COVID-19 Dashboard Overview

On August 5, 2022, the Washington State Department of Health (WA DOH) released an updated version of the Requirements and Guidance to Mitigate COVID-19 Transmission in K-12 Schools and Child Care. The updated guidance from WA DOH requires notification to staff, students and their families when there are cases and outbreaks in schools. The Bellevue School District maintains an online dashboard for this purpose. COVID-19 cases for the 2022-23 school year are located on the COVID-19 Cases in Schools Dashboard, with data updated daily at 7:00 a.m.

Current COVID-19 Dashboard – Frequently Asked Questions

How accurate is the information on the dashboard?

The dashboard shows all COVID-19 cases that are reported to the district. Like other COVID-19 dashboards available locally and nationally, reported COVID-19 numbers may be under-counted for a variety of reasons:

• The data from the most recent 3-5 days is incomplete, as it takes time for test results to be returned and reported.
• Not everyone who has been exposed to COVID-19 or has symptoms chooses to get a COVID-19 test. Some students and staff choose to follow quarantine or isolation procedures instead, without testing.
• Not all positive cases are reported to the district.
• Some people with COVID-19 never have symptoms, and so do not get tested.
• Data entry errors are possible, such as positive cases being reported but not accurately logged through the reporting system.

How often is the dashboard updated?

The dashboard is generally updated once a day around 7 a.m. The latest refresh date is shown at the bottom left of the screen.

Why is there a “three-day lag” in the case counts for the last seven days?

We exclude the most recent three days in the “Cases over the Last Seven Days” because these data are incomplete. It takes time for test results to come back and for cases to be reported and entered in the system. Adding a three-day lag helps the count reflect more complete data.

Why is there a wave-like pattern to the graph showing COVID case counts?

People are less likely to get COVID-19 testing on weekends, so there is often a drop in case counts on Saturdays and Sundays, as well as on holidays.

Why do previously posted numbers sometimes change?

We post results as they come in, and it may take several days or more for test results to come back. The counts on the dashboard reflect the date a test was conducted; we update prior date counts whenever new positives are reported, based on the date the test sample was collected.

How can I see case counts over time for a particular school?

Click on the school name in either the column graph (in the middle of the dashboard) or the table (at the bottom of the dashboard). The “Reported COVID Cases Over Time” (top graph) will change to show just cases for that school.
