The resurgence in cases also correlates to more universal masking. Maybe the masks made people feel immune and encouraged bad behaviors along the lines of why the original guidelines did not encourage mask use.
The continuous peaks and valleys all in one direction seem to me like manipulated data... for example... does anyone know where the underlying cdc data is available? Why did they only show deaths and cases from the days they were reported and not on the days that they actually happened? I would like to see the deaths data by the dates of the actual deaths, not the dates those deaths were reported. I have a feeling it would tell a very different story.
In some states, it probably also corresponds to the Mostly Peaceful Protests (TM).
The original guidelines did not encourage mask use because there was a real shortage for meeting medical and hospital needs. Once American ingenuity solved the problem by making their own masks they should have been recommending them. Also, why did noone suggest using a scarf or bandana?
