It is too soon to make the assumption we have reached a peak. The peak will come, but the delta infections are very regional. I think it is more likely states with high infection rates will improve and less affected states will become worse. Unfortunately states with high vaccination rates are not going to be immune from delta.
Delta infection rates are going to be significant for some time.We will know the outcome the next few weeks.
Your link doesn't support your statement. If you think it does please explain how. This isn't an explanation that makes sense to me: "Look at the chart in the link. It clearly shows a peak. It has dates."
