No more data

July 27, 2023: The data sources I was using for this site are no longer being updated. The only remaining sources seem to be sewage data; CDC has it but it’s all relative (Covid levels in sewage versus the highest at any point at that site, but sites came online at different times). Biobot Analytics has data on absolute numbers through time (as well as variants) but they no longer have freely accessible raw data. Even hospitals release data only sporadically and incompletely now. I might poke around later to see what’s available but for now I’m not updating this site.

Old site

What percentage of students in a school have gotten covid over the 2021-2022 year alone? Note that this assumes each student gets covid no more than once. However, a bout of covid gives only partial immunity, so some students may have had covid more than once.
