MCPS has published new COVID data, it can be viewed here. There are some interesting bits, like the fact that half of all quarantines happened last January! 15,000 quarantines! Fortunately, the numbers fell in February. It also shows how many students and staff there are in each school! There have been 27,000 cases so far. If you click on a specific school, it will show only that school's data. Tilden has had 163 cases so far, yet only 129 quarantines.
This data is from March 7th, 2022.
Wow! I didn't know that!
