摘要

Among 614 men who have sex with men in San Diego County with early syphilis during January 2004 to June 2007, 74 (11.7%; 95% confidence interval: 9.3%-14.4%) had repeat syphilis within 2 years. HIV-infected MSM were more likely to have repeat syphilis (odds ratio: 1.9; 95% confidence interval: 1.1, 3.4). During 1999 to 2008, cases of early syphilis (including primary and secondary [P and S] and early latent [EL] syphilis) in San Diego County increased over 1000%, from 47 to 524. During that time, cases among men who have sex with men (MSM) increased over 2800%, from 14 to 411, accounting for 76.6% of cases overall in the County (County of San Diego, unpublished data).
