Since the active cases in Anne Arundel County Public School students have increased since Thanksgiving, I was curious about the percentage of students with active cases by age range. The rates chart below are just estimates because the total number of students is from the prior year (2020-2021) and the case data has extra categories (i.e. charter/contract, other, and specialty centers). As you can see, rates for all school types stayed below 0.4% until mid-December, when all rates increased sharply. The rate for high school students increased the most, up to 0.8% on December 15.
