This is exactly the sort of event that would allow those infections to spread.
I also admit to spilling on the seat occasionally myself. When I do, I ask for something to clean with. The Flight Attendants always are helpful.
This story is really messed up, but merely "finding" the floor soaked in blood is only the beginning of the story. It was blood and feces, from a prior passenger that seemed to have exploded in the seat.
Who knows what danger they put this passenger in by making him clean it up.
