Yikes. Some of these measures seem excessive to me, and I teach Kindergarten! I always make sure the kids wash their hands after lunch and after going to the bathroom. I encourage them to do so and try to teach them the importance of cleanliness. But... that's it. I keep some B&B hand sanitizer in my desk, but it's mostly only for my use. A few of my students bring their own sanitizer, some do not.
