COVID-19 Cases in Schools Dashboard (New)

Bellevue School District has updated our COVID-19 Dashboard to better meet the needs of our community. Through the use of PowerBI, the dashboard provides users the ability to look at BSD’s COVID-19 data in a variety of ways, including tables and graphs. Users can also easily change views between district totals and individual school totals. Directions on how to use PowerBI can be found in the How to Use the Dashboard section below.

The information on PowerBI will vary from what has been reported previously, so numbers in the updated dashboard may not match historical information. This is because of a change to the metrics that are being reported on. To provide additional clarity about these changes, below are answers to some frequently asked questions related to BSD’s dashboard and information on what is available through the PowerBI interface.

Frequently Asked Questions


What is displayed on the COVID dashboard?

There are three main pieces of information that are provided on the updated COVID dashboard: positive individuals, quarantines, and transmissions.

  • Positive individuals on the dashboard refers to individuals who fall into one of the following categories:
    • Received a lab-confirmed positive COVID-19 test result
    • Had COVID symptoms after a confirmed close contact exposure, but chose not to test
    • Had a positive COVID antigen test
      -AND-
    • Were in a Bellevue School District facility for a BSD sponsored event during their infectious period.
      • This data includes staff and students, as well as visitors, volunteers, student athletes, or others that were on a Bellevue School District campus during their infectious period.
      • When these individuals become known, trained Bellevue School District staff conduct a contact trace.
  • Quarantines on the dashboard refer to individuals who are unvaccinated close contacts of an infected person that were identified through a Bellevue School District contact trace. Per public health agencies, these individuals must quarantine for a minimum of 7-10 days, depending on whether the close contact participates in testing and the results of those tests. More information on quarantines can be found on our Responding to Cases and Suspected Cases
  • A COVID-19 transmission is reported on the dashboard when, in consultation with public health, all the following criteria have been met:
    • There are two or more lab-confirmed positive COVID-19 cases among individuals.
    • The cases have a symptom onset within a 14-day period of each other.
    • The cases are epidemiologically linked.
    • The cases do not share a household.
    • The cases are not identified as close contacts of each other in another setting.

What is not displayed on the COVID dashboard?

Each contact trace provides detailed information on the positive individual, close contacts and others. Because each contact trace is unique, there are varying reasons why some information may not appear in the COVID dashboard — even though you might be hearing about it in your community. The following information provides details on what is not included in the dashboard, along with some examples of when this might occur.

  • Positive individuals who received a lab-confirmed positive COVID-19 test result and were not in a Bellevue School District facility during their infectious period. For example, this might be an individual who was in quarantine and then tested positive after several days at home. This is because this individual was not in a Bellevue School District facility during their infectious period. Also, infected family members of students or staff do not generally appear in the dashboard unless that person was in a BSD facility during their infectious period.
  • Quarantines that occur for individuals as a result of an interaction outside of the Bellevue School District will not be reported on this dashboard. For example, students that are close contacts of a parent who tests positive and must quarantine will not be reported on the dashboard. In addition, close contacts that occur during a weekend gathering, party or event that is not school sponsored will also not appear on the BSD dashboard.

What can I tell from the date and location information on the dashboard?

The date column in the BSD dashboard refers to the last day during the infectious period that the COVID-positive person was at that BSD location.

Does every data point on the dashboard represent a unique COVID-19 case?

No, a COVID-positive person may appear several times on the dashboard. For example, some employees travel between locations as a part of their role. Or, a student may travel to another school for a class, activity or sport. If an employee or student visits multiple locations in the district on multiple days during their infectious period, each location will be listed.

Sample Scenario: A more specific example would be if a student attends Sammamish High School, takes a CTE course at Newport High School, and also travels to Interlake High School as part of a sports team. Later, this student tests positive and the contact trace finds that the student was at all three locations during their infectious period. This one case would be listed three times on the dashboard — once each for Sammamish, Newport and Interlake.

How does the data get added to the dashboard?

The information on COVID cases in Bellevue School District is updated upon the completion of the contact trace. Once all information is collected, the information is entered into a database by a trained contact tracer. This information is pulled once daily into the dashboard.

I got a phone call/letter from my school or work location about a positive case of COVID-19, why don’t I see it on the dashboard?

There can be a delay between when individuals receive a call or letter related to a positive case of COVID-19 and when it appears on the dashboard. Bellevue School District prioritizes informing individuals as quickly as possible during the contact trace. The trained contact tracers focus on communicating with the person who tested positive and all close contacts first, then the larger community. Therefore, it is likely that you may receive a phone call or letter about a case, and then see that information update in the dashboard a day or two later, following the completion of the contact trace and the daily update to the dashboard.
