Abstract: Objectives. This study assessed a strategy designed to contain imported cases of syphilis and prevent reestablishment of ongoing transmission. Methods. Reported syphilis cases during an endemic period (1990-1992) and an elimination period (1997-1998) were compared in San Diego, Calif. The elimination strategy, which focuses on rapid reporting of infectious syphilis cases by clinicians, prompt partner and sexual network management, outreach to marginalized populations, and implementation of an outbreak containment plan, was evaluated. Results. Infectious syphilis incidence rates declined from 18.3 per 100 000 in 1988 to 1.0 per 100 000 in 1998. Of the 46 cases involving probable infection during 1997-1998, 19 (41%) were imported, mostly (79%) from Mexico. Outbreak containment procedures were implemented successfully for 2 small clusters. Outreach workers provided sexually transmitted disease information to a large number of individuals; however, no cases of infectious syphilis were identified, suggesting that syphilis transmission was not occurring among marginalized groups. Conclusions. This syphilis elimination and importation control strategy will require monitoring and adjustments. Controlling syphilis along the US-Mexico border is a necessary component of syphilis elimination in the United States.
