Yesterday the Seattle Times published a graphic that had a breakdown by age. I will try to find it again a post it but in summary, those between 0 and 59 made up 54% of the confirmed cases. However most of the deaths came from those 60 and above, with each 10-year age bracket increasing in percentage of deaths.
From the Washington State Dept. of Health website this morning
