A daily count of COVID cases is meaningless without knowing how many other kids and teachers tested positive in the previous 5 to 10 days and how that compares to the total population of the school.


...As an example, I live in Montgomery County, Maryland. A week ago, the county announced it would publish daily COVID case counts for each school, then calculate the amount of schools more than 5% positive over a 2 week period, which would trigger the school to go virtual. 

That was clear, responsible use of data they already had. They generated a spreadsheet (unfortunately via pdf) but it clearly showed RED schools, YELLOW, and GREEN. The data not only was understandable, its existence would trigger a set of actions. Great...
