I apologize that I was not able to send a report yesterday.

Update from Public Health – Seattle & King County

As of 11:59 p.m. yesterday, June, there were 8,235 confirmed cases of COVID-19 in King County, 50 more than the previous day. There have been 560 confirmed deaths in King County due to COVID-19, 6.8% of all confirmed cases.

The numbers that Public Health reports each day include delayed results from previous days.

Observations

The first graph above shows new cases (blue bars) and the 7-day average (red line). Of the 50 new cases reported today, 26 were confirmed yesterday and the remaining 24 were confirmed in previous days. The 7-day average of new cases per day peaked at 194 on April 1. The average for the last 7 days is now 42 new cases per day, up from 33 three days ago. The 7-day average has increased 10% in the last week and declined 24% in the last two weeks. If the rate of decline during the last two weeks continues, the 7-day average will be 10 on around August 12.

The second graph below shows the total case count. With 8,235 total cases as of 11:59 p.m. yesterday, the compound daily growth rate during the last 7 days has been 0.52%, 3 basis points higher than the 0.49% rate during the prior 7 days. With 8,235 cases, the daily growth rate must be less than 0.12% in order for the number of new cases per day to be less than 10.

The third graph below shows the trajectory of cases in King County with the total number of cases on the horizontal axis and the new cases on the vertical axis. Each axis is on a logarithmic scale. Each blue dot represents a daily report. The dot farthest to the left is the February 28 report. Time passes from left to right as the total case count grows. The dot farthest to the right is today’s daily report. We can see a clear change in the trajectory since March 28, shortly after Governor Inslee’s “Stay Home, Stay Healthy” order on March 23.

Thank you for being curious.
