I'm going to pick on you, sorry just back luck that this is an easy post to pick on.
This is why we cannot have nice things.
I posted about this earlier:
- Masks
- Ventilation
- Testing
- Vaccinating teachers/staff
Do all those things, and when ALL those things are true, you can reduce the distance to 3 feet. Add in some surveillance testing to spot any issue fast and react to complete the picture.
That should be very possible in a classroom. Which is where the impact of 6 vs 3 feet is largest.
Not so much in a cafeteria. Adjusting the guidelines wouldn't be some blanket 3 feet is good enough. If would be specific to the other conditions being there too.
The problem will be, that message and nuance get's lost. We'll see headlines for clicks like "Schools can be 3 feet but your favorite bar is still 6 feet!". They'll bury all the those other steps 5 paragraphs in that nobody ever reads.
This loss of nuance and additional conditions and information beyond the first checkbox and treating everything the same is why we cannot have nice things.
They cannot. But, lunch is only part of school not all of school. The guideline change wouldn't apply while eating lunch.
However, sitting in a classroom is the majority of the day, not eating lunch.
Combined with, a restaurant isn't doing all those other mitigation efforts. It's the total package and how all the elements interact. Ramp up the "not distancing" items and you can relax distance. Eliminate other elements, like sitting at a dining table, and you need to ramp up distance to compensate.
Want to really get them packed into the classroom. Give all the kids bio hazard suits with internal food supply and waste disposal. They could be shoulder to shoulder then with no risk. Probably overkill and cost prohibitive though.
