> Our findings contribute to a growing body of literature which suggests school-based mask mandates have limited to no impact on the case rates of COVID-19 among K-12 students.

As expected.

Simply put, as the science now states, the majority of masks weren't worth wearing. If it's not a KN95 or better, it's all but pointless. That is, you're effectively wearing no mask at all.

We know this. Yet occasionally mask mandates kick in again, and the updated science (i.e., KN95 or better) is completely ignored.

The disconnect - and those virtue signaling with subpar masks - is disturbing.
