Human mpox co-infection with advanced HIV-1 and XDR-TB in a MSM patient previously vaccinated against smallpox: A case report

Abstract

Mpox is a zoonotic infectious disease caused by the mpox virus (MPXV). Historically, the majority of mpox cases have been documented in Central Africa. However, since May 2022, there has been a notable rise in reported cases from regions beyond Africa. Currently, over 110 countries spanning Europe, North America, South America, Asia, and other territories have reported mpox infections. This report details a case involving a patient who identifies as a man who has sex with men (MSM) and is concurrently infected with MPXV, human immunodeficiency virus type 1 (HIV-1), Pneumocystis jiroveci, as well as extensively drug-resistant tuberculosis (XDR-TB). This patient had also received a vaccination for smallpox in the past. Additionally, we provide photographic documentation charting the progression of dermatological manifestations associated with mpox. This case highlights the significance of sexual intercourse as a crucial mode of transmission for mpox. The rapid and widespread dissemination of the MPXV across various regions, especially among MSM communities, underscores the importance of enhancing preventive education efforts targeted at high-risk populations.
