Socialization IS a major cause. Also totally avoidable. Just meet people outside and wear masks. Or play online games and talk over discord/zoom.All true.
But you were trying to ascribe blame for the outbreak to socialization. Yes, it contributed to an increase. The indoor dining didn't because of the dining being closed. What's driving the current outbreak is work.
And it's not just the 1 contact at the chicken processing plants. It's the guy raising the chicken with his staff, the guy delivering the chickens to the processor, the chicken processing plant (all of whom are working in masks BTW), the sandwich truck feeding the processors during lunch, the guy delivering the chickens to the factory, the factory that prepackages the chicken in the 11 herbs and spices, the guy delivering the finished chicken to the restaurant, the chicken restaurant staff, and the clueless guy that walks up to the counter and asks what's good here. These folks then go home, including to some families with grandma watching the kids (who aren't in school) so that they can go to work. Meanwhile, we're all here being key board warriors (while not practicing law or teaching math) and wondering why we are having outbreaks....not to mention that these guys are probably socializing while having a cigarette break given they don't have a Tom Cruise to rant at them.
The other change is that socal has a new variant. Went from 0% in late summer to 50% of cases today. (Likely more contagious.) Today's NYT.
