Characteristics of repeat syphilis infections and interinfection intervals in a retrospective clinical cohort: implications for syphilis retesting and prevention
Among MSM, syphilis reinfections were common, especially among PLWH and HIV-negative PrEP users, with the latter having the shortest interval between infections. These groups should be retested for syphilis with frequent serological screening, <i>Treponema pallidum</i> PCR testing of syphilis lesions and should be targeted for syphilis prevention.
