Questions based from the Public Health Insider blog (September 13, 2022): COVID-19 data dashboards updated to provide simpler, more intuitive view of King County data. These are some common questions people ask about the new COVID-19 metrics and trends pages, with answers from our lead epidemiologists:

The Current COVID-19 metrics dashboard will continue to show information about COVID-19 cases, hospitalizations, and hospital bed use, but in a simpler format. Beyond the Current COVID-19 metrics dashboard, the COVID-19 trends dashboard, and the About the data and Download the data pages, all other dashboards are remaining the same, and the same county-wide data will continue be available for direct download by the public.

The COVID-19 summary dashboard and COVID-19 community level dashboard will be retired as part of this redesign. The most relevant information about hospitalizations, hospital capacity impacts, and reported case rates will be displayed on the new Current COVID-19 metrics dashboard, and all other data from the older dashboards will continue to be available via direct download.

The 7-day average rate is used to adjust for daily variations, which may be large among smaller populations. It is determined by first calculating the 7-day rate for each day in the past 28 days. Then, the average of the 7-day rates for the past 28 days is taken.

COVID-19 data by city (and other geographies) are available on the Data for download page. COVID-19 data by city is no longer shown on the dashboards because the COVID-19 data dashboards are shifting to emphasize COVID-19 community level, which is measured at the county level.

We have removed this visualization because it does not represent up-to-date data. Statewide estimates for effective reproductive number are available from the Washington State Department of Health.
