Data Notes
Note on data update on May 22, 2020: We wanted to highlight two important data issues on the testing tab. The first is that about 11,000 negative lab results have not yet been entered into our data system. The second is that about 27% of negative test results do not have an assigned county. These two issues are impacting some counties disproportionately, including Skagit and Whatcom. For this reason, Skagit County’s data is temporarily unavailable on the testing tab. The impact is an artificial elevation of the percent positive in those counties. DOH is working to resolve these two issues.
Note on the county and unassigned data: This data changes rapidly as labs conduct tests and discover new cases. Labs assign those cases to a county. Counties or the Department of Health then determine the appropriate county of jurisdiction. Those don’t always match initially. We’re working to reduce the “unassigned” number to 0. Contact the local health department for county specific information.
Note on the deaths: Some deaths may be reported by health care providers, medical examiners/coroners, local health departments, or others before they are included in the statewide count. It takes longer for the state to announce deaths because they are often reported first to the local health department and then to us.
Note on the number of infections: Public health experts agree that the true number of people who have been infected with COVID-19 in Washington greatly exceeds the number of COVID-19 infections that have been laboratory-confirmed. It is very difficult to know exactly how many people in Washington have been infected to date since most people with COVID-19 experience mild illness and the ability to get tested is still not widely available.
