In an ongoing effort to understand COVID-19 transmission and improve clinical outcomes in our community, Lake County Public Health tracks demographic, geographic and clinical information about confirmed COVID-19 cases. Key datasets are displayed below and will be updated as our data collection and analysis improves, as more information becomes available, and as regulatory metrics evolve.
Every effort will be made to update COVID-19 Summary Data every weekday by 1:30 p.m. Demographic Data & Epi-Curve will be updated weekly on Tuesdays.
Please be aware that the data presented here is not real-time and may not reflect the most recent information. Delays of up to a day may occur between the reporting of cases and recording times at the local, state and national data levels (the sources for this page).
