<CopyPasta from the last three times COVID was declared over and I told you it wasn't> Nothing is over, stockpile, and deploy appropriate NPIs for personal protection since there will be no attempt at collective mitigation measures until it's too late for them to be effective.

Well sealed N95 masks work, have elastomeric masks in case of shortages or high-risk environments, approximate that risk with CO2 meters. If you have control of infrastructure increase ventilation, utilize Upper Room UVGI and HEPA filters. Stockpile dry goods.

A lot of the math has changed. Two-way mask protection is not a factor in many places. If I have to get on a train with 100 maskless people I'm wearing an elastomeric P100 with a valve, they won't protect themselves from each other, I can't protect them alone.
