Wtf is a hand, foot, and mouth disease?

I had only heard of kids having it until last year when my niece’s boyfriend had it. He had blisters all over his lips. I think it’s pretty painful

It's a weird viral infection; you kinda sorta have to get it on purpose, but not exactly to the point of seeking out the virus specifically (you'll get something worse instead-I guarantee it). Ignoring/not having access to common hygiene and/or being immunocompromised, as well as having a living/working environment that's moderately unsanitary (or worse), makes it more likely to acquire the virus. Like I said, a weird one, like that one shareware title that never got a full release but we all wanted it to.

Addendum:
It's often mistaken for Ringworm; Ringworm is a fungal infection.

Coxsackievirus infection. It's a nasty little virus, usually gets kids but can affect adults (those who don't wash their hands).

Its a kind of disease that gives you a fever along with blisters on hands and feet. Weird though as it usually happens to children. Is your coworker perhaps a little child in disguise?

Ma'am, I do not know.
I am not a medical professional.
I have only had Athlete's Mouth.

Stay away from her work station. 🤭
