I suspect you will find most hospital toilets are lidless.
Correlation?
Perhaps--but certainly not causation.
There are two things you need for infection: a sufficiently high concentration of the pathogen in question, and a vector for transmission.
Hospitals present much higher concentrations of pathogens in the form of the patients who are already infected with them, and much more effecient vectors. Like doctors, nurses and improperly sterilized instruments.
It also bears noting that by putting lids on the toilets, you are giving the water and the pathogens a place to settle--potentially
increasing their concentration. Pathogens in the air will tend to get disappated through normal air circulation. But by putting the lid down, you are potentially increasing the concentration of them on the lid with every flush--making the matter worse, not better.
Here's an experiment for a budding microbiology student: swab the underside of your toilet seat (both the ring and the lid) and culture them. Leave the seat up for a week, and repeat. Then leave the seat down for a week and repeat. Compare the populations in the cultures and see that you get.
