Americans could scarcely be blamed for feeling confused about whether or not to wear a mask right now.

Then on Monday, a federal judge in Florida struck it down. Meanwhile, some local governments and private employers are reasserting mask mandates in response to rising COVID-19 transmission rates because of virus variants.
