Wednesday, December 7, 2022: Due to a data processing error, some Race and Ethnicity data was incorrectly reported on the Disease Activity and Testing section for the past two weeks. This week’s update reflects a one-time correction to that data. This change affects approximately 70,000 cases, or 4% of all COVID cases, across the entirety of the pandemic. Additionally, due to a security breach encountered by one of Washington’s hospital organizations, data about cases, hospitalizations, deaths, and testing are incomplete in some counties from October 2, 2022. This could affect up to 100 COVID cases per day as well as associated hospitalizations and deaths. The issue is likely to last for the next several weeks. We will update this data note as additional information becomes available.
Effective December 7, 2022, Variant information on the Disease Activity section will be updated monthly. The next full update of this information will occur on Wednesday, December 21, 2022.

Every day, acute care hospitals in Washington report their COVID-19 patient occupancy to the Department of Health through WA-HEALTH, a hospital data collection system developed in partnership with the Washington State Hospital Association. The table below shows the total number of hospital beds occupied by patients with suspected and confirmed COVID-19, and a subset of patients on ventilators. This table was updated March 1, 2021, to include suspected as well as laboratory-confirmed COVID-19 patients. Data shown below are the most recent complete data available.
Data shown below are the most recent complete data available.
DOH partners with the Fred Hutchinson Cancer Research Center, University of Washington and the Microsoft AI for Health program to develop modeling situation reports monthly. Previous situation reports in partnership with the Institute for Disease Modeling (IDM) can be found on IDM’s COVID-19 Reports page.
Roadmap to Recovery reports and data downloads prior to March 11, 2021
The following reports have been discontinued. Below are the final published reports.
Effective November 2, 2022, DOH updates the COVID-19 dashboard on Wednesdays only.
Time delays occur in our reporting of laboratory testing data, cases, hospitalizations, deaths, and vaccinations due to processing and reporting differences between data sources including laboratory capacities and case reporting processes. The data reporting is incomplete until we receive 90% of the laboratory tests, cases, hospitalizations, or deaths for the time-period reported on the dashboard.
When health care providers in Washington state (including hospitals, pharmacies, and primary care providers) give a patient a COVID-19 vaccine, they are required to report it to the Washington State Immunization Information System (WAIIS) within 24 hours. Most vaccination data should appear on this dashboard within seven days of vaccine administration.
Health care providers started reporting COVID-19 vaccines to the WAIIS on December 11, 2020, when the first Emergency Use Authorization was given. The J&J (Janssen)vaccine was added to the list of authorized vaccines in February 2021. The first doses of J&J (Janssen) were administered March 3, 2021, and data for these doses was included on the dashboard beginning March 10, 2021. As of October 2021, Emergency Use Authorization was given for children 5 through 11 years of age. As of June 2022, Emergency Use Authorization was given for children 6 months through 4 years of age.
The “doses given” data on the dashboard includes all COVID-19 vaccinations reported to the WAIIS since the first Emergency Use Authorization was given (December 11, 2020). Any doses given to people less than 6 months of age will be excluded from data on people vaccinated. This is based on the current minimum approved age for vaccination and will be adjusted as the approved age expands.
Public health experts agree that the true number of people who have been infected with COVID-19 in Washington greatly exceeds those who have received positive, laboratory-confirmed results. It is very difficult to know exactly how many people in Washington have been infected to date, since a significant number of people with COVID-19 experience only mild illness or no symptoms.
Effective December 16, 2020, case, hospitalization, and death counts include both confirmed and probable cases. Confirmed cases include individuals who received a positive molecular test result for COVID-19. Probable cases are individuals who received a positive antigen test result for COVID-19, but no positive molecular test result. Our dashboard includes antigen test results dating back to June 2020, when these were first reported in Washington.
Case Rate 14-day
The trend in case rate refers to the trend in 14-day rate of new COVID-19 cases per 100,000 population. It is calculated by dividing the number of cases with a specimen collection date during a 14-day period by the state population (county population is used in county view) and multiplying by 100,000:
Case Rate 7-day
The trend in case rate refers to the trend in 7-day rate of new COVID-19 cases per 100,000 population. It is calculated by dividing the number of cases with a specimen collection date during a 7-day period by the state population (county population is used in county view) and multiplying by 100,000:
A “COVID-19 hospitalization” is a Washington resident who is listed in the Washington Disease Reporting System (WDRS) or the Rapid Health Information Network (RHINO) records as hospitalized with confirmed or probable COVID-19.
