from 9.25 to 12.5 deaths per week is significant... but 3 more deaths across the entire west coast is fairly small.
without a comparison to same period last year, there is no discounting yearly trends. maybe that time of year is when the pollen count drastically increases, causing problems. maybe is was unusually rainy. maybe the preceding weeks were unusually low and the subsequent weeks were back to normal.
you can make statistics say anything you want... knowing the answer you’re looking for ahead of time, makes it easier to find.
Ye gods! In the face of huge infrastructure destruction, I'm surprised it's not a lot higher. I'm sure that hospitals and other healthcare delivery mechanisms were much damaged if not outright destroyed. And the numbskulls want to blame it on radiation??? Ridiculous!
