It’s a fact. Anywhere there is a huge spike of deaths and hospitalizations and cases, human behavior changes. Also, immunity increases. The pool then shrinks. I don’t think delta is going anywhere though as the baseline won’t be what it was at it’s lowest point in June but I’ll be very happy if it is and then delta stays down. I think delta won’t stay down until about 6 more months of vaccinations (about 50 million) plus more natural immunity given by Delta
