It's just accepted that kids spread germs to each other. Why? Why isn't anything done to reduce it? Hand sanitizer in classrooms the way they have it in hospital would be a good start. Ensure the kids gel their hands coming into classrooms. No outdoor coats indoors. Proper antiseptic hospital cleaning of the bathrooms at the end of the day.
It just seems bizarre that the attitude is that's just how it is when there are ways of addressing it. Immunocomprosinsed people exist and this is a real problem