Beginning April 30, 2021, DOH began using data entered into WDRS to assign the earliest hospital admission date. If an investigator doesn’t provide a hospital admission date, we will use the earliest hospital admission date from RHINO. Prior to April 30, 2021, we assigned the earliest hospital admission date whether it originated from WDRS or RHINO.
Hospitalization Rate
The trend in hospitalization rate refers to the trend in the 7-day rate of new COVID-19 hospitalizations per 100,000 population. It is calculated by dividing the number of COVID-19 hospitalizations with a hospital admission date within a 7-day period by the state population (county population is used in county view) and multiplying by 100,000:
Death counts on our dashboard reflect those in our official vital records database, the Washington Health and Life Events System, where the cause of death was confirmed or suspected to have been COVID-19. If COVID-19 is later ruled out as the official cause of death, we will remove these deaths from our dashboard. We do not report preliminary death information recorded in other systems.
Deaths are reported to the state by health care providers, medical examiners/coroners, local health departments, and others. For this reason, the statewide count of deaths often lags behind the counts of local health departments.
Death Rate
The trend in death rate refers to the trend in 7-day rate of new COVID-19 deaths per 100,000 population. It is calculated by dividing the number of COVID-19 deaths with a death date within a 7-day period by the state population (county population is used in county view) and multiplying by 100,000:
Two important data issues continue to affect results presented on the testing tab:
These issues impact some counties disproportionately. Washington State Department of Health (DOH) continues to work on a sustainable solution.
Trend in Percent Positivity
The trend in the percent positivity metric refers to the percent of positive of tests over a 7-day period. This metric is calculated by adding the positive tests during a 7-day period and total tests (positive and negative) during a 7-day period, then dividing the number of positive tests by the total tests and multiplying by 100:
Trend in 7-Day Testing Rate
The trend in the average daily testing rate metric refers to the trend in the rate of new tests per 100,000 population over a 7-day period. This metric is calculated by adding the tests performed for the most recent 7-day period, then dividing by the population (state or county) and multiplying by 100,000:
WA HEALTH is Washington’s Healthcare, Emergency and Logistics Tracking Hub. Washington’s acute care hospitals use WA HEALTH to submit information to DOH regarding resources available to care for Washington residents.
WA HEALTH is a dynamic data collection system that receives data from hospitals daily as information is available. We consider the most recent 6 days of data to be “incomplete” because it takes up to 6 days for data collection, quality checks, and reporting.
Trend in Hospital Admission Rate
The trend in hospital admission rate metric refers to the trend in new COVID-19 hospital admissions per 100,000 population over a 7-day period. This metric is calculated by adding the hospital admissions for the most recent 7-day period, then dividing by the state population and multiplying by 100,000:
Percent ICU Occupancy
The percent ICU occupancy metric refers to the average percent occupancy of all ICU-staffed beds during a 7-day period. This metric is calculated by adding the statewide ICU capacity for adult beds and occupied beds for each day during the recent 7-day period, then dividing the ICU occupied beds by the total ICU staffed beds and multiplying by 100:
Percent ICU Occupancy by COVID-19 Patients
The percent ICU COVID-19 occupancy metric refers to the average percent occupancy of ICU-staffed beds by adult COVID-19 patients over a 7-day period. This metric is calculated by adding the statewide staffed adult ICU beds and ICU beds occupied by adult COVID-19 patients for each day during the recent 7-day period, then dividing the ICU beds occupied by adult COVID-19 patients by the total ICU staffed beds and multiplying by 100:
Percent Hospital Occupancy by COVID-19 Patients
The percent hospital occupancy metric refers to the average percent occupancy of hospital beds occupied by patients with COVID-19 over a 7-day period. This metric is calculated by adding the statewide staffed, adult hospital beds and the beds occupied by adult COVID-19 patients for each day during the recent 7-day period, then dividing beds occupied by adult COVID patients by the total staffed beds and multiplying by 100:
On September 15, 2021, DOH changed the way we calculate the age-specific rates of cases, hospitalizations, and test results shown on the Demographics tab. These rates were calculated by taking the total number of cases, hospitalizations, and test results reported in each age range and dividing by the total state population. To increase accuracy, we now divide by the number of Washingtonians in each age range. This change resulted in minor changes to existing trends and a one-time, artificial increase in the rates reported across all age groups.
Metrics calculated using population denominators may have changed slightly April 12, 2021. On that date, DOH used Washington Office of Financial Management 2020 estimates to update population estimates on the DOH dashboards (April 1 official population estimates | Office of Financial Management (wa.gov)).
