Sex Transm Infect. 2023 Jun;99(4):285-286. doi: 10.1136/sextrans-2022-055704. Epub 2023 Mar 16.


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.

Keywords: HIV; disease transmission, infectious; gastroenterology; homosexuality, male; virology.
