I'm betting he has both monkeypox AND a bacterial infection.

Systemic prodromal symptoms may also be mild, absent, or appear concurrent with rash. Secondary bacterial infection of the skin and lungs may occur. Clinical differentiation of monkeypox from smallpox and herpesviruses such as chickenpox or herpes simplex virus (HSV) may be difficult. Additionally, the diagnosis of HSV or another sexually transmitted infection does not exclude coinfection with monkeypox.

He could have syphilis, chlamydia, gonorrhea, MRSA, or the thing that makes your junk fall off -- gangrene -- along WITH his monkeypox.
