UPDATE: There are now 70 confirmed cases of COVID-19 in Washington state. There’s 51 cases in King County, 18 in Snohomish County and 1 in Grant County. Death toll remains at 10.
The numbers are constantly changing, but by my estimate Washington state would rank 16th in the world (# of cases) if it were a country!:
