(Update-Dave is putting together a new version of this chart that tries to remove the case dump and make the lines easier to follow.). This is a new chart Dave Dixon put together. I thought it would be interesting to see if there is a difference in the rate of change in cases by age group over the weeks of the epidemic. If there were, it might suggest that a new strain, i.e., that dreaded Delta (I thought we put that on double secret probation?), is having a disproportionate impact on one or another age group. What is really interesting in looking at the chart is that there isn’t much difference at all in rates of change, and that is despite vaccination rates being quite different. And we certainly don’t see that Delta is affecting the younger age groups more, in fact if anything it is the oldest age groups. That mid-March blip in older groups is that massive case dump DOH did then. Not from those days but earlier, but no way on the weekly report to figure out when.
