Once again incorrect, the CDC has actual proven Science and Data to dispute your claim its a majority isolated to the kitchen.
However just answering your direct question. Exposure limited to a small subset of the restaurant, a few dozen people at most, compared to the potential thousands via opening up the restaurant for full dining. Yes I'd rather have just the kitchen of a restaurant open for takeout/delievry with full constant testing rather than the whole dining area.
The CDC didn't prove anything about outdoor dining. I'm not sure where you got that from. If the CDC had proved any of that, it would have been used by the county legal teams in their court cases they lost.
Los Angeles County, the nation's most populous at 10 Million and one of the wealthiest communities on earth with a GDP the size of Switzerland, presented what evidence they had on the data collected from Covid transmission in restaurants. And they failed.
The same basic scenario played out a few weeks later for San Diego County, and they also lost their court case with a different judge and different legal teams. They had no scientific evidence to prove restaurant dining spreads Covid more than other industries.
There is almost a full year's worth of data now collected on Covid. Here are three large, wealthy, diverse Sunbelt states who had very different approaches to locking down and opening up. Texas and Florida have allowed indoor dining for many months, California has not allowed indoor dining in many months and even blocked outdoor dining over the past few months. They are shockingly close to one another on the cases per 1 Million metric.
As of Tuesday, February 9th...
Confirmed Cases Per 1 Million State Residents:
1. North Dakota = 128,879 Cases Per 1 Million
24. Texas = 87,386 Cases Per 1 Million
25. California = 86,874 Cases Per 1 Million
28. Florida = 83,728 Cases Per 1 Million
50. Hawaii = 18,776 Cases Per 1 Million
That's all there is to it. Just pure science and data, not opinion, just facts.
