Can you catch anything from sweat?

I feel like this may be a silly question, but I never really thought about it until I started at my new job.
I clean up a lot of sweat. I also have to be barefoot, so sometimes I step into the gross sweat..gag
I’m not talking about just me though. Let’s say I didn’t clean the equipment properly? Or someone didn’t thoroughly clean a tanning bed that someone else was about to lay in (just sweat, not from anything else)

What, if anything, can you get?
I’ve read a lot of medical type books, but have never read anything about this.
