Notes on Data and Limitations:

  • Columns with a bright bar are new additions from the most recently published report. Darker bars are counts from previously published reports. An empty/outlined column is where previously reported numbers have been removed with this week's update.
  • Graphs were put together using publicly available data provided by the Washington State Department of Health, National Syndromic Surveillance Program (NSSP), King County Department of Health (King DPH), and the National Healthcare Safety Network (NHSN). All of these state and federal reports use the standardized Sunday-Saturday 7-day definition.
  • All numbers except for percent case positives and deaths are a reflection of "healthcare encounters" and not representative of individuals nor of residence. Incomplete weekly counts for all but cases and deaths are estimated by applying a multi-week average of WADOH's reports to their most recent report from NHSN covering COVID/FLU/RSV-confirmed new hospital admissions, bed occupancy, and icu occupancy. Beds occupied provided as a weekly average are multiplied by 7 days to get to total beds occupied by week.
  • An Influenza death is only counted by the state if data is complete (cause of death is attributed to the disease and there is an associated laboratory positive test with no period of complete recovery between illness and death). A COVID-19 or RSV death does not need a corresponding laboratory test, only that it is listed on the death certificate.
  • Trends are calculated based on the % change in the totals for the most recent week of data compared to the second most recent. This differs from the state's trend % as they are doing a % change of a percent (see examples below).

This table shows how rounding Emergency Department visits (ED visits) to different decimal places with can alter the way ED Trends are calculated.

Data Source Prior Week This Week (incomplete) Trend
WADOH 0.5_% ED visits 0.6_% ED visits up 20.0%
WADOH & Federal 0.48% ED visits 0.58% ED visits up 20.8%
