Mardi Gras starts in earnest in Mid Feb - Fat Tuesday is March 1.
I think this is a preemptive move to try and blow the curve sooner.
However, here is what i have heard from Tulane....they are already seeing a downward trend in positivity. SLIGHT but downward. I think i had posted here back in December that their modeling showed peak 3rd week of January for current wave. If that holds, then by mid Feb we should be seeing mad reduction in positivity.
So i think this mask mandate is to curb that peak just a tad sooner to be CLEAR for Mardi Gras 2022.
Just my opinon.
