Communicable Disease Data Portal
Public Health – Seattle & King County (PHSKC) receives and investigates notifiable condition reports according to the Washington Administrative Code (WAC). Following an investigation, reports that meet laboratory and clinical criteria are considered "cases".
This page includes a table and a dashboard highlighting the number of cases of each condition reported to PHSKC. The dashboard also includes details such as, rates, demographics (age, race/ethnicity, sex), geography, risk factors, outcomes (hospitalizations, deaths), and laboratory findings. This data is collected through case interviews, clinical and laboratory reports. Data for certain options may not be shown if the total number of cases is under 10.
