Should people with germs on their clothes and hands be visiting the hospital?

So, what do you all think? Should we really be letting all these unclean people into the hospital? They come in straight off the street, after handling money at the store, using public restrooms, getting in their dirty cars, picking their boogers while waiting at the light. They haven't been trained in handwashing or universal precautions, and who knows where those hands have been.

Have we really stopped to reflect on the effects that our loose visiting policies have on our patients? What about those grubby little kids running the hallways, touching the walls and handrails, doorknobs, and crawling on grandma's bed. And then, if grandma comes down with MRSA during her hospital stay, who is to blame? Why, the nurses naturally.
