Updated daily between 3:00 pm to 5:00 pm
Data are updated daily in the early afternoon and reflect laboratory results reported to the Washington State Department of Health as of midnight the day before. Data for previous dates will be updated as new results are entered, interviews are conducted, and data errors are corrected.

Many people test positive but do not require hospitalization. The counts of positive cases do not necessarily indicate levels of demand at local hospitals.

Reporting of test results to the Washington State Department of Health may be delayed by several days and will be updated when data are available. Only positive or negative test results are reflected in the counts and exclude tests where results are pending, inconclusive or were not performed.

Updated daily, Monday - Friday
This dashboard provides a snapshot of several useful indicators, or measures, related to COVID-19 activity in our community and its impact on our health and our hospitals. These indicators, along with many other data, are key considerations for reviewing current restrictions on activity, recommendations and precautions to prevent the spread of COVID-19. The indicators help determine if current actions are adequate, need to be strengthened, or might be carefully relaxed.

Updated weekly on Mondays
The dashboard below shows the impacts of COVID-19 on communities of color compared to whites in King County, Washington.

Unemployment in King County resulting from strategies to slow the spread of COVID-19

The Washington State Department of Health conducted the Community Recovery-Oriented Needs Assessment (CORONA Survey) in August & September 2020. The survey focused on how people have made changes to their lives during the pandemic, including how lives were impacted. Respondents were directed to the survey website or to a phone number to answer the questionnaire. The survey was available to answer online in English, Spanish, Vietnamese, Russian, Tagalog, and Somali.

Numbers should be used with caution as this was not a statistically representative survey of King County, although a large number of respondents (more than 9,000 respondents in King County) brought their experiences to the survey.

Case investigation and contact tracing are essential strategies for limiting the spread of COVID-19, along with face coverings, social distancing, handwashing and testing.

Public Health's Case Investigation and Contact Tracing Team calls King County residents who have recently tested positive for COVID-19 ("cases"). And they call people who were exposed to COVID-19 ("contacts"). The phone calls include an explanation of isolation and quarantine guidelines, how to get testing and support services, and collecting information that helps Public Health's infection control programs.

Public Health — Seattle & King County is monitoring changes in key economic, social, and other health indicators resulting from strategies to slow the spread of COVID-19. The metrics below were selected based on studies from previous outbreaks, which have linked strategies such as social distancing, school closures, and business closures to specific outcomes. Individual indicators in the grid below are updated daily, weekly, or monthly, depending on the source of data. Additional data will be added over time.

Public Health — Seattle & King County is monitoring changes in key economic, social, and other health indicators resulting from strategies to slow the spread of COVID-19.

The greater Seattle Coronavirus Assessment Network (SCAN) study is a response to the novel coronavirus outbreak (COVID-19). Since March 23rd, 2020, SCAN has worked in collaboration with Public Health Seattle & King County to deliver and collect at-home COVID-19 tests. The SCAN study is focused on testing people who are experiencing symptoms of COVID-19, and is working to increase testing in underrepresented communities and populations.

The SCAN dashboard provides geographic and demographic information from King County about who is ordering a test kit (individuals, contacts and groups) and may differ from the testing data which includes all final results (positive, negative and inconclusive). Reported positives and positivity rate are a combination of general SCAN enrollment and contact testing results, and are not representative of overall population frequency. There was a pause in testing from May 13th through June 9th, during which time SCAN worked with the FDA to update procedures and certifications.

Data is updated daily, subject to change and may vary across other technical reports due to the specific analyses being performed.
