If you look at places like Arizona, Texas, Florida and Georgia, the reproduction number, Rt, is lower than during lockdown.

Are people somehow practicing social distancing more now than during lockdown? The data doesn& #39;t seem to suggests this.

Immunity is likely a factor.

Separately, California was one of the first states to issue a stay-at-home order, and one of the last to reopen.

Deaths did not significantly decrease during lockdown, and following reopening, deaths more than doubled in the span of 2 months.

On the positive side, states like Ohio, Virginia, Wisconsin, and Oregon are doing a relatively good job at containing the spread. Their death rate per 1M is less than 25% of Florida/Texas/Arizona.

In these states, policy + behavior likely play a larger role than immunity.

I want to avoid the term "herd immunity" because a lot of people have been misusing it (including myself a few weeks ago).

It& #39;s a term rooted in the context of immunity gained from vaccinations, not infections. And it assumes normal behavior, which is not the case here.

9/n
With that said, the data does suggest that a mixture of behavior change + population immunity is responsible for the recent decrease in cases/deaths.

It& #39;s too early to conclude that "behavior doesn& #39;t matter" or "immunity doesn& #39;t play a role".

Lastly, I& #39;ve seen many people on this platform use/misinterpret data to support their agenda or prove that they were "right".

It& #39;s hard to make progress when there are two "sides" and each is unwilling to admit they were wrong.

The truth is often somewhere in the middle.

11/n
As a modeler, I& #39;m forced to constantly update my assumptions and beliefs. If I don& #39;t, then my projections would no longer be accurate.

My hope is that we can focus on finding common ground solutions rather than just trying to prove the other side wrong.
