Outbreaks of syphilis have been described among men who have sex with men (MSM) in many western urban communities in the last few years. ⋯ This syphilis outbreak included MSM who were co-infected with HIV and were characterized by risky sexual behavior including multiple partners, unprotected anal intercourse and substance use. Future targeted interventions should focus on HIV-infected MSM for secondary prevention.
