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 business day by 1:30 p.m. Demographic data, the Epi Curve, and Testing data will be updated weekly by Tuesday.
Public health officials and staff are monitoring data daily, and will update the website data on business days.*
*In observance of upcoming holidays, website data will not be updated December 24-25 or January 1.
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).

When there are more than 10 cases in each group, the data will be reported separately.
