Droplets, like those aerosoled out from the flushing of a toilet.
The toilet may be the Achilles Heel to to the safety of humanity.
Oh wait...
I’ve a patient in the hospital, urinated only, flushed the toilet, and seen bits of feces - not mine - wash back into the toilet. I’ve felt the mist from that powerful jet. Of course the toilet had no lid to shut during flushing.
Flushing technique for an agile patient - extend leg, flush with foot, run.
And hospital administration wonders why C-diff spreads.
I don’t work in a hospital now, but when I was in nursing school, I had to empty bedpans. There is a spray arm on the toilets that pulls down to rinse out the bedpans. Powerful spray, and you can’t control the strength. So you get a scoured-out bedpan, yay, but you also get a mist on the nurse’s, or aide’s, skin and clothing.

Toilets and sewage treatment have saved millions of lives. Badly-designed toilets may have killed thousands.
