COVID-19 in King County WA – May 26 Report

by | May 26, 2020

Update from Public Health – Seattle & King County

Public Health has updated the data dashboard. As of 11:59 p..m yesterday, May 25, there were 7,896 confirmed cases of COVID-19 in King County, 17 more than the previous day and 199 more than the last report I sent you on Friday. There have been 544 confirmed deaths in King County due to COVID-19, 6.9% of all confirmed cases.

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


I suspect that the Memorial Day weekend caused some additional delays in case reporting, so we might expect the new cases reported during the last several days to be revised upward during the next few days. The graphs and observations below rely on the data as they stand today.

The first graph above shows new cases (blue bars) and the 7-day average (red line). Of the 17 new cases reported today, 12 were confirmed yesterday and the remaining 5 were confirmed in previous days. The 7-day average of new cases per day peaked at 193 on April 1. The average for the last 7 days is now 36 new cases per day, the lowest level since March 11. The 7-day average has declined 35% in the last week and 51% 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 June 19.

The second graph below shows the total case count. With 7,896 total cases as of 11:59 p.m. yesterday, the compound daily growth rate during the last 7 days has been 0.46%, 28 basis points less than the 0.74% rate during the prior 7 days. With 7,896 cases, the daily growth rate must be less than 0.13% 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. The downward cascade of blue dots is quite pronounced for the last two weeks of data.
