Investigation of Early Syphilis Trends Among Men Who Have Sex With Men to Identify Gaps in Screening and Case-Finding in Baltimore City, Maryland

摘要

Background Syphilis incidence is increasing across the United States among men who have sex with men (MSM).

To inform syphilis control strategies and identify potential gaps in case finding, we described recent syphilis trends among MSM and compared characteristics of syphilis cases by diagnosis stage.
