Wednesday, January 25, 2023: Washington Dept. of Health and Public Health – Seattle & King County data are still being affected by a security breach encountered by one of Washington's hospital organizations. As a result, cases, testing, and in particular, hospitalizations may be undercounted in October 2022 due to incomplete data. Recent data are more complete starting in early November through this update. We will update this message as the situation evolves and data flow is restored.
