Herd Immunity & Social Distancing:

. @alexsalvinews: Compare California to New York: CA declared shelter orders 2 weeks earlier and doesn't see surge.

. @Liz_Wheeler: How do we know it's social distancing that made the difference versus other theories like herd immunity? (1/5)

. @Liz_Wheeler: That doesn't explain why California is not seeing the numbers predicted in these models, which took into account social distancing.

. @alexsalvinews: The models were based on actions taken before. This response is unprecedented, hence why numbers are lower. (2/5)

. @Liz_Wheeler: If there's no evidence, you're mistaking correlation for causation ... Is there evidence that closing down someone's business made a difference?

. @alexsalvinews: You could say we were doing herd immunity before we issued lock-down orders. (3/5)

. @alexsalvinews: Seattle early on was a hotbed for COVID. They implemented distancing orders and saw reported illnesses cut by 1/3.

. @Liz_Wheeler: When you take a state like [Washington] and assume social distancing is what slowed the spread, that's making an assumption. (4/5)

. @alexsalvinews: When you look at all of these places as a whole, you find a common variable that social distancing measures resulted in the fall off of the curve.

. @Liz_Wheeler: I need to see proof not just opinion especially when these models assumed social distancing. (5/5)
