Within the first week of passing 10 deaths, Washington deaths doubled every five days. Over the past week, growth rate has slowed, and deaths in the state doubled every nine days.

Dotted lines show the slope of deaths doubling every one, three, five or seven days. CREDIT: Stephanie Adeline and Lauren Sommer/NPR
