medically unheard of

doesn't that just mean that it wasn't confirmed by a professional, noted in some records, and had those records added to a pile from which statistics are drawn?

once upon a time, I was working as a bank teller and my coworkers noticed blood on my forehead, so I went to the bathroom and yep, there was a tiny amount of blood coming out of the pores of my forehead for no apparent reason (no pain, no visible injury, etc).

coworkers made me go to the ER, where I was eventually diagnosed with "a rash" and sent home

I never followed up with anyone about it

did a case of "spontaneous dermal bleeding of unknown etiology" get reported to the local health department that year? did they pass that on to the state? 🤔
