Additional information also is available through the Washington State Department’s Risk Assessment Dashboard.

We are updating confirmed and probable case numbers in the table below, as well. Depending on the time of day you check the dashboard and the table, numbers may vary. Please be sure to check the "Data as of" and "Last Updated" note to confirm the most current number.

Additional information is available in weekly reports. The Health District is focusing resources on activities and data analysis that are necessary for disease prevention efforts and to move through the Safe Start Plan for Washington. This includes case investigations, monitoring metrics for quality assurance of that work, and submitting regular reports to the state under the Safe Start requirements.

Cumulative case count Last Updated 2:38 8/14/2020
Confirmed  5,738
Probable 723

Note: Numbers in the table above may not match numbers on the interactive dashboard. The dashboard includes confirmed cases. The table above includes confirmed and probable cases, listed separately. “Probable” cases are close contacts of a confirmed case who become symptomatic or people with positive serology/antibody tests AND a credible history of COVID-like illness. 

Confirmed case counts may vary between the table and the interactive dashboard, as well. New reports of positive tests come in and disease investigations are done throughout the day, so the numbers vary based on the time of day the data is run.
