Pacific Northwest Respiratory Virus Epidemiology Data

Overview

Combining data from the University of Washington (UW) and Seattle Children’s Hospital (SCH) healthcare systems, this dashboard provides historical and current tracking of respiratory virus testing in the Seattle area. Data are aggregated by week (Sunday - Saturday) and are updated once a week on early Monday morning.

Some important notes:

• The SCH test results start from October 4, 2020. When the displayed data includes tests both from prior to October 4, 2020 and from SCH, a grey dashed line is displayed to denote the beginning of the SCH data.

• The SCH data do not distinguish between rhinovirus and enterovirus. These tests are categorized as rhinovirus.

• A single test for human coronavirus testing (not including SARS-CoV-2) at UW was replaced with four tests for the OC43, 229E, NL63, and HKU1 subtypes on October 4, 2021.

• For the count numbers provided below, each “order” is one respiratory virus panel accession (at SCH) or battery (at UWMC). Clinically, each of these orders is often a panel that tests for multiple viruses at once.

• For the plots, tests for separate parainfluenza or coronavirus (not including SARS-CoV-2) viruses are grouped into one test count and result (e.g. all 4 parainfluenza viruses are grouped into a single parainfluenza virus test). The test is considered positive if any virus in the group is positive. Virus-specific data for these viruses is displayed in the separate “Virus-Specific Data” tab.

• Inconclusive test results are not considered positive tests.
