We describe a rare case of severe disseminated monkeypox (MPox) virus infection complicated by peritonitis in a 44-year-old man living with well-controlled HIV. The patient was successfully treated with tecovirimat without requiring surgery. MPox should be considered in the differential diagnosis of non-bacterial peritonitis in patients at risk of infection.
