Sustained Mpox Proctitis with Primary Syphilis and HIV Seroconversion, Australia

Abstract

A 26-year-old man in Australia who has sex with men had severe perianal ulceration, proctitis, and skin lesions develop. Testing revealed primary syphilis, mpox, and primary HIV infection. Recent publications have documented severe mpox associated with HIV infection. Disruption of mucosal integrity by mpox lesions could enable HIV transmission and vice versa.
