The source I use for this stuff is Jeff Asher - for whatever its worth his data shows that cases in Orleans have already peaked. I think we are about to see a South Africa-like downslope.
Anyway, our city is one of the most vaxxed and boosted places in the South and we can see pretty clearly from [pick an example - DC, NYC, etc.] that mask and even vaccine mandates do jack squat for omicron. Even CDC is signaling that cloth masks are basically useless at this point. An Orleans mask mandate is really only going to cause disruptions to 2 years worth of pent-up Mardi Gras plans without any benefit to public health. Or maybe send some of those events to Jefferson Parish as happened this summer.
Its counterproductive theater. But I am hopeful that maybe this is when the City will finally say "nah we're good.'
