of primary and secondary syphili s. Results: In the middle and late phases of the epidemic (1990-1992), the incidence of syphilis in the inner city area was more than six ti mes that in remainder of the county. Illegal drug use was reported by 30% of patients. Drug use, especially crack cocaine, was related to pr ostitution. The estimated total number of sex partners per patient rat io was 4.2, whereas the named sex partners per patient ratio was only 1.5. Twenty-two percent of patients did not report any named partners. Overall, only 26% of the estimated total number of sex partners recei ved treatment. Conclusions: Expanding partner notification to include more high-risk persons identified through social networks and increasi ng screening among high-risk populations may improve control of inner city drug/prostitution-related syphilis epidemics.
